More #fossilfriday fun. Two skulls of the dinosaur Thescelosaurus (both real). Same formation, roughly the same body size. Why so different???? Male vs. Female? Different species? Geographic variation? Hard to deciphere when there are only about 5 well preserved skulls known.

Surprise #FossilFriday... from the present! This is Neogymnocrinus, a bizarre deep-sea crinoid and member of a once-diverse lineage. Nicknamed "Neptune's fist" by some researchers (me)

#FossilFriday Holotype specimen of a male Synthethoceras from the Arikaree Group, Nebr. These extinct herbivorous artiodactyls roamed North America for about 40 million yrs. This specimen is amazing; the bone is very soft, yet it survived for over 25 million yrs #NebraskaFossils

#FlashbackFriday and #FossilFriday: I got to see this adorable freshwater muppet-shark (Orthacanthus senckenbergianus) at the @Senckenberg over a year ago. This cute top predator lived in swamps all over Europe and North America until the end of the Permian.

Temnospondyls were poised to be some of the dominant terrestrial vertebrates. If only they could've gotten over that whole not having an amnion thing... Acheloma @FieldMuseum #FossilFriday #temnospondyl

Oooh I’m approaching a milestone 5k followers. Time to bring out the big guns! This is one of my all-time favourite fossils. The ANGRIEST fish you’ll ever see. It had snagged a pterosaur [food = yay] but then tangled together, sunk into the abyss & died – together! #FossilFriday

#FossilFriday: People have debated for decades what the weird, spongy roots on mosasaur teeth are made of. With a little slicing, we figured out that it's the mineralized end of a HUGE ligament that holds each tooth in its socket. *'s show an individual ligament fiber bundle!

A x-section through a fossil tooth of Elephas hysudricus, showing that elephant teeth are funky on the inside. The enamel, dentine and cementum seen here wear at different rates through use, resulting in a series of sharp ridges (lophs), great for grinding plants #FossilFriday

Updating my T. rex model this #FossilFriday to better conform to BHI 3033 scan data (slightly modified from Lautenschlager, 2015). The facial integument has been tweaked, taking cues from @MarkWitton's #SVPCA2018 poster amongst other things. Musculature has also been improved.

It’s time for #FossilFriday! Meet Styracosaurs albertensis. It’s one of the most unusual horned dinosaurs, with a number of large spikes around the edge of the frill and a long nose horn. The ornate frill may have served as an area for the attachment of larger jaw muscles.

Some dancing Ceratosaurus #paleoart for #Fossilfriday. Note complete lippage over their huge teeth: Ceratosaurus jaw bones seem really smooth and lizard like in texture - no indications of weird skin tissues or reduced lips.
