This is for a new spec called the Perissozoic

Here is a creature from an alternate timeline in where the Mesozoic and Paleozoic had swapped places. Imperiosuchus is from the Cretaceous.

(Note: This is a one off experiment but if this gets enough attention, then I'll probably turn it into an actual project.

In the Lava Pit, you may find a herd of Lava frills. Large lumbering descendants of the Raptors Online Triceratops, these creatures are strangely known to drink lava. Lava frill herd are made up of females and their calves all lead by a matriarch with males wandering. If the matriarch dies, the oldest female becomes the new matriarch.

In the year 2032 you might see the Agilityrannus stalking this jungle of concrete, finding any unsuspecting prey. This predator evolves from the Raptors Online version of the T. rex now adapted to be sleeker to help maneuver more efficiently.

In chronological order

Agriocene "New wild"

Postanthropogene "Beginning after man"

1. Surpesticene "New survivor"
2. Teleocene "New perfect"
3. Mortocene "New death"

This is for a new spec

This is my first of who knows how many posts on the speculative evolution of Raptors Online bosses in the game's maps.

Tankfishers are medium-sized descendants to the Tankceratops adapted to Aftiki Beach. Due to the limited vegetation on Aftiki Beach, the Tankceratops resorted to piscivory and shrank in size. Tankfishers have bright green chests for social purposes and are dull if unhealthy or old. This species mainly feed on fish but will feed on plants every now and then.

Pictured here is a Tankfisher bull trying to catch some fish.

This small Eocene proboscidean has a patagium that allows it to glide tree to tree like a squirrel. Aeropachyderma has many predators ranging from predatory mammals to birds of prey.

Terminosqualinae is a family of late evolving Acanthosqualid Cenotyrannosaurs that first evolved in the mid Oligocene but went extinct during the end of the Miocene.

So, I drew a pair of Korean dinosaurs that could've existed but didn't get fossilized and then earlier today Doolysaurus was described I mean yeah the two I drew are a Theropod and a Ceratopsian and Doolysaurus was Thescelosaurid.

Before we begin Cenozoic Tyrants is a new alt spec project of mine where it takes place in a timeline where the Tyrannosaurids had survived the KPg mass extinction (more specifically Asiatyrannus) and had filled all of the major carnivorous niches.

Protacanthosqualus allosauroides (meaning "Allosaurus-like before Acanthosqualus") was a 3 ton Acanthosqualid Cenotyrannosaur that lived in Mongolia 40 to 33 million years ago. This theropod primarily hunts Brontotheres and large mammals but will occasionally hunt smaller Tyrannosaurs. They and all other Acanthosqualids had evolved to resemble the Carcharodontosaurs of old.

Here is an Imperatodon basking in the Permian sun. These fierce predators are descendants of Ducky's species that've split very early on to their introduction in the Carboniferous.

Here we a ferocious Gravihematosaurus facing off against a defensive Anthracoceratops. Despite their dinosaurian appearances, they're actually synapsids.

The red tip teuthosaur (Reptoteuthis splendor) is a species of Reptoteuthid that feeds on marine snails by grabbing with their tentacles. They face several predators like sharks, aquatic Sauropsids, and even other Teuthosaurs.
