Hi and thanks for taking the time to check this out. I've got a Dakotaraptor prospect from the lance formation, Weston Co, WY. I think the biggest challenge in IDing is the condition of the tooth--particularly the serrations. The specs look good to me and I think there's just enough left of the tooth to have some confidence in the specs being as follows: CH: 19.2mm CW: 10.2mm Mesial serration density: about 5 per MM Distal serration density: about 4 per MM Base cross-section: Almond, no pinch whatsoever Mesial carina: straight and serrations ap

Hi, I think I just got my best candidate for a Dakotaraptor tooth. I'd love to get your thoughts. It's: From the hell creek formation, South Dakota It's about 3/4" at its longest CH: 0.63" CW: 0.34" Mesial serration density: about 5-1/4 per MM Distal serration density: about 4-1/2 per MM Serration shape: looks "raptor" to me--or at least unusually long, thin, and rounded for a tyrannosaurid Base cross-section: Almond, no pinch whatsoever Mesial carina: straight as an arrow, serrations ending about 2/3 of the way do

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 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. Dromaeosauridae Hell Creek Fm., Carter Co., MT, USA CH: ~ 10.5 mm CBL: ~ 6 mm CBW: 3 mm Mesial de

Trying to differentiate a small to midsize Nanotyrannus and Dakotaraptor is pretty difficult. It appears that Dakotaraptor teeth are not common and sellers are quick to assign Nanotyrannus teeth to them. You need to look at all the characteristics before making a determination on a tooth and it may turn out to be indeterminate. REMINDER we have a limited view of these teeth. We have not see a complete dentition and most likely there some variations in dental positions. What is listed below is our current knowledge based on isolated teeth and the few found with the holo

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 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

Hi everyone! I have a large claw from the Hell Creek Formation of Harding County, South Dakota that I was hoping to have help identifying. It is large enough that I initially believed it stood a chance at being tyrannosaurid, but it seems a bit more compressed than tyrannosaur claws I’ve worked with in the past - particularly on the lower ridge. The ventral surface of the claw is also distinctly flat rather than rounded, which seems unusual. Could this be a Dakotaraptor claw or is that just wishful thinking? Large Anzu perhaps? It is right around 1.75 inches across the length of the claw (sorr

Merry Christmas! I see this tooth in a fossil website. The tooth have been sold, but i found it very interest. It is possible to be a Dakotaraptor or other dromaeosaurid tooth? Also the price was very good for a so rare and nice specimen.

Hi everyone, I just got this tooth from the Hell Creek Formation of Carter County, Montana. It was labeled as Richardoestesia, so based on the curvature, I was assuming the proper ID would be cf Richardoestesia gilmorei. However, when taking some measurements, what caught my eye was that the mesial carina appeared to end 1/3 from the base, and I started to wonder if instead this tooth could possibly be Dakotaraptor. These are the measurements I was able to get: Mesial: around 5.5-6 serrations/mm Distal: around 5 serrations/mm CH: around 16.5 mm CBL: aroun

Hi all, I could not resist and purchased this tooth knowing it would be a tough call to make. It was found in the Hell Creek Fm. The big problem is the worn down mesial carina, there are however some remnant denticles I could measure, but not midline – more posterior. Taking them into consideration the tooth has distal 4.5 denticles per mm and mesial 6 per mm. The other measurements are: CH 1.47 cm / CBL 0.74 cm / CBW 0.39 cm. Based on this and the oval base I am leaning towards Dakotaraptor but might as well be a specific T-Rex tooth position.? I really need someone more experienced to take a

Whats up all! I havnt posted in a while mainly due to just having everything all over the place since we've moved back into our house after a long time away due to renovation. I still have a ton of fossils in my collection and alot of unidentified teeth that im going to try and post on here more often.....ill be posting 2 tonight with the first being this tooth here : Its from the Hell Creek Formation, Tooth Draw Quarry , NE Butte County, South Dakota. Its CH is 13 mm The CBL is 8.5 mm Distal serration count is 3 / mm Mesial serration count is 4 / mm

This next tooth im posting is another one from the Hell Creek Formation. It was found in the Tooth Draw Quarry in Butte County South Dakota. Its CH is 14.5 mm CL is 5.5 mm Its got a round base I wish i could give you a serration count but there arent any so this may be a tough one. Paronychodon maybe? Give it your best guess! @Troodon

