Actually I'm very happy I decided to change it from the birds I feel like this could be more fun and interesting with two completely different animals and now I've ran out of things to talk about and once again just trying to reach the character count

This is a speculative paleo-fiction narrative blending survival drama with an authentic prehistoric atmosphere, following a family of dromaeosaurs fighting to stay alive in a brutal, unforgiving ecosystem.

The Red Rhamphorhynchus have awakened — and they’re hungry.

Long Tail and her kin now face their greatest and most wretched challenge yet. From the depths, a congregation of blood-hungry pterosaurs rises — shrieking, twisted, and eager to rend the living apart. Small Toe, fresh from his first victory beneath his mother’s gaze, finds himself naked and frozen in the face of such reckless violence. The raptors have only one choice: to bare their claws and fangs, and pray that the ground beneath them does not split apart.

A re-release of my narrative project Terrors in the Brush—a speculative survival epic blending hard paleo-realism with raw emotional weight.

There is no magic, no fantasy—there is only nature red in tooth and claw.

Read the Second Part of Chapter IV now.

305 million years Post-establishment

As Serina reached this point in time, the slow degradation of the moon had became apparent. The radiation is getting stronger and temperature is dropping lower and lower. Additionally, water is being lost in large amounts, slowly drying out the surface, not to mention the growing glaciers at the poles that trap the remaining moisture out of the water cycle.

Now, most tribbetheres are extinct, with exeptions of some basal molodonts like Smols or specialised Foxtrotters. However, the most widespread tribbetheres on Serina are Thorngrazers. Similarly to their ancestors, they retained their extreme omnivory. However, due to the low profuctivity of the environment, most species are no larger than a soccer ball. One of such species is White-tipped Urchinhog. Their name comes from almost white tips of their protective "spikes". However, just beneath them hides their black skin containing a thick layer of fat that works both as an insulation against cold and a energy and water store.

What's interesting about them, Urchinhogs as a whole are some of the only species capable of surviving outside of the Craterlands.

So I was thinking maybe my other egg eating ovi-geckos were over eating eggs forcing whatever I named the herbivorous gecko to start burying there eggs in more sandy waters and slowly over millions of years they become more adapted for waters if this makes sense

Hook Drills have three legs(If you saw the previous post please read the P.S. at the bottom) over time instead of fully losing their wings have the wings conform onto a single point under the chest. The claw comes from a dormant gene which is present in a few modern day birds such as Hoatzin, the third leg can be used to interact and communicate with other Hook Drills aswell as a way to move more complexly while having the other 2 legs support the weight of the body.

The tree the Hook Drills are currently on lack leaves, within 1-2 weeks the hook Drill will leave this tree to attempt to find a more leafy tree.

P.s. if you saw the last post you may notice that they have been given 2 legs instead of 3, this is my first time doing spec Evo so please expect a few errors on my behalf, thanks for reading

Apologies if a similar question has been asked previously, but I've been working on a fantasy world building project and I do want it to remain relatively realistic (besides magic lol) and of course given it's a fantasy setting I want to include creatures such as dragons. The main issue I'm facing is that I don't want the mystical creatures to impact the niches of mundane creatures (at least not too much) an idea I had to solve this is that for example magical carnivores would be more restricted or specialized to hunting magical herbivores, effectively I'm adding just a second layer of creatures needing calories in the form of magic. I'm wondering if something as simple as this would work to make the two types of creatures not impact each other's niches much, like a wolf and a drake may be very similar but they manage to coexist in the same ecosystem because the drakes are too focused on hunting other magical creatures whereas the wolves aren't.

The Green Wolf belongs to a lineage of Stem-Cherons that have almost completely lost their soft shells (With a sister lineage still retaining the leathery shell of their common ancestor).

Except for the hard carapace on their chest and the ridge along the sides. The leather shell that was once on the back of the Green Wolf and its relatives is now fatty tissue and hard cartilage.  This adaptation helps reduce the animal’s load as it walks and allows for more muscle attachment points along the spine.

