Hi TFF, I am a Dromaeosauridae enthusiast and have been collecting online for a little while now. I want to thank the members here for getting me educated on so many aspects of fossil teeth identification. I want to share my small collection in the hopes this is helpful for some of you in the future. Your critical input is highly appreciated, as always! #1 First up, one of my treasures, a robust Deinonychus antirrhopus tooth from the Cloverly Fm. A big thanks to @StevenJD for letting go of this one – much appreciated! Note the asymmetry in the placement of the carinae

Hello and thank you for checking this out. I got this tooth a while back. It comes from the Judith River Formation and is about 8mm apical length. The serrations seem large to the tune of Troodon, but they're too worn to be certain that they point apically throughout the posterior carina. (It was sold as Pectinodon, but I'm not seeing that.) What do you think it is? Thanks!

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

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

Identification: Dromaeosaurs have differently-sized serrations on each carina, the ones on the distal carina being much larger and pronounced than the mesial ones. The mesial carina also has a classic twist. Notes: This tooth has feeding wear facets on both the labial and lingual sides of the tip. Citation: SUES, HANS-DIETER, 1978.

Howdy! This is a dromaeosaur tooth from the upper Dinosaur Park Formation. I’m pretty sure it’s Saurornitholestes, but based on the size (1cm L) and shape, is it possible to tell the position in the mouth? (Ex maxilla, dentary, predentary?)

Fossil Hunting From The Safety Of Your Home
Mioplosus_Lover24 posted a topic in Fossil Hunting Trips
With the current pandemic I decided now was as good of a time as any to get some matrix from the Aguja Formation with the help of PaleoTex! This turned out to be a great decision as I was extremely lucky, finding about basically everything I wanted to, and more in only 5 pounds of matrix! I'll be sure to post pictures but I got numerous amia and gar teeth, along with atleast 36 gar scales. Tons of Crocodile teeth including a large Deinosuchus tooth. Several shark teeth and a partial hybodus spine, also several brackish water pycnodontid teeth and tooth pallets. 4 fish or salamander jaws with t- 64 replies

I recently picked up this tooth labeled as dromaeosaur from the Judith River Fm in Hill Co, MT and I think it may be Saurornitholestes langstoni. Can anyone confirm the id for me? Thanks!

Hey everyone i hope you all had a great holiday season....this next tooth in my collection was labled saurornitholestes from the hell creek formation from powder county MT. We know that the only two described raptors from there are dakotaraptor and acheroraptor so im curious to see what you all think of this one. Nanotyrannus perhaps? Unfortunately the anterior serrations have worn off which im sure will make id'ing this tooth difficult but anyway here it is. ....the CH is 9 mm the posterior serrations are 12 per 3 mm. @Troodon

Next up in my collection is this one that was sold to me as a possible saurornitholestes langstoni tooth. From the Judith River Formation in Wheatland Co. MT. CH is 9 mm. Serrations are 15 per 3 mm on the posterior of the tooth and 23 per 3 mm on the anterior of the tooth. @Troodon

Seeking some scientific information about Judith River dromaeosaurids
fossilsonwheels posted a topic in General Fossil Discussion
I was hoping somebody on TFF might be able to point me in the direction of any scientific papers, research or information that members here might have put together regarding dromaeosaurid theropods from the Judith River formation. This is not really about identifying any teeth, though I do have one from that formation. I am starting to do my research for the education program and am looking for scientific information. From what I can gather, there is a possible Saurornitholestes species and of course the dinosaur I have seen referred to as Julieraptor, which is a interesting story -
David Evans who described Acheroraptor shared this photo and information on a few notable Dromaeosaurid's. Thought it would be of interest to the Dino guys and others. I also show a hand next to an adult Velociraptor skull which gives a real life size comparison, since a lot of depictions and replicas sold are well oversized. Acherorapter is from the Maastrichtian of Hell Creek/Lance Formation Saurornitholestes shown from Campanian of Canada/Montana Velociraptor from Campanian of Asia David: How big was the Hell Creek dromaeosaurid Acheroraptor temertyorum
