Hello! I am student of the biological sciences with an intended minor in geology. I have been collecting fossils for a long time, and am excited to join the forum! I just purchased my first "dinosaur" specimen from an annual fossil show. My collection and interest has always been in Paleozoic invertebrates, so my dinosaur knowledge is extremely limited. The seller said the species was of the Dromaeosaurus genus and the origin was from the well known Hell Creek formation, however I took everything he said with a grain of salt. After reading some previous posts on the forum i've seen that it may be from morocco, and henceforth not part of the Dromaeosaurus genus. The length of the tooth is exactly 1/2 an inch in length. I've included some photos below of the exact condition in which it was sold to me. I know identification from a single tooth can be difficult, so I'm grateful for any information that can be provided on the specimen! Please let me know if more adequate photos need to be provided, I have several microscopes in my collection that could get a closer view of the serrations.

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 the attribute that most makes troodontid ind. questionable is the high density of the mesial denticles . But I thought I'd heard (even if just in TFF wisedom) that there's significant variability in the mesial denticles of troodontid from this area--even to the point of there being none, potentially (?). What do you think? Thanks!!