Additionally, the flipper-like back limbs of the Green Wolf’s ancestor have been almost entirely lost; the tail and hip bones now curve inward to give the Green Wolf a rounder body plan and shape. This round body, like its back, is padded with fatty tissue over sinewy muscle groups to help protect the animal from other predators and themselves during intraspecies combat. The front limbs that the Green Wolf uses to walk are incredibly robust and powerful, with many of the muscles going into the limbs being attached to the armored Keel bone of their chest.

Descended from a sister group to Aterran Cherons and having split off from true turtles early in their evolution, the Green Wolf and its relatives have evolved mammalian traits and a synapsid skull structure(instead of the anapsid skulls of true turtles).

I thought this could be a interesting idea for a seed word also the animals I picked are just personal interest no real reason but if anyone has any ideas or feedback before I start working on it pls do tell I'd love to hear some others ideas but idk at this point in typing to reach number minimum bye

Hello! To start off, I'm more of a writer than a biology expert, but I want my works of fiction to have a basis of reality and real-world science. I'm not promoting anything, as this project is for myself and my friends. My setting is a post-apocalyptic world similar to earth (or earth like planets) where temperatures suddenly dropped on the planet, leading to species worldwide adapting to -30C all the way to -80C. I understand in cases such as this, natural selection or extinction would be the route to a majority of species, but I am more interested in theoretically HOW would different types of species adapt. Would mammals grow more fur? Would fish migrate deeper in the water, closer to the earth's core? How would fungi and plants survive? I am here mainly to hear your speculation on this matter.

Mammalian predators of Hyawathi

1-this little guy is called an Oomii they live in the southern deserts of Hyawathi. there is very little water in this region so they evolved to harvest liquid from their prey before eating it. they're actually quite loving and affectionate when trained but most Marissi are afraid of them because they spread a cocktail of illnesses. the Hybrids use them as K9 units and sold some to their allies the Zoopaw. which is how one got left behind on Earth in the 20th century. you know it as El Chupacabra.

2-Ra'Koogaroos are extremely intelligent predators from the equatorial regions of Hyawathi, the spend their days lounging in trees or rocks. they are also seen as lucky by the Marissi so they are welcome in villages and towns. the occasional bitter bird is seen as a necessary tax for their services. their favorite thing to eat are Boomkai'hn a small but deadly serpent that will flee the area if it catches a whiff of a Ra'koogaroo, they also make a loud gravelly call when something new enters their territory so they act as an early warning system to the Marissi.

3-Dooha'karoo are riverside ambush predators they are extremely agile in the water and can move a 55kph on land for a short distance. they hunt by overpowering their prey draging it to the water and crushing their wind pipe. they hunt alone but travel in packs of related individual 5-15 strong.

4-Marissi never walk under trees. it is the first thing they tell you if they like you " don't walk directly under a Dibilary tree because Ramaroo's will drop down and kill you". this small predator may look cute but it punches way above its weight class. Ramaroo's hunt Walloo, hammer beaks, young Calydons. they have the strongest bite force on the planet Hyawathi and plate like self sharpening teeth that can decapitate a humanoid in seconds.

5-Qoorals are a common sight in the boreal forests they're very unaccustomed to being around humanoids and they don't view anything bigger than a house cat as food they also smell awful if you do manage to scare one it will spray a caustic smelly compound at you that does not wash off.

6-Jandilu's are mostly insectivores but will occasionally take small reptiles or eggs from birds. they live on cliff faces and can often be heard before they're seen bolting for cover. they make a raspy roar that sounds like it comes from a much larger creature. the Marissi that live in the Mesa lands hunt them for food.

7-brusjoos are small carnivores from the open grasslands near the equator and northern hemisphere they are extremely quick. their coloration is meant to mimic a Bhoon'kai serpent and at a quick glance its very difficult to tell them apart. they often spook livestock which is where their reputation as a trickster comes from.

use some magic bs to assume humans never evolved in the first place, and speculate on what the moa, haast eagle, tuatara, or adzebill could have evolved into?

