Hi All, I'm new to this forum and thought I'd send over images of my theropod teeth plus one extremely impressive sauropod from Madagascar. Hope you like them! Paul

From the album: Hell Creek / Lance Formations
A replica of a large T. rex pes ungual, about 7" in its largest dimension. -
Of all of my fossils this is the one i'm most sceptical about. I bought this as a bone but compared to other specimens I have it is not the spongy texture very often seen on bones. It was labeled as t rex so it is from the Hell creek FM. It does smell as a fossil tho.. Any help will be appriciated.

A few of the dinosaurs present in the HCF, as represented by their teeth. These fossils mostly come from Montana and South Dakota. Most are self-collected, others were purchased. Silhouettes taken from Liam Elward, Fred Wierum, and PNSO. -
From the album: Hell Creek Formation Microsite
Typical fragments of T. rex teeth. A) my largest fragment thus far, with a portion of the anterior carina and root; B) tip of a large tooth with feeding wear - the bottom exhibits a spiral fracture, perhaps it broke off with a twisting motion; C) premaxillary tooth of a young juvenile tyrannosaurid. -

Not sure why, but I could look at serrations all day - little marvels of natural selection. And to imagine 66 million years ago these were cutting through dinosaur muscle fibers! -

From the album: Hell Creek Formation Microsite
This tooth saw some action - a wear facet (caused by repeated opposing tooth-tooth contact), gouges in the enamel, and completely worn serrations (after the hard enamel wore away, continued use and softer dentine led to depressions where protruding denticles once were). -
From the album: Hell Creek Formation Microsite
This fun family photo emphasizes how ridiculously outsized T. rex was - the tip of a tooth is larger than entire teeth of contemporaneous theropods! T. rex was a highly unusual animal, especially in the context of its own ecosystem. -
From the album: Hell Creek Formation Microsite
A posteriorly-positioned tooth from a juvenile animal. Overall a decent tooth with some evidence of river wear - smoothing at the base (which is softer than the enameled crown), and enamel pitting from corrosion. -

1 inch tooth. Seller says it’s a T. Rex tooth, from what I’ve seen the T. rex teeth are more robust this one looks narrow but I’m not sure. From hell creek

Location: Hell Creek formation, Carter county Very small tooth so it was pretty hard to get good and clear photos. I’ll try to add some better ones later today. I have two confirmed Nano teeth I used as a comparison, they both look more slender than this one, but I’m not sure.

Hi I’ve been looking for a juvenile T Rex tooth and I came across this one, I was wondering if I can have some help to see if this is real? Thanks -Daniel

Microfossils are the means by which we can most fully appreciate the diversity of a past ecosystem. From salamanders to Tyrannosaurus, an ancient river captured and preserved dozens of species that lived in Montana 66 million years ago, at the terminus of the time of dinosaurs. In this small collection alone, I count at least 27 species of dinosaur, lizard, crocodile, fish, shark, salamander, turtle, mammal, and mollusk.-

Are Tyrannosaur fragments from hell creek really available for sale ? Any details on how they are labeled 'Tyrannosaur' would be helpful.

From the album: Hell Creek / Lance Formations
This kind of incisor-like ("incisorform") tooth was originally thought to have belonged to a large, Cretaceous mammal. Later discoveries revealed that these teeth were actually the front teeth ("premaxillary teeth") of Tyrannosaurs - and are now known as a hallmark of their clade, Tyrannosauroidea. Closely-spaced, parallel grooves on bones suggest that Tyrannosaurs used these teeth to scrape meat from bone. Given the size, this is from a very young animal. Should Nanotyrannus be valid, then this should be considered an indeterminate Tyrannosaurid. -