Hi all, I posted this tooth for ID a while back. Conclusion was that it could be a Dakotaraptor, maybe, maybe. Since then I am going back and forth on the ID, basically on a daily basis So I decided to take more & new images, measure it thoroughly, put it up again, and kindly ask for your help. It was found in the Hell Creek Fm, Powder River Co., Montana. Measurements are: CH: 2.08cm CBL: 0.8cm CBW: 0.42cm Serration count per 5mm is mesial 24 and distal 18. What makes it hard for me to judge: the shape of denticles is between round and chisel (?), the tiny mesial denticles,

This next tooth i just recently purchased was sold to me as a probable dakotaraptor tooth. Its from the hell creek formation in Powder River Co. MT. Its CH is 18 1/2 mm....posterior serrations are 20 per 5 mm. Anterior serrations are 25 per 5 mm. @Troodon , @Andy, @fossilsonwheels

This next tooth was listed as a possible dakotaraptor steini...what do you guys think? Sorry for the finger placement in some of the pictures.....from the hell creek formation in powder river co. , MT. The size is 15/16 " and Serrations on the posterior of the tooth are 5 per mm and 10 per 2 mm. The anterior serrations look smaller and look to be about 6 per mm.... @Troodon

Hey everyone, I recently came across this fossil online. It was listed as a metatarsal joint fragment, which to me checks out, but the person further identified it as a Dromaeosaurid [though they didn't specify based on what characters] and tentatively assigned it to Dakotaraptor based on size. Now I was wondering: Can remains this fragmental even be reliably distinguished from the other small- to medium-sized theropods in Hell Creek? The fossil was found in Hell Creek deposits in Wyoming [no info on the exact location], measures 30.9 x 27.5mm [not specified along which sides], and

This is being sold as a dakotaraptor claw from the Hell Creek Formation of South Dakota. How does it look and could someone please tell me where on the dinosaur this claw belonged? It measures 7 by 4 by 15mm. Thanks in advance.

A totally AWESOME addition to our dinosaur collection
fossilsonwheels posted a topic in Member Collections
I recently added a Dromaeosaurid vertebra to our collection. I honestly did not bother with specs once I got it confirmed as Dromaeosaurid. I never asked size or what formation. I assumed it was from Judith River because it was sold as Dromaeosaurus. i knew it was going to be Dromaeosaurid indet so I was not worried about the specific ID. It is a raptor fossil so I wanted it. The vertebra arrived today and I got two very pleasant surprises. It is bigger than I thought. It is also not from Judith River or the species known from that formation. We got a Dromaeosaurid vertebra from th- 4 replies

I just saw this tooth listed as Dakotaraptor. It's 3/4" long. Most of these "Dakotaraptor" teeth I see just scream Nanotyrannus, but I'm not so sure on this one. I looked at my Acheroraptor and Nanotyrannus teeth and the distal serrations look a bit more like those of Acheroraptor - especially those near the base. Unfortunately, the mesial serrations are all worn off. What do you guys think?

Is this tooth dakotaraptor or nano?
Captcrunch227 posted a topic in Is It Real? How to Recognize Fossil Fabrications
Hello all. Seller has this labeled as a dakotaraptor tooth. After hours of my own research and still being unable to come to a clear conclusion I decided to post here for help. Troodons guide helped a great deal but I still couldn't be positive. Any help is greatly appreciated. -
Hello everyone, I'm new here! Are there anyone who can identify these teeth? The shop says they are dromaeosaurid, but I think these might be from Nanotyrannus. Their crown morph clearly not Acheroraptor. Many thanks in advance!

Hi all, I am new to the forum and new to collecting =) I recently obtained this nice tooth labeled as Dromaeosaur sp. premax. tooth - I would like to get a more refined ID if possible. It was found in the Hell Creek Fm., Powder River Co., Montana and measures 15/16". Denticle count per 5mm is distal 18, mesial 24 (not many denticles visible mesial though). I found a thread here stating it is possible to distinguish Nanotyrannus from Dakotaraptor teeth by the shape of the denticles - however I find this very hard as rookie. Any help is appreciated!