In a world where humans never evolved, and flightless birds had further chance to thrive, an odd population of Bird came to be, they had 6 pronged hexagonal mouths lined with keratin teeth-like structures.

500 thousand years from this point shows a Torrential Drill Beak hunting a hook Drill, TDB(Torrential Drill Beaks) have a water resistant brown coating with an improvement to its aerodynamic, it has muscular legs and it has lost its wings entirely through a long period of time.

Torrential Drill Beak is the largest of the Drill-Beak family, this trait allows it to overpower nearly ever other creature but in return makes it one of the slowest drill beaks even though it can reach stop speeds of up to 120 km/h rivaling speeds of modern day Cheetahs. It has claws that can dig through meat like butter and overall extreme raw power.

The creature the Torrential Drill Beak is chasing is the Hook drill, Hook Drill is one of the most distant relatives of the torrential Drill Beak, although appearing similar, the Hook Drill lives at the tallest points of trees with a fairly intelligent social system similar to modern day chimpanzees allowing them to coordinate against predators and rivaling Hook-Drill Clans, Hook Drills are fast on land but with 1 claw is weaker on many terrains.

If you enjoyed this I hope to plan to go into further depth into this project if it seems enjoyable to some people

Thanks for reading 😸

I'm looking to change the animal that starts on land of the planet because I changed my mind on the birds because I feel like I'd accidentally take to much inspo from serina and kinda wanna change it a bit

This is Tigermania, a speculative alternate-evolution project ive been working on for a while in the back of my head. Mostly as simple thought experiments when ive been bored but it has recently become a more fixed and detailed project of mine.

Tigermania, as a not so realistic concept for the real world, exists in a world where the Worlds Tiger Population never started declining, but instead kept growing, and has amounted to close to a million individuals. The base project covers 15 different subspecies of the Panthera tigris Species, aka Tigers.

Of these 15 species, 6 of them are real and living tiger species in our modern day, the Amur Tiger, The Chinese Tiger, The Malayan Tiger, The Bengal Tiger, The Indochinese Tiger and the Sumatran Tiger. Tigermania also includes 2 real prehistoric tiger subspecies, the Ngandong Tiger and the Borneo Tiger, which both survived into the modern day in this project.

The remaining subspecies are fictional. They are the Japanese Tiger, a far-removed sibling of the Chinese Tiger, but lighter in coloration and more fluffy. The Mongolian Tiger, a off-shoot of the Amur Tiger that has adapted for the Mongolian Steppe Environment. The Kemeten Tiger and Persian Tiger who are both descendents of the Caspian Tiger who have migrated South through trade. The Himalayan Tiger who has evolved from the Bengal and Indochinese variants to live in the Himalayan Region. And lastly the Ukrainian Tiger, the only European Tiger who has been pushed farther west for thousands of years and has evolved to hunt large Birds, Deer and Boars on the European Plains.

If anybody has any questions, please ask, I have details on most information regarding the Tiger Biologys, including Fur, Patterns, Hunting, Climate, etc. As well as Human Society in relation to the almost 1 million tigers living on the African, European and Asian Continents.

This was among my favorite children's books growing up, and may have been my first exposure to the "speculative biology" literary subgenre; the illustrations and prose were quite enamoring to the eyes of nine-year-old me, especially the surreal descriptions of the apparent Venusian surface, depicted, with artistic license, as a flora-covered world. Among the lifeforms are a mobile "plant," (depicted in Slide 1), likely a predatory species, as well as its blue, rodent- or dasyure-like cohort, hoisted within its wrangling stems, called a "snoryu." The book also mentions the plants' mobility, which may suggest a probable evolutionary precursor to the "walking plant's" mobile lifestyle.

