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.

From the album: Hell Creek / Lance Formations
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: 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. Identification further discussed here. Notes: CH: ~ 10.5 mm CBL: ~ 6 mm CBW: 3 mm Mesial denticle density: 8 / mm Distal denticle density: 4.5 / mm There is some minimal feeding wear on the tip, but this tooth is otherwise flawless.

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.
