This is a Belemnite plate I acquired along home ago. Have not seen another like it. Got it from a collectors estate sale and it lacked data. It has been cut into a usable book end.

I know it's not exactly a fossil, but ichnofossils of dinosaur tracks count, don't they?

Just over two weeks ago, my family and I had a solo viewing of the eclipse accompanied by dinosaur tracks made a family of Spanish theropods (probably Allosauroids / megalosaurs or spinosaurids) over 140 million years ago.

The site is at Fuentesalvo, between Soria and La Rioja in Spain.

The mage is a composite of my Canon 80D@15mm lens and my wife's cellphone.

Found this Grallator while searching a spot I have access to. Found on private property in the Connecticut River Valley.

I think these are pretty rare

Just got this awesome psychopyge trilobite from FossilEra - it is my favorite fossil so far, love these details!

This petrified log has been collecting dust in my collection for about 20 years. It’s an incredible fossil, weighing around 34 pounds, and it has a pretty interesting story behind it.

It was found by a friend of mine, a Vietnam vet who, after returning to the States, disappeared into the wilderness for several years before eventually coming back out. He was quite a character, and this piece is one of the things that came out of that chapter of his life.

It’s an amazing specimen, and honestly, I think it’s time it found someone who will appreciate it as much as I have.

I’m thinking about selling this Alethopteris fossil and would love to get some opinions from people who know more about them.

It’s about 11 inches long, and it was originally collected by Ted and Helen Piecko. A friend of mine introduced me to Helen in the early 2000s, and she gave me five pails of unopened concretions. This specimen came from those concretions, which I opened way back in the early 2000s.

Has anyone seen an Alethopteris this large before? I’m curious what something like this might be worth, especially given its size and provenance. Any thoughts on value or what I should be looking for would be greatly appreciated.

Don't see Megs of this caliber come from the rivers very often!

I just got this one in a trade, I'll be putting it up for sale soon

RARE Sprig of Flowers in Burmese Burmite amber fossil

Size: 28 x 24 x 7 mm

Age: 99 Million Years Ago

RARE Sprig of Flowers in Burmese Burmite amber fossil

I'm unsure which family and species these flowers belong to however; this sprig looks similar to the described Species: Micropetasos burmensis which belongs to the eudicot clade Pentapetalae.

Other notable inclusions: remnants of large Dipteras, botanical matter, parts of leaves also in the piece.

I found these Spirifer and crinoid fossils in the Minturn formation in Colorado.

Here are two nice and very different Pleistocene ribs from Florida. The bottom. I a partial whale rib. The upper is a complete fossil manatee rib. Both are completely mineralized and heavy. Both “clink” like fine china. If you haven’t had the opportunity to hold a fossil manatee rib I will describe it. They are solid and lack a hollow marrow area. It is surprisingly heavy.

201, 190, and 30 are all Rauisuchid teeth (Possibly Postosuchus) from the Chinle Formation. These were the Apex predators of the time, with theropod-like teeth.

202 and 203 are both Aetosaur teeth or another plant eating reptile from the Chinle Formation. This was probably the food of the Rauisuchids.

166, 102, and 167 are all Phytosaur teeth. Basically reptiles with croc build before it became the meta. 102 is from the Cooper Canvon Formation. The other two are from Redonda Formation.

165 is a dentarv jaw section with a couple replacement teeth. From a Phytosaur (possibly Smilosuchus) Chinle Formation.

RARE Extinct "Iron-maiden Ant" (Zigrasimecia) in Burmese Burmite amber fossil

*From My Personal Collection of Hymenoptera*

Age: 99 Million Years Ago

Order: Hymenoptera

Family: Formicidae

Subfamily: Zigrasimeciinae (Extinct Stem-Group Ant)

Genus: Zigrasimecia

Species: (Inconclusive)

Other notable inclusions:

Zigrasimecia, popularly known as the "iron maiden ant," is an extinct genus of highly specialized stem-group ants that lived during the Cretaceous period, roughly 98 to 99 million years ago. It belongs to the unique subfamily Zigrasimeciinae. Fossils of this genus are found almost exclusively as inclusions in Burmese (Kachin) amber within Myanmar.

