Hello folks, Any ideas on genus/species identification of this humerus? It's 14cm long, hollow, found in Judith River formation, Hill County, Montana. It was identified as "Dromaeosaurid sp. indent" by the seller. Possibly Dromaeosaurus albertensis? It looks very similar to the first museum skeleton below, and fairly similar to the second - although the humeral head is less prominent. However, the morphology in the third and fourth museum Dromaeosaurus examples looks completely different, so I'm not sure what to make of it.

Hey all, While I had my Kem Kem mystery teeth out (i.e., for my post from yesterday), I thought I'd see what you think on this tooth, which I find to be particularly unusual and interesting. Kem Kem is all I've got CH: 14.5mm CBL: 7.3mm CBW: 2.9mm Mesial serration density: about 5/mm Distal serration density: about 3/mm, extremely apically pointed Thank You!

Hello! I bought this dromaeosaur tooth and I’d like to know what genus maybe even species it is from. Thank you! (The tooth measures 0.46 inches and is from hill county Montana it is 74 million years old.

Hello, So I came across this seller offering a “Dromaeosaurus tooth”, and I was wondering if it was properly ID’d. The serrations are pretty worn up front, so I’m unsure. The only locality that I can get is Judith River Formation, Montana. (IIRC, Dromaeosaurus isn’t found in the Judith River Formation.) The dimensions of the tooth are 1.3 inches long, 0.2 inches wide, and 0.1 inches thick. It’s been a little while since I’ve last posted here, because I was busy with life and university. Hopefully I did things correctly.

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.

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

Hey all, What do you think of this toe bone from Hell Creek? The seller marked it as Saurornithelestes with a "?" at the end. It's a tiny 0.5". What I thought might be diagnostic about it is the proximal end. I believe it has Toe 2 Digit 2 characteristics. But it also looks like the flatter top part of the proximal end (bottom part in this picture) may just be worn down or something--it doesn't look totally smooth. If you think there's anything to the Toe 2 Digit 2 hypothesis, then I assume it's theropod indet rather than Saurornithelestes--or is there a case for young

While my prime focus is essentially learning how to accurately describe Nature in the precise language of mathematics, I've always been intrigued by natural history - it's actually what started me on the path to physics. The sort of interrogation that paleontology practices provoked me to think and question even further, down to the fundamental science which makes it all work. Collecting fossils has brought a large amount of enjoyment to my life, and is often a welcome distraction from what can sometimes be straining work. The knowledge that I accumulate along the way is also part

Dromaeosauridae (Cf. Acheroraptor temertyorum) Hell Creek Fm., Carter Co., MT, USA Acheroraptor's dentition is known incompletely, so it's possible this tooth is from Acheroraptor. Until more material is described, this tooth will remain indeterminate. There may be slight facets, but I'm not confident that's what I'm seeing.-

Identification A. temertyorum is characterized by the typical Dromaeosaurid traits (compressed, recurved, differing mc/dc serration densities), and longitudinal ridges/facets on the crown face. Notes This tooth was found this past Summer ('21), and in the same county as the holotype specimen.

I have this tooth that i believe to be a small nanotyrannus but i just want to get confirmation so let me know what you think everyone. Its from the Hell Creek Formation. Garfield Ct. Montana. Its CH is 11 mm Serration count: Distal 12 per 3 mm Mesial 15 per 3 mm The base of this tooth is beat up so its impossible to see if it would have had that rectangular pinch that is characteristic of nano teeth. There seems to be no twist of the mesial carinae In my opinion the serrations look peg like as seen in nano teeth.

I am doing some research on dromaeosaur bones, and I only found limited data and pictures on the web. I am particularly looking for caudal vertebrae and ribs pictures and structures. So I make an attempt towards TFF members knowledge and data !

Identification: This is a typical Dromaeosaurid tooth, with the serrations being differently-sized on each carina; the denticles are much smaller on the mesial carina compared to the distal carina. There's also slight recurvature, which is common in Dromaeosaurs. There are no other features present that allow for identification beyond Family. Described Dromaeosaurs in the Hell Creek Formation include Acheroraptor temertyorum and Dakotaraptor steini. Because both of their known dentitions are incomplete, this tooth may belong to either, or another undescribed Dromaeosaur. Identificati

Hi y'all, I picked up this gorgeous Dromaeosaurid tooth. It was listed as Acheroraptor and I bought it thinking it was one. However, upon receiving it and taking some measurements, I believe it may be a candidate for Dakotaraptor steini, as it virtually matches one in @Troodon's collection in every metric. It has a semi-oval base, with no ridges or facets commonly seen on Acheroraptor. The mesial carina is straight, and terminates almost 1/3 the CH from the base.

Thanks for taking the time to check this out. The vert is ID'ed as Dromaeosaurus from Hell Creek Fm, Powder River County. I've been having a frustrating time trying to make better sense of this, since, as for as I know, there have been no Dromaeosaurus IDs in HC. Are any of you able to shed light on the likelihood of it being dromaeosaurid and anything beyond that? The measurements are 1.875" long * 1" wide * 1.625" tall. (I have a vert centrum ID'ed as Dromaeosaurus from a Judith River Fm and it's only about 0.8" * 0.4*0.5. Position may well explain the huge size difference, but I'm not sure

Found lots of teeth today, here’s some I need a little help with as I’ve never found these before. I think one is a troodontid, one is maybe dromaeosaur, and the other I have no idea. (Apologies for the quality, my phone isn’t good macro photography) Dinosaur Park Fm
