Triceratops horridus (or prorsus) (Marsh, 1889 /1890) Late Cretaceous, c. 67 Ma Hell Creek Formation, Powder River Co., Montana After acquiring a gorgeous T. rex tooth, I could not resist the opportunity of acquiring a tooth of its likely prey - Triceratops. I’m aware of the difficulty in identifying ceratopsian teeth and the impossibility of distinguishing between T. horridus and T. prorus. As Triceratops is the most commonly encountered genus within the HCF, this is labelled as being Triceratops horridus or prorus in my collection. I understand that the locality is known for T. prorus so it may well be that this is T. prorus. I love this specimen for it still having the root - so unlikely to be a shed tooth.

A rooted Ceratopsid tooth - either Triceratops or Torosaurus (though it's more likely to be Triceratops since it was far more abundant in the HC ecosystem). -

Plant roots often intrude upon a fossil's resting place, leaving behind white streaks when removed. -

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), only association with an identifiable skull can allow for identification beyond Ceratopsidae indet.

Identification: 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.[2], 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), only association with an identifiable skull can allow for identification beyond Ceratopsidae indet. Notes: This tooth is partially rooted with noticeable feeding wear on the crown (the flattened surface). It has some minor repair. The second image shows a close view of the enamel, which has good preservation. Relevant Literature: 1. MARSH, OTHNIEL C., 1889. Notice of gigantic horned Dinosauria from the Cretaceous.

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 being from T. prorsus. -
