Nanotyrannus Teeth (Little T-Rex)

Nanotyrannus Teeth from the Hell Creek Formation for Sale

Buried Treasure Fossils offers Nannotyrannus teeth for sale. Nanotyrannus or "tiny tyrant" is the smaller tyrannosaurid dinosaur from the late Cretaceous period believed to reach 20+ feet. In October 2025, new research was presented by Lindsay Zanno and James Napoli from the North Carolina Museum of Natural Sciences with their recently acquired “Dueling Dinosaurs” Tyrannosaur skeleton has changed the Nano versus T. rex species discussion. Their paper presented at the 2025 Society of Vertebrate Paleontology meeting concluded that Nanotyrannus is a real, unique species and not a juvenile T. rex. This catalog contains Nanotyrannus teeth, dinosaur bones, and dinosaur claws, and are highly valued by collectors. These top quality specimens were all legally collected from private lands in the northwestern US. Late Cretaceous, Hell Creek Fm. (or equivalent), 68-66 MYA. Authenticity guaranteed.

What the Listing Details Actually Tell You

Tooth position reveals a lot about Nanotyrannus teeth. Maxillary teeth are broad and blade-like, while dentary teeth are narrower. Smaller anterior dentary teeth are ideal for gem jar displays.

Condition descriptions are important as well.

Details such as enamel quality, serrations, intact tips, and any repairs can help you understand the condition of a specimen. Crack fill on rooted specimens is disclosed separately from restoration.

Buried Treasure Fossils provides the formation, the county, and the tooth position on every listing, along with any crack, repair, or restoration. If you are researching what makes fossils genuine, these details can help you evaluate a specimen more carefully. A listing that specifies Hell Creek Formation and Powder River County provides more specific provenance information than one with only a general location.

FAQs

What is the difference between a shed tooth and a rooted tooth? Tyrannosaurids replaced teeth throughout their lives, and a shed tooth crown separates from the root in the jaw. Rooted teeth retain part of the root, which can make them less common than shed crowns and potentially more valuable to collectors.

Why do some teeth sit on a piece of rock? Those are matrix specimens, left in the sediment they were recovered from rather than removed from it. The matrix confirms the horizon the tooth came from and appeals to collectors who want the geology included in the display.

How does a Nanotyrannus tooth differ from a juvenile T. rex tooth? Nano teeth are more laterally compressed and blade-like in cross section, while T. rex teeth are thicker and rounder. Serration density differs as well, though locality and position data on the listing matter as much as the anatomy.

Does a conchoidal fracture reduce value? Not always. Where the fracture happened before burial, it is part of the specimen's history rather than collection damage, and listings here note which is which.
