From the album: Dinosaurs
A theropod tooth I recently acquired from the JRF. Sold as a juvenile Tyrannosaurid, but I'm not fully convinced. -
As a follow up to my last topic, i've included some of the other dinosaur teeth that I acquired at an annual fossil show. The first tooth pictured is claimed to be Triceratops, no locality was included but he claims it was found in North Carolina. however I cannot find any information to which Triceratops material has been found in NC. The second tooth pictured is claimed to be a Leptoceratops tooth from Hell Creek, however it seems they are often misidentified as Triceratops teeth. The third tooth depicted is Labeled as Richardoestesia, also from the Hell Creek formation. I am gra

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

I'd found this partial tooth in some lance fm matrix. It doesn't look like crocodile so I think that it might be Richardoestesia. Here are the pictures. It's about a half inch long.

Is this a Two Medicine juvenile tyrannosaurid or Richardoestesia tooth?
-Andy- posted a topic in Fossil ID
Hello, this tooth has baffled me for years. I can't tell if it is a juvenile tyrannosaurid dentary tooth or a cf. Richardoestesia gilmorei tooth Its locality info is Montana, Two Medicine Formation The tooth has a serration density of 19/5mm on the distal mid-line. Unfortunately the mesial carina is worn down so that crucial data is missing The CH is 11.5 mm, CBW is 7 mm and CBL is 4.5 mm As far as I am aware, juvenile tyrannosaurid (with the exception of T. rex) have slender teeth while as this tooth is somewhat robust. Meanwhile, Richardoestesi- 2 replies

What Is The Complete List Of Dinosaur Species Known From Hell Creek, Including Tooth Taxons And Synonymous Species?
Mioplosus_Lover24 posted a topic in Questions & Answers
I have yet to see a conclusive list of EVERY dinosaur known from the Hell Creek Formation, I am curious if anyone has one or knows all the dinosaurs, thank you! -
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

Good evening, today was THE day for me. In our city was the annual fair with fossils on offer. I was out and looking for uncommon/rare dino teeth and was lucky to find some. I know that most of the ID done by the sellers is wrong I would like to show my new aqusitions to you throughout the next days and hope for your help. No. 1 was sold as an "Richardoestesia gilmorei" from the Hell Creek Formation, Wyoming, USA (unfortunately no county provided). Length: 18mm Width (base) 6mm denticle count: Side 1: 6 per 1mm Side 2:

This is an interesting tooth. It is from the Hell Creek Formation. no county was given only Montana. It is .3 cm and is serrated. It has a very interesting shape to it which i thought was similar to bird teeth but after seeing the serrations, my thought was Richardoestesia gilmorei. I am probably way off in my thinking. At the very least, I thought it was interesting enough to post here and see what other opinions are. Any thoughts ?

I have recently acquired a nice Richardoestesia tooth from Hell Creek. I suppose it's R. isosceles. I decided to read more about this species, and felt really confused. Why is it even considered a dromaeosaur?? As far as I know, dromaeosaur teeth are not only usually smaller and strongly distally recurved, but also have no or very fine serrations on the mesial side and coarse serrations on the distal side. Richardoestesia teeth I've seen lack all of these characteristics: they have identical very fine serrations, straight and relatively large crowns. Actually, such teeth remind me a

Is this a tooth of Richardoestesia isosceles? Scale marks on left side of tooth are in mm and on the right side are in 0.5 mm increments. Serration count ranges from about 6 to 8 per mm. What remains of the tooth is approximately 11 mm in length. Hell Creek Formation (Late Cretaceous: Maastrichtian), South Dakota.
