.48" Fossil Dinosaur (Leptoceratops) Shed Tooth - Wyoming

This is a .48" long tooth from the elusive ceratopsian dinosaur, Leptoceratops gracilis. It was collected from our partner's private lease on the Lance (Creek) Formation in Wyoming.

Leptoceratops gracilis is the only Leptoceratopsid (previously protoceratopsid) found in North America. Like Triceratops, they shed teeth during their lifetime and collectors often refer to these teeth as "spitters". This "spitter" has a polished upper surface indicative of a lot of wear from grinding food.

Comes with an acrylic display case.

About Leptoceratops

Leptoceratops was a small, primitive genus of ceratopsian dinosaur whose name literally means "small-horn face" despite the fact it did not have any horns. It reached lengths of about two meters and appears to have had the characteristics of a bipedal dinosaur, likely being able to stand and run on its back legs. However, even though they weren't able to pronate their "hands", it's likely they could walk on all four legs. As with other ceratopsians it has a parrot-like beak and was probably able to chew very tough vegetation.

About The Lance Formation

The Lance Formation of eastern Wyoming is a Late Cretaceous (69–66 million years old) unit that represents the same geologic age as the famous Hell Creek Formation of Montana and the Dakotas. Although they are time-equivalent, the Lance and Hell Creek preserve subtly different environments. Hell Creek reflects a humid, forested coastal plain punctuated by volcanic ash deposits, while the Lance records a slightly drier, more open floodplain landscape with broader river systems and fewer ash layers. Together, they provide a complementary view of life in the final chapter of the dinosaur era.

Perhaps the most famous Lance resident would be Tyrannosaurus rex, the largest North American carnivore to ever live. However, other smaller theropods also roamed the American midwest in this subtropical coastal stream system, including the beaked Ornithomimus, a lanky running theropod with a build similar to a modern ostrich, as well as several small predatory troodonts such as Paronychodon and Pectinodon.

Herbivorous dinosaurs also took advantage of the abundance offered by this unique era. Armored ankylosaurs dwelt in herds, their safety assured by their numbers, their heavy bone plating protecting most of their bodies and even their eyelids, and huge bone clubs on the ends of their tails providing them with powerful offensive capabilities. Ceratopsians like the famous Triceratops also formed protective herds, guarding their necks with frills and horns. Their smaller relatives, the dome-headed pachycephalosaurs, were also well represented in the area. Hadrosaurs, duck-billed titans with huge batteries of plant-grinding teeth in elongated snouts, are also well known from the region.

In addition to dinosaurs, a wide variety of fishes, amphibians, lizards, snakes, turtles, champsosaurs, crocodilians, and pterosaurs have been found in the formation.
