I found quite an interesting fossil last week. I thought it was just a piece of bivalve shell, then turned it over and realised there was a xenomorph of an ammonite on the other side #FossilFriday #fossils #ammonite

A portion of the late-surviving osteostracan Escuminaspis from the Late Devonian of Miguasha (UMMP VP 110611) for #FossilFriday.

Dark, sickle-shaped fossil consisting of individual tesserae. It is preserved on dark gray matrix. Specimen cabinets are apparent in the background.

#FossilFriday blog post about #SaveTheSternberg. I have some thoughts based on what I have read over the last few days and it is not a good look by #FHSU admin. It really looks like closing was always the plan. But they did not count on us.

I had a wonderful time this week at the Marine Reptile Conference at Oxford. Lots of fun chatting about ongoing croc work, and super proud to see Max who I co-supervised present on his master’s project 👏🐊

Huge thanks to all the organisers for making this conference happen!

#FossilFriday Erika Martha von Hoyningen-Huene was one of the only two female vertebrate palaeontologists in the pre-World War II history of Germany. She completed her doctorate in 1933, the same year that Hitler came to power.

Happy #FossilFriday!🦌

🦴This week we have a tragulid jaw in matrix with oncolites from the middle Miocene Siwalik Chinji Formation in Pakistan!

📸Thank you to Catherine Badgley for sending us this fossil!

Since we are going out for 10 days next week after, Tropical storm Rachael has cleaned off the site, to evaluate the Ironstone bonebed near the base of our Cretaceous section in eastern Utah for #FossilFriday a few pictures of ankylosaur and iguanodont fossils collected of the surface of the site.

This weeks #Lego #FossilFriday is #Ornithomimus.

In 1890, Ornithomimus velox was given a type species by O. C. Marsh. It was based off a partial hindlimb, and forelimb that had been found in 1889 by George Lyman Cannon.

A passenger's first experience in an #airplane will always be the most memorable.
And this particular pilot sees no overarching need or desire to set any silly new precedent in this regard.

A cast of UALVP55700, a Saurornitholestes specimen representing the most complete dromaeosaurid yet known from Alberta. I’ve seen the original specimen up close but this cast does it justice. From the tip of the snout to the base of the tail this specimen is pretty much all there #FossilFriday

#fossilfriday A decent sized juvenile tooth of the megatoothed shark Carcharocles chubutensis on the beach at Crab Bank, a fossil-rich sand bar in Charleston harbor (SC), found while working on the boat with Ashby Gale of Charleston Fossil Adventures in fall 2023.

A large triangular shark tooth with a thick root and a serrated crown; the crown is dark bluish gray and the root is black. It's sitting on a fine white sand beach.

Upper left: Photograph of an articulated branch system of Lepidodentron aculeatum from the Bashkirian (Pennsylvanian, upper Carboniferous) of Hagen-Vorhalle, Germany (WMNM P85752). The specimen is approximately 350 cm long and about 200 cm wide (scale bar on the right is 100 cm).

But, before starting, there's something I'd like to say on the Crato Formation's fossils for #Fossilfriday.

#Cheliceratime
2/4

Today's species comes from the Crato Formation, a Brazilian geological formation from which incredible fossils have historically been stoled from Brazilian people by European countries & plunderers. There are many other similar situations like this across the world, paleontology's history is plagued by colonialism & neo-colonialism, but the Crato Formation is one of the more accessible and documented cases to talk about right now.

Crato’s fossils are often seized by customs, and several specimens have been at the center of juridic fights with European museums refusing to give fossils back to local communities & scientists, infantilising them and going against basic human dignity and respect for heritage. Paleontologists have a role to play in all of this, and more & more people act to ensure locals have a central part in all of this.

Mark my freaking word:
FOSSILS & COOL ROCKS WILL NEVER BE WORTH MORE THAN RESPECTING OTHERS.

Science helps us to understand the world, and to do so we always make choices on what we talk about or what we decide to test. Choices affecting others, choices showing how we view human interactions. Political choices. Science has always been political, and it's up to all of us to make it better and not continue to fund human suffering.

And I frankly don't give a sh*t if you disagree. Human lives, basic rights & dignity aren't up to debate. And I'll include something like that in future posts each time it's needed.

What time is it? It’s #Cheliceratime, #Fossilfriday & #Arachtober !
For this triple occasion, we're talking today about a cretaceous vinegaroon!

All the basic infos are here but if you want to learn more, there’s more in the thread below!⬇️🧵

1/4

This vinegarroon is one of the few named species of this order from the entire Mesozoic era. It already looks quite modern in every details, and shares a lot of features with the current vinegarrons living in the Americas.

Size : 12-ish cm of body length
Time period : Early Cretaceous
Paleoart speculativometer : Few missing details

The animal drawn is a vinegaroon, an arachnid looking a bit like a scorpion with long thin first legs used as antennae
