This weeks #Lego #FossilFriday is #Thylacosmilus

In 1926, in Argentina, three specimens were collected.

In 1928 they were reported to the Paleontological Society of America.

In 1933, although only preliminarily described, Elmer S. Riggs named them Thylacosmilus.

the value of museum collections - this project rapidly snowballed from Ryan Tokeley emailing me while surveying the Carnian collections in the Warwick Museum stores to say there is a specimen labelled as 'fossil shark' which led to a very fruitful fishing expedition #fossilfriday

as @palaeostephan.bsky.social has noted below, latest on Athenaegis @lisaschnetz.bsky.social did a lot of the work, funding from @leverhulme.ac.uk "feeding without jaws" @dragonsofwales.bsky.social produced a stunning reconstruction for @lapworthmuseum.bsky.social temporary exhibition #fossilfriday

#FossilFriday: The pelycosaur Dimetrodon, on display at the Royal Belgian Institute of Natural Sciences in Brussels.

#FossilFriday Complete skeleton of Hemicyon sansaniensis, a fully carnivorous and cursorial bear from the Middle Miocene.

#FossilFriday Barbie has had a lot of careers over the years, including Paleontologist Barbie in 1996!
USPS has Barbie career stamps, and of course the paleontologist made the cut 🦴💕

For #FossilFriday, a screaming oreodont. I feel ya. 🧪⚒️

When you meet Homo sapiens creatures for the first time, it can be a little unsettling
(Absolutely GOBSMACKING, even).

This crinoid was damaged and started to regenerate the arms, just like starfish & other echinoderms.

This one did not have a snail attached, but studies have shown increased regeneration if a snail was present. Armored fish may have been looking for a snail dinner and broke an arm.

This is another Arthroacantha carpenteri crinoid from the Devonian Silica Shale. It doesn't look as nice as the previous specimen, but it's one of my favorites.

Take a closer look at the arms.

The left two arms are about half the width of the rest of the arms.

#fossilfriday Everyone is telling me I should do a book on Texas fossil vertebrates. So here is one of them. This is Tylosaurus rex, a giant mosasaur from Texas. On display at the Perot Museum of Nature and Science, Dallas.

This specimen also has a Platycerid snail attached to the tegmen or top of the calyx. Snails are often found on certain crinoids and would drill holes into the calyx. This snail is gold colored from pyrite.