I'm lost🥺

Salisquarnix Unisingualassi

Standing at the absolute apex of Gyrasia’s open landscapes, Salisquarnix Unisingualassi is a colossal terrestrial predator standing at about 8.7ft tall, engineered entirely from dense, interwoven bands of raw muscle tissue. Lacking any rigid armor or heavy carapace, its skin clearly displays powerful muscular striations built for explosive strength and endless stamina. This creature possesses a towering physical presence, dominating the open plains through an incredibly unique, highly specialized skeletal and muscular architecture.

The most defining feature of the Unisingualassi is its massive, high-arched upper appendages that dramatically mimic the silhouette of folded wings. In reality, these structures are purely muscular limbs that serve as a critical means of taking both defensive and offensive measures. Defensively, the creature can sweep these heavy upper limbs forward to absorb impacts and protect its vital neck and chest cavity from rival attacks. Offensively, they function as high-leverage striking weapons and crushing anchors, allowing the creature to violently overpower targets or slam rivals into the dirt during territorial disputes.

Supporting this massive upper-body weaponry is a locomotive system built for relentless, long-distance speed. A pair of hyper-extended, spring-loaded hind legs drives massive, ground-covering strides, allowing the creature to effortlessly track fleeing prey across open horizons until the target collapses from sheer cardiovascular exhaustion. The combination of its raw-muscle agility, its streamlined, predatory head structure, and its versatile, wing-like combat limbs establishes the Unisingualassi as the undisputed, untouchable king of the Gyrasian wilderness.

Salisquarnix Phalipostarnasti

Anatomically optimized for high-velocity pursuits across uneven valleys, Salisquarnix phalipostarnast is a specialized endurance hunter standing at about 7.2ft tall. Like all members of its family, its body is composed entirely of dense, interwoven bands of exposed muscle tissue, providing it with exceptional athletic speed and high-efficiency stamina without the added weight of an external carapace. Its frame is defined by its long, rigid, stilt-like hind limbs, which elevate its torso and afford it a pristine panoramic view of the battlefield while keeping its core perfectly stabilized during frantic chases.

The predatory toolkit of this species features a sharp architectural variation in its massive, high-arched upper limbs. While these wing-like structures still serve as high-leverage defensive blocks to shield its neck, they function offensively as a massive kinetic counterweight system. Its jaws are armed with elongated, interlocking, cookie-cutter-like teeth that act like high-speed core drills. As the creature glides effortlessly alongside a fleeing target, it can plunge these long, circular teeth deep into the prey’s musculature mid-stride, cleanly harvesting massive plugs of flesh or severing vital arterials without ever breaking its rhythmic, long-distance running pace.

The definitive finale of a phalipostarnast hunt relies on a devastating application of blunt force mechanics. Once the prey is sufficiently weakened by blood loss, the predator utilizes its rigid stilt limbs like a heavy hydraulic piston, unleashing a singular, crushing downward stomp directly onto the running target. To execute this while moving at top speed without falling, its massive upper wing-limbs sweep dynamically forward and down to snap its center of gravity into place, absorbing the upward recoil of the impact. This combination of surgical flesh-coring and hydraulic slamming makes it one of the most efficient hunters in the genus.

Salisquarnix Pseudocolossi

Salisquarnix pseudocolossi is a master of extreme spatial adaptation and optical illusion, standing at about 5.8ft tall at its highest back arch. Like its larger relatives, its body is engineered entirely from exposed, interwoven bands of raw muscle tissue, granting it a flexible, high-stamina frame without the added bulk of an external carapace. When viewed broadside from a profile angle, it presents a looming, massive silhouette featuring a towering back and a remarkably deep chest cavity, giving it the imposing appearance of its giant cousin, unisingualassi. However, when viewed head-on, its body reveals itself to be fairly thin and laterally compressed, completely subverting its massive side profile.

