I hear it’s #fossilfriday and we recently went to Florida, mostly to look for fossils. (Yep, got some shark teeth.) We did some beach combing in between scheduled activities and found these lovely little oysters.

What did Neolithic people think these were? 🤔

This is a fossil sea urchin from 90 million years ago, found in the Neolithic flint mines of Grimes Graves in Norfolk

The ancient miners must have had stories about how all this sealife got there!

What time is it? It’s #Cheliceratime & #Fossilfriday !

Today I wanted to talk about how pseudoscorpions use larger animals as taxis, and that this behavior is known from multiple fossil examples!

Thanks for watching and I'll see you in the next Cheliceratime!

Some #FossilFriday news

For this week's #FossilFriday, here's an unpolished field photo of the thumb claw of Trierarchuncus, held in the hand of @denverfowler.bsky.social on the day of its discovery by Jack Wilson, 15 July 2015.

This claw would become the first catalogued specimen in the Badlands Dinosaur Museum (BDM 001)

For #FossilFriday, here's some 2019 #paleoart of Deinonychus subduing a juvenile Sauroposeidon using the Raptor Prey Restraint (RPR) model of dromaeosaur predation: grabbing prey with taloned feet, pinning it down with its body weight, and then eating it alive. Just like modern raptors, then.

カイラサウルスが記載されたので、福井県立恐竜博物館よりフクイヴェナトルFukuivenator paradoxus。
カイラサウルスの尻尾はフクイヴェナトルと比べてそんなに短くないと感じた。尻尾の短縮は思ってたよりも時間がかかっていたのかもしれない。

It’s #taphonomy time! 🦴

A LOT can happen between death and discovery, so understanding taphonomy is a great paleo detective skill to have 🔍💪

Head to bit.ly/ichthyosaur-jaw & tune in next week for another #FossilFriday from the Paleo Research Institute 👉

Holotypic skull of Goyocephale lattimorei in Fukushima Museum.

"The most spectacular mastodon molar that I've ever seen" (said by paleontologist Wayne Thompson), found by geologist Brigid Lynch in California creek bed. #FossilFriday #paleontology #womeninscience #nature #ecology

Happy #FossilFriday! New research on Priohybodus arambourgi reveals a surprising evolutionary story: despite the advanced serrated teeth, the internal dental structure remained conservative. Thin enameloid may signal generalist feeding.

Neat view of the pterygoid teeth of this mosasaur, basically clutching the mounting armature. #FossilFriday