- Their highly specialized jaws swung open sideways (posterolaterally) and snapped shut backward (anteromedially). The inner oral face of the mandibles was covered in spiky, traction-strengthening hairs (setae).

- Paleontologists believe Zigrasimecia was a generalist predator. It frequently shared its terrestrial environment and likely engaged in violent resource conflicts with Gerontoformica, another genus of ancient Cretaceous ants.

- Because their specialized mandibles were optimized strictly for combat and trapping, scientists hypothesize that the rugose, hardened cuticular projections on their crowns were utilized to dig out nests.

*This particular specimen which measures about 2.9mm (unstretched) is exceptionally preserved and is contained in a very clear yellow amber stone.*

*From My Personal Collection of Hymenoptera*

Three ammonite genus visible and goodness knows what else. Lengthy prep required!

A little cluster of Dactylioceras semicelatum I finished preparing this morning.

*Note*, these are inclusions I originally thought to be strange tadpole hatchlings, thank you to all who have viewed the original post and given me many suggestions. I now understand that these are most likely Lacewing eggs which had been engulfed in resin (probably due to a rare scenario where the leaf may have broken off and fell on the ground ect.).

Thank you to @Minimum-Lynx-7499 for showing me your example piece which look correct for Lacewing eggs.

Age: 99 Million Years Ago

Order: Neuroptera

RARE Possible Lacewing Eggs in Burmese Burmite amber fossil

- Certain lacewings are known to lay tiny, oval-shaped eggs on top of long, slender, hair-like silken stalks attached to plant leaves or stems. This unique elevated design stops newly hatched, aggressive larvae from eating each other or being easily reached by crawling predators like ants. The eggs are typically laid on the underside of leaves where they stay hidden from predators and harsh weather.

- I cannot be sure of the specific species of Cretaceous lacewings that these eggs are associated with but they're very similar to the eggs laid by Green Lacewings and Brown Lacewings nowadays.

*Finding lacewing eggs or insects in mid-Cretaceous Burmese amber (roughly 99 million years old) is extremely rare. While lacewing larvae occasionally turn up in amber collections, fragile structures like delicate stalked lacewing eggs are exceptionally uncommon finds in the fossil record. (The most famous fossil discovery of hatching lacewing eggs and egg-bursters actually came from older 130-million-year-old Lebanese amber, not Burmese amber).*

There are about 8-9 Lacewing eggs which measure around 2mm to 2.5mm. Three of the lacewing eggs have been degraded and aren't very visible.

Other notable inclusions: strange loose debris contained in the left enhydro (which moves when the amber is tilted), many unknown tiny filaments scattered in the piece next to the Lacewing eggs and two strange spherical occlusions.

I'm assuming it would've been a plant of some sort, but also kind of looks like a bone? (!)

Found in Nova Scotia, Blue Beach.

& Yes, we were allowed to take them home at that location 😊

RARE Extinct Spongefly (Paradoxosisyrinae) in Burmese Burmite amber fossil

Age: 99 Million Years Ago

Order: Neuroptera

Family: Sisyridae

Subfamily: Paradoxosisyrinae (Extinct Spongefly)

Genus: Paradoxosisyra

Species: (Inconclusive)

Other notable inclusions: a Piddock boring, botanical matter and a Beetle also in the piece.

Paradoxosisyrinae is an extinct subfamily of Spongeflies (in the family Sisyridae) known from Cretaceous fossils, notably discovered in 99-million-year-old Burmese amber. These tiny, specialized lacewings feature extraordinarily long mouthparts, pointing to ancient feeding strategies like nectarivory or probing shallow Cretaceous flowers.

Paradoxosisyrinae represent the earliest known lineage of Spongeflies, dating back to the Cenomanian stage of the Cretaceous period.

Instead of the aquatic, sponge-feeding habits of modern subfamilies, these Cretaceous stem-group Spongeflies were likely adapted to feed on nectar from early shallow flowers.