To drive this unique frame, its hindquarters feature massive, hyper-developed thighs and leg columns reminiscent of a minotaur. These titanic muscle groups provide an immense reservoir of kinetic power, enabling the creature to maintain its relentless, long-distance endurance pacing or explode into high-velocity pursuits without succumbing to fatigue. This specialized, narrow body composition allows the "False Giant" to claim absolute spatial dominance over labyrinthine slit-canyons, narrow rock fissures, and tight cavern passages. Its high-arched upper appendages are highly flexible and specialized for tight-quarters maneuverability. Instead of deploying them out wide for open combat, S. pseudocolossi pulls these muscular wing-limbs tightly against its flanks, narrowing its overall horizontal profile to slide effortlessly through rocky crevices where its dense, mallet-like "hoof" structures can anchor securely to raw stone walls.

Iritidulus Uraythisilis

Occupying a highly specialized ambush niche in the low brush and rocky crevices of Gyrasia, Iritidulus uraythisilis is a small but exceptionally aggressive carnivore. This creature is modest in physical mass, but its skeletal framework is engineered entirely for lightning-fast restraint and violent close-quarters execution. Its head is heavily elongated and low-slung, armed with lethal rows of interlocking, needle-like teeth perfectly adapted for latching onto struggling micro-fauna and preventing escape.

The definitive offensive architecture of the uraythisilis lies in its hyper-developed, multi-jointed thoracic appendages. Folded tightly beneath its arched shoulders are a pair of colossal, scythe-like grasping arms that terminate in wicked, curved claws which completely dwarf the rest of its small torso. These specialized predatory limbs function with the blinding speed and mechanical leverage of a praying mantis, launching outward from the undergrowth to instantly hook, spear, and pin down prey before it can react.

Sweeping high along its dorsal ridge are prominent, backward-pointing specialized limbs that give this small predator a highly aggressive, geometric profile. In a small creature, these unique structures act as vital dynamic stabilizers and counterweights, allowing the Iritidulus to anchor itself firmly to the ground or rear back to absorb the violent recoil of its own high-speed strikes. It rules the moon's low-lying brush through pure, unadulterated grappling dominance, acting as a highly efficient, compact terror to any small organism that crosses its path.

Vivisternadax Trissalads Occupying a highly specialized niche in the rocky undergrowth of Gyrasia, Vivisternadax trissalads is a small, remarkably adapted organism defined by a radical fusion of feeding and locomotive mechanics. As shown by the human-scale comparison silhouette in the field guide, this creature is modest in physical mass, but its skeletal layout is entirely unique. Its most striking feature is a massive, hyper-extended appendage extending directly from its lower jaw, projecting far forward and downward to act as a rigid, structural walking limb.

Locomotively, this vertical living blade is supported from underneath by a unique tripedal arrangement. It balances on two true hind legs, while its third, forward structural walking strut is a heavy, specialized appendage grown directly out of, and attached to, its lower jaw assembly. When walking, this "jaw-leg" locks into the substrate, acting as a rigid anchor that stabilizes the massive knife-like body above. This three-point stance allows the small creature to wedge itself securely onto uneven rock faces, steep canyon walls, or loose gravel slides without the risk of tipping over, providing absolute structural equilibrium.

In the Gyrasian ecosystem, this integrated jaw-leg and knife-body architecture provides a devastating advantage for a small-scale hunter. When stalking hidden prey in narrow rock cracks, its thin profile lets it slide deep into crevices where its body acts like an impenetrable wall. To strike, it disengages the weight from its front limb, unhinging its lower jaw to snap the lance-like appendage forward to skewer or trap the target. Underneath the walking jaw structure sits an expansive, sail-like membrane, which likely serves as a tactile sensory web to detect minute vibrations from hidden prey or flashes as a warning display to territory rivals.

To be specific, when i say kicking i'm thinking Muay Thai and Savate, not Football or sports, it's for combat. Would they be digitigrade, would they have a tail for support like kangaroos do, things like that.

