4.6" Hadrosaur (Edmontosaurus) Phalanx w/ Metal Stand - Wyoming

This is a 4.6" long phalanx (toe) bone of a hadrosaur (Edmontosaurus annectens), collected from our partner's lease on the Lance (Creek) Formation in Wyoming. It sits nicely on the accompanied metal display stand.

There are repaired cracks through this bone, some of which required gap fill restoration. Most of the restoration can be found on the proximal point of articulation.

Hadrosaurs are frequently referred to as duck-billed dinosaurs and are members of the Ornithischian family Hadrosauridae. They were fairly common herbivores that roamed Asia, Europe, and North America during the Upper Cretaceous Period. Many species of Hadrosaurs had distinctive crests on their heads, some of which had air-filled chambers that may have produced a distinct sound. These crests may have been used for both audio and visual display purposes.

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.
