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

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

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.

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

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

Hi all, I could not resist and took another shot on my quest to obtain a Dakotaraptor tooth. Here the tooth in question this time: It was found in the Hell Creek Formation, Garfield County. Measurements are: CH 1,41 cm - CBL 0,68 cm - CBW 0,3 cm - denticles per 5mm are 22 mesial and 19 distal. Note the slight tilt of the denticles towards the tip of the tooth. It's the best fit I have found so far, what deviates from the dePalma description is the shape of the base, it has a pinch, but I would not consider it rectangular. As a side note, it looks exactly like the base of Acheroraptor

Hi everyone, I am currently eyeing this Theropod tooth from the Kem Kem beds in Morocco which is listed as a Deltadromeus tooth. Now I know that no teeth can be attributed to Deltadromeus as no cranial material has been found yet and I know that most teeth sold as Deltadromeus are in fact Abelisaurid teeth but this tooth seems way to curved to be Abelisaurid which could my eye instantly. So I was think if this might be a Dromaeosaurid tooth which while rare (and not yet officially described from Kem Kem) are somethings found and sold as Deltadromeus. Or might this be a small ant

Hi I have had this Hell Creek tooth that was previously ID as Dromaeosaur (possibly Dakota Raptor) for a while and the other day I decided to get my magnifying camera out to take a deeper look at the specimen as I have heard that some Dromaeosaur and small Nanotyranus teeth can be quite challenging to tell apart from one another. These are the close up pics of the specimen that I am still a little unsure about: Mesial side with serration showing a little carinae twist Distal side with straight carinae that stretches down to the base of the tooth in

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.

I found this tiny, slender bone at a Hell Creek microsite during my trip to the Dakotas in 2019 with PaleoProspectors. I'm not sure what it came from, but I'm hoping it's theropod, avian or otherwise. It's missing a section of the outer layer of bone and I believe the interior is hollow & filled in with the ironstone common in the formation. The dimensions are 1.7 cm in length and about 3 mm in width. I would appreciate any feedback you may have. In situ shot from the site: The closeup shots did not come out exactly how I wanted them lighting and detail wise. If you would l

Hi everyone, tonight I want to share with you one of my favorite finds from the summer, this absolutely tiny theropod tooth I found looking through anthill matrix in Wyoming's Lance formation. It's currently the smallest theropod tooth in my collection and it's always an interesting contrast when compared to my largest personally found tooth (a Tyrannosaurid from Judith River). It's about 3 mm in length and a bit over 1.5 mm in width. I believe the serrations have been worn off as they are incredibly faint in some areas and absent in others. I'm not sure if the way the light gleans off t

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!

Dromaeosaurus skull and claw
Jacobloven posted a topic in Is It Real? How to Recognize Fossil Fabrications
Hi everyone! Many of you have probably already seen this piece. The seller says it’s probably a Troodonor or Dromaeosaur and that it’s from an old 80’s collection. I’m interested, what is your opinion on it’s state, the species and restoration? Also, why would they keep the surrounding matrix on the skull? -
I’m hoping that this is a raptor tibia, as it was supposed to be. Can anyone help ID it? Also, I’m guessing that’s filler at the end, there, clearly seen in the 5th, or 2nd-to-last pic? Thanks in advance for any, and all help:)

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?)

Hi!! There's a couple of questions I have that hasn´t been anwsered for too long, and every site that I visit says either contradictory information or doesn´t say anything about this topic at all. Anyway, here it goes. I've been a jurassic park fan for as long as I can remember, and I´ve always wondered if the velociraptor intelligence in the movie was, at least, close to reality. Even if another dromaeosaur like deinonychus had it.Also, In the movie, velociraptor sizes are awfully wrong compered to their real life counterparts. However,I've heard many times that the size of the velo

Hey guys, I have had this claw in my collection for a few months now, I was told that this was a dromaeosaur claw. I wanted to get it looked at by the forum since I’m still just an amateur when it comes to fossils. Was hoping to get some thoughts on it. Thanks!

Could this actually happen in reality?

I was going to wait until tomorrow night to post the 3rd tooth but i got around to taking some pictures and measurements now so here is Unidentified Theropod Tooth #3. Judith River Formation Hill County Montana Crown height 15 mm ( broken base ) Serration count 17 per 5 mm distal 20 per 5 mm mesial I do not see a twist in the mesial carina This tooth is more compressed than the other two teeth the first being dromaeosaurus. Saurornitholestes perhaps?? @Troodon

This is the second unidentified theropod tooth i just recently received. This tooth has a broken tip and its missing most of the mesial serrations. These are the measurements i observed followed by pictures for your own assessment. TOOTH 2 JUDITH RIVER FORMATION HILL COUNTY MT Crown height 12 mm ( missing tip ) Distal serrations are 3 per mm Mesial are 4 per mm There looks like there is a twist in the mesial carina Dromaeosaurus/Tyrannosaur?? @Troodon
