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

Not mine - belongs to a university. I want to say it is about 3 inches in length. I cannot remember exactly where it was found, but I do know it was an isolated tooth found in Texas. Quite a rare and awesome tooth to see in person. -

Edmontosaurus annectens Hell Creek Fm., Harding Co., SD, USA Partial dental battery Hadrosaurs had the most histologically complex teeth of any animal, with six unique tissues. This allowed for differential wear, creating an ideal coarse surface for grinding plant matter. (Erickson et al. (2012)) -

I just got another possible Judith River shed tooth out of a different piece of matrix. While in the matrix ceratopsian was suggested. I’m hoping it’s not a pebble this time. Just over a quarter inch in length

Hello all, I need some help ID'ing these two tyrannosaur teeth from the Two Medicine Formation in Montana. Does anyone know how to tell the difference between Gorgosaurus and Daspletosaurus teeth based on this size? Thanks for any help.

I got this tooth from the soil which was brought from the mountain to our house.

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. Identificati

Triceratops prorsus Hell Creek Fm., Harding Co., SD, USA 3.5 cm height On the ranch where this tooth was found, only T. prorsus skulls have been found in the 30+ years the company has operated there, lending a very probable, precise identification for this Ceratopsian tooth. (T. prorsus was one of the last dinosaurs, younger than T. horridus. The two species are also stratigraphically separated in the Hell Creek Fm., so it makes sense that one may only find one species in a particular deposit.) For most Ceratopsid teeth (from the Hell Creek Fm., for example),-

Triceratops prorsus Hell Creek Fm., Harding Co., SD, USA This is a nice tooth with great enamel, partially rooted, and has some feeding wear (which I enjoy). It does have some repair/consolidation. Usually, Ceratopsian teeth are indistinguishable from each other. In HC, Torosaurus and Triceratops (currently) are the valid genera. However, the company operating on the ranch where this tooth was found has only found T. prorsus skulls in the 30+ years they've been there. This tooth, being found in the same deposit, therefore has a good probability of bein -
