Fast. Intelligent. Deadly. The "Raptor" is perhaps one of the most famous dinosaur today thanks to Jurassic Park. To many people's surprise however, raptors are heavily feathered and nimbler than movies would have you believe. The Jurassic Park Velociraptor was merely the size of coyote in real life! In fact, their proper family name is 'Dromaeosaurid'. The largest species was Utahraptor, and it grew to the size of a grizzly bear! Dromaeosaurid fossils have been found all over the world. They first appeared during the Cretaceous, though isolated teeth have been found in the mid-Jurassic. Allow me to present my humble collection of Dromaeosaurid teeth. First up, from Cloverly Formation, one of my pride and joy from @hxmendoza A dromaeosaurid from Aguja Formation. I am seeing more Aguja fossils showing up, but dromaeosaurid teeth are still rare. Now, for the dromaeosaurids from the famous Hell Creek Formation. Some of them probably lived alongside T. rex. A big shout-out for @Troodon for getting me started on dromaeosaurids with this very first Acheroraptor!

I found this small theropod tooth (missing the tip) in the Horseshoe Canyon Formation of Alberta a few months ago. I’m not sure on the identity of the tooth, as it’s rather Troodontid or Dromaeosaurid. It has the crown and denticle shape of a troodontid, but the serration density of a dromaeosaurid (about 3 serrations per mm). The serrations are a bit worn down fyi. Any help would be greatly appreciated, thanks!

Hi everyone, I purchased this tooth from the Horseshoe Canyon Formation in Canada recently and was wondering what you guys think of it. The seller sold it to me as Theropod indet, but said he believes it to be Atrociraptor Marshalli. What troubles me is the lack of serrations which might just be worn down. Tooth is 1.2 cm long and originated from the Horseshoe Canyon Formation in Canada.

Building the Dinosaur Program- Horseshoe Canyon

I am super excited to say we are adding a couple of fossils from Canada. Part of working on getting a 501c3 is making sure we operate within our own bi laws and working with any laws that govern whatever it is you do in your non profit. I saw a dealer with some Canadian fossils from the Horseshoe Canyon formation that came with a disposition from the Canadian government. I saw an opportunity to grab a few fossils that not only add something to our presentations but gave us legally obtained fossils from our neighbors to the north. The dealer was kind enough to work with us on holding a couple of items that were within our budget. There are some really interesting dinosaurs in Horseshoe Canyon and while we did not add anything rare or spectacular, I am quite happy with what we did pick up. We got our Ankylosaurus scute. We had been looking to pick one up and we were not finding anything affordable. Not only is the one we picked up from Horseshoe Canyon, it was quite affordable for us. I am not yet sure which Anky we will talk about in our program but either way this was a great addition. I think it compliments our "Zuul" tooth very nicely and the kids will really like seeing some of that Anky armor. We also picked up a toe bone from a Ceratopsian. The kids really liked learning about animals other than Triceratops so I jumped at the chance to add one from this formation. Like the Anky scute, the genus and species is indet but I am pretty sure we will talk about Pachyrhinosaurus when we show this fossil. It is a cool critter with a cool name. We talk a lot about Ceratopsians so this was an easy choice. We also added something really cool. We got a Dromaeosaurid tooth. When I purchased it, the seller had said it was from Judith River and labeled it as Dromaeosaurus albertensis. It is not from Judith River. It was actually collected from Red Deer River Badlands near Drumheller in Alberta. I am pretty sure it is actually from Horseshoe Canyon which means it is not Dromaeosaurus. The only described raptor from that formation is Atrociraptor. I will get around to posting better pictures and seeking an ID from TFF members eventually but for now am quite good with going with Atrociraptor for education programs. It was a pretty fearsome looking creature and also pretty different from the other raptors we present. Sure, I whiffed on Dromaeosaurus again but I am not complaining. It is another really nice tooth and we add another dinosaur to educate the kiddos about. This also gives us a theropod from the formation which rounds out the presentation nicely. I am pretty sure the tooth is also legal as it was collected in the 60's and has been in the US since the 70's. Anyway, here are the fossils minus the toe bone which I do not have a picture of yet.- 2 replies

I have been looking for an Atrociraptor marshalli tooth for quite awhile. I happened to find someone who had one and he was nice enough to sell it to me, along with a French dromaeosaurid tooth. I got them both in the mail today. Thank you to the seller, who’s a TFF member!
