Gonzalez Abstract :: was a successful clade of , spanning the Late period to at least the Late period, but their fossils are scant outside and Cretaceous records are controversial. Here we report, to our knowledge, the first cranium of a large haramiyidan from the basal Cretaceous of North America. This cranium possesses an amalgam of stem mammaliaform plesiomorphies and crown apomorphies. Moreover, it shows dental traits that are diagnostic of isolated teeth of supposed multituberculate affinities from the Cretaceous of , which have been assigned to the enigmatic ‘’. Exceptional preservation of this specimen also provides insights into the of the ancestral mammalian brain. We demonstrate the haramiyidan affinities of hahnodontid teeth, removing them from multituberculates, and suggest that hahnodontid mammaliaforms had a much wider, possibly Pangaean distribution during the Jurassic–Cretaceous transition.

@britgeosurvey • • • For #FossilFriday we have an archive photo taken in 1906 from Storeton Quarry, near Birkenhead, Wirral. The picture shows fossilised footprints from a Triassic reptile named Chirotherium and is just one example of many that were found in the quarry in the 19th century.

Possibly the most incredible fossils I’ve ever seen! Silicified insects from the Miocene (~14 million year old) Barstow Formation in California. Housed at @fossilsofla, @nhmla, thanks to @katyfossillady for showing us these amazing specimens. #fossilfriday

Today's #FossilFriday is also a to 2013 when our WitmerLab team presented our NSF-funded Visible Interactive Dinosaur project—at least in the little talk that I’m giving in this photo—at a rural Appalachian public library here in our own town of Athens, OH. We took dozens of skulls and set them up around the library and then turned the kids loose on them. Other than the little talk I gave, our team circulated around, informally discussing with the kids and their families lots of things about science that dinosaurs can illustrate.

Its Fossil Friday Above are two fascinating Septarian Nodules - Formed during the Cretaceous period, around 50 - 70 million years ago due to periodic volcanic eruptions that killed smaller sea life. The carcasses sank to the sea bed and started decomposing whilst also attracting sea floor sediments which attached to the carcasses forming the nodules you see before you. The mud balls eventually dried out as the water receded and beautiful patterns began to show. For a closer look at these incredible specimens come visit us in our Banff and Whistler Locations.

I wanted to climb on the dinosaur and take a picture for #fossilfriday, but I’m wearing a skirt, I’m clumsy, and this metal beast is almost the temperature of the sun.

friday or maybe ———————— I received this specimen as a gift. It went up in my office and I always thought it looked weird, but never really checked it out. Well today I did and it’s known as a ‘Composite Plate’, basically real fossil fragments in a fake arrangement. In this case the “Orthoceras” are different segments lined up to look like large complete individuals. The Goniatite ammonite seems to be complete. However all three have been attached to this solid slab. You can see on the back of the slab the nautilods are cross sectioned, not longitudinally sectioned. This is a common occurrence with fossils from Morocco. I’m assuming it’s from Devonian aged outcrops in the Anti-Atlas region. Although is a composite I still think it’s aesthetically pleasing and it’s a great conversation/teaching piece. ⚒ . . .

It’s #fossilfriday and we had a fun visit from our friends at the @westernsciencecenter today. Max the Mastadon (and his caretakers Alton and @brittandbone) loved our Ephippiorthoceras, an Ordovician nautilus. These long, straight, shelled cephalopods dominated in a sea without fish and could grow to about 30 feet long! Giant Eurypterid in the back for scale 🦂

🦖 I’d like to thank @universalpictures, @prattprattpratt, and the rest of the cast and crew of for donating the carcass of Indoraptor after production wrapped. This animal will be a huge draw to our museum for both the general public and scientists. It will be especially fascinating for those paleontologists studying the absence of feathers. #fossilfriday 🦖

Happy friday! So in my stories I asked if you thought this was a plant or animal. . 70% of you voted for animals and you all are right! It may not look like it, but is an animal. It’s a crinoid to be more precise! . Crinoids are a kind of echinoderm (means spiny skin) and are related to animals like sea stars and sea urchins. . Now if you chose plant, that’s understandable. Crinoids do look a little like plants. They have a stalk and their body and arms look like a flower. What we are looking at in this picture is the holdfast, the end of a crinoid stalk that keeps them anchored to the sea floor. . . . friday

Happy #FossilFriday ! Saw great displays & collections @museumofnaz yesterday in Flagstaff, removed a giant phytosaur skull with @petrifiedforestnps & excavated a lot of bone, like this aetosaur osteoderm. Been a productive week!

friday!! So this was one of the biggest highlights from this week at the quarry: an Allosaurus premaxillary tooth! This 3.5cm monster has some nicely preserved serrations that help to identify it as a premaxillary tooth. Allosaurus is the state fossil of so I feel like this is an appropriate homage for the first week in the quarry!

This week's friday is brought to you by the interpretive staff at . This weird rock is an ironstone nodule with a bivalve shell fossil (mussel) at its core. Coolest geode ever! Come visit us at Dinosaur Provincial Park and maybe you too can find a cool fossil like this one! . .
