Giant Dromaeosaurs and other Eumaniraptora from the Cretaceous period
Joseph Fossil posted a topic in Questions & Answers
The Eumaniraptora is a clade of non-avian theropod dinosaurs that first emerged during the late Jurassic period and diversified extensively during the subsequent Cretaceous period (143-66 Million years ago). This group is most famously known as the Raptor dinosaurs (the sister clade of the theropod dinosaurs that gave direct rise to the birds), consisting of mostly small to mid sized theropod dinosaurs. There are a few species though that exceed the typical small-medium size range for the raptor dinosaurs. Only a few giant raptor dinosaurs are currently known. But recent discoveries over the p- 1 reply

Identification Troodontid teeth may be identified by their exaggerated, triangular, apically directed posterior denticles1. Pectinodon bakkeri is the only Troodontid species currently named from Lancian strata; its teeth are on average smaller and more gracile than those of its cousin, Troodon. Comments Pectinodon (meaning "comb-tooth")1 is a tooth taxon, since no remains attributable to the genus beyond teeth have been found. Pectinodon seems to be a rare member of the Hell Creek fauna, with their teeth being fairly uncommon. It was a small theropod, with teeth that couldn't ha

Hello, friends, I want to determine the species of this claw from Iren formation, Inner Mongolia? I know that there are oviraptor and potential Troodon in Iren formation. I think it most likely belongs to one of both? I really appreciate if someone can give me some clues.

Pectinodon (meaning "comb-tooth") is a tooth taxon, since no remains attributable to the genus beyond teeth have been found. Pectinodon seems to be a rare member of the Hell Creek fauna, with their teeth being fairly uncommon (though being so small, I'd guess that few people actively search for them). It was a small Troodontid theropod, with teeth that couldn't handle stresses as well as their Dromaeosaurid and Tyrannosaurid cousins (Torices et al. (2018)). This coupled with their small size suggest that Pectinodon was a small/soft prey specialist, preferring the rodent-sized mammals of the ti-

Even in the final years of the non-avian dinosaurs, the paravians remained diverse, with many species represented in the famed Hell Creek formation. -
Hi everyone! I wanted to post one of my new favorite finds from this past week of collecting in the Hell Creek formation of Montana. I found this little partial claw at a microsite which proved to be quite productive, making for a great day. While the articulating surface is missing, I still feel that it could be identifiable and my first guess is bird. Avisaurus in particular as I remember seeing similar claws being labeled as such on other platforms. It’s about two centimeters long and the bottom is flat, giving it a somewhat triangular cross section. photos from the field.

Hi all, This small 5/32" tooth came from Powder River, Hell Creek, Montana. The thought was that it's Saurornitholestes, but it comes off to me as having a awfully troodontid ind. look, no? It looks very curved for Saurornitholestes. The distal denticles seem like a big fit for a Saurornitholestes tooth (but maybe the tininess of it is throwing off my sense of scale) and, while the distal denticles look like they're significantly worn, it looks a little to me like they point upward throughout the CH (as opposed to only the denticles towards the tip pointing upward). I would think t

Hi everyone. Tonight I'd Iike to share my most recent find: an absolutely tiny theropod tooth I found late at night sorting through what remains of the Aguja fm. matrix I purchased last year. I knew it would pay to be thorough and I was delighted to see the glint of enamel in a triangular shape eventually appear. Additionally, it has just taken the crown (no pun intended) for smallest theropod tooth in my collection, at only 2 mm in length and just over 1 mm in width. I'd be interested in reading your opinions on it's identity, I'm thinking either dromaeosaur or troodontid but I'm not sure.

Hey guys! My first scientific publication has just been released online by the journal Geological Magazine in association with Cambridge University Press (see link below). My study describes the first probable deinonychosaur tracks from Canada, which my colleagues and I found and documented at a large dinosaur tracksite (about 72.5 million years old) near the city of Grande Prairie in Alberta, Canada. Four traces occur in possible trackway association, while another isolated track that is in exactly the same direction is located nearby on the same bedding plane, suggestive of at least tw

A new genus of Troodontid has been described from late Maastrichtian fluvial deposits of Spain's Talarn formation (Tremp Group). It was named Tammaro insperatus named for a small, elusive creature from local folklore and the latin word for unexpected due to where it was found. Very interesting to see this family of dinosaurs officially represented in Europe's fossil record, along with the overall diversity on the continent when it was still archipelagic. https://www.nature.com/articles/s41598-021-83745-5 http://www.sci-news.com/paleontology/tamarro-insperatus-09426.htm

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!

We have been working primarily on our shark program material but we did add a few new dinosaur fossils. For the most part they are pretty small in size but add quite a bit to the education we do. These represent some iconic and scientifically important dinosaurs. In addition to these small fossils, we added a 6" Trike frill piece from HC, a smaller piece of a Horseshoe Canyon Ceratopsian frill, and a 2.5" Hadro vert from that formation. These are excellent touch fossils so I am happy ! The small fossils are..... Dromaeosaurus sp. Judith River. I big thank you tha