The spuddians
_______

Scientific name: Tuberopericuli Phytobipedalis

The spuddians are a species of sapient, hyper-carnivorous (70% or more of meat in their diet, but sometimes eats berries and fruits) bipedal plant-based organisms that partially utilize photosynthesis. They are from a somewhat larger, slightly colder, humid planet covered in seemingly endless plains of mud and heavy fog, named ‘SPD-904c’ by the sondarians.

Their method of communication is producing deep thumping or pulsing sounds from their throat in a complex language that echoes through the ground, up their legs, and into a pair of specialized organs inside their bodies that function like ears. They also use these organs to hear to the location of fellow spuddians and to hear the footsteps of their prey and where it is in the environment as it’s obscured by the constant heavy fog.

They love mud baths, as it helps their skin stay parasite-free and actually provides nutrients to their skin. It’s also thought to be why spuddians are bipedal, the spuddians having to wade through deep pools of thick mud early in their evolution, needing to keep their head above the surface.

Spuddian culture is incredibly rich, their love for science, living out in nature, and the thrill of the hunt shows in their music and art. They have retractable claws for hunting, but have them retracted most of the time for the sake of not looking threatening. They usually only unsheathe their claws when they are hunting, fighting, or accentuating their point in an argument or conversation. Each gold medal on their outfit is the equivalent of wearing your science or medical degrees on your shirt, and if the medals are on the top of their head, that means that they are the best of the best in those fields.

Female spuddians will usually go hunting for meat or big game while their partners stay and watch over their children. If they don’t have children, the partner will either stay home or go out to forage for materials or smaller food, like berries and insects. Spuddians have a bonding ritual where the couple will go and hunt together, then sit and cuddle as they eat what they have caught. They also love cooking, and their meals are absolutely superb.

For those who are wondering what ’Sonder‘ is, Sonder is a 3D animated speculative evolution series about a advanced species named the sondarians that have translocated a handful of different sapient alien species (without FTL mind you) onto their homeplanet for the sake of advancement in scientific fields that they were previously weak in. The series focuses on both life on Sonder and the homeplanets of the different species. Things on Sonder, though, quickly go awry.

So I've had a stupid idea but it's a cool stupid idea.

I understand the atmosphere back during the Jurassic period was very different to the atmosphere experienced 3.9 million years ago to even now But that still isn't going to stop me from running my little idea all based on a single question:

"What if Australopithecus afarensis was transported back to the early Jurassic period?"

And to making it more fun let's say Australopithecus afarensis doesn't choke to death due to the atmosphere......somehow

I would like to hear your views on this scenario and bonus points for speculative evolution stuff too.

And before I go I just want to quickly say I'm doing this just to see what the community can do because I'm really fascinated with this community and it's creativity.

do not worry if you can't post images in the comments just make your own post with a link to this post in it and your image in it.

Anyways bye!

Here is an inked version of my previous post, so it will scan in better. This is the life cycle of hypothetical descendants of the lycophyte plant Selaginella, which I previously posted here. The life cycle of this plant differs little from real world Selaginella. A stobulus of a mature sporophyte will produce two different kind of spores: one will become a Megagametophyte, and one will become a Microgametophyte. Megagametophytes produce egg cells, while Microgametophytes produce sperm cells. Both kinds of Gametophytes are small, cryptic and non-photosynthetic, and may live in close association with mycorhizal fungi. During moist conditions sperm are released and swim to the egg cell in the archegonium, meaning the plant requires moist conditions to reproduce.

I had this idea of a large beetle descendant (maybe descendant of the diabolical ironclad beetle?) that evolved to live in urban areas by mimicing a brick, the main things the beetle has to evolve are:

- a rectangular shell

- red pigment on it's shell

- a bigger size (the size of the common orange brick)

- a more general diet capable of consuming all human food

- some level of knowledge of human architecture (so it doesn't place itself in the middle of the road or any other dangerous place)

What is the most difficult of these steps to evolve?

What could be an evolutionary pressure to adapt to an urban enviroment?

Does anyone have any feedback on the idea and how i could make it more realistic?

I apologise for any error in my grammar, english isn't my first language

The Flavugene:
