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.

Montana State Museum of the Rockies - July 2021
AlexSciChannel posted a topic in A Trip to the Museum
So over the past few days I was visiting Bozeman from Raleigh North Carolina as I was visiting the MSU campus because I've been accepted to start as a freshman in autumn 2021. And I hope you know what I am trying to major in. I mean you know what forum we're on I don't have to spell it out. Anyway, in that time I managed to spend all day visiting the Museum of the Rockies which is considered one of the Mecca halls for paleontology. Our crazy old boi Jack used to be Prof and curator there before... well you know. My home museum, the NC Museum of Natural Sciences are taxonomic lumpers when it comes to paleontology but they are passive lumpers. They are nothing compared to what the MOR has going on holy snarge I was surprised. I like going to different museums like this because it shows different perspectives based on findings that vary by institution. While I don't agree with a lot of it, it's healthy to expose oneself to different ideas and conclusions. Also I just couldn't help but feel giddy in the midst of all these dinosaurs. I'll update this post with pictures in a few moments... I will also post what the info cards on the exhibits state about each specimen. Here is Big Mike. A metal replica of MOR 555 commonly known as the Wankel although now more known as the Nation's T. rex since the og skeleton's move to the Smithsonian. I spent at least 30 minutes admiring the sculpt of this beautiful beast alone. Our first is a tibia of a Hadrosaur indet. found in 80 mya rock in Chotaeu, Montana so likely the Two Medicine Formation however this is unique because this is from it's lower strata which we don't know much about that's why it isn't identified as Maiasaura, as that dinosaur lived later. Here are some nice trace fossils and geology stuff, Here's the Precambrian globe Here's how sediments move through time. There's dioramas too. Starting with the Cambrian of course with Anomalocaris and working our way up. Here we're getting some Ordivician and Silurian description, Devonian like creatures. Although Coelocanths first evolved 400 mya they live all the way up to the present day. Stethocanthus below Next we start going in depth into the dinosaurs more updates coming stay tuned...- 17 replies
