Hadrosaur Toe Bone (Ungual), Alberta (disposition #001590)

A partial hadrosaur ungual, or terminal toe bone, from Alberta. This element occupied the end of a toe and supported its hoof-like keratin covering. This specimen is rounded from water erosion. This likely occurred after the animal's remains were scattered and entered a stream or river system prior to burial in sediments. Unguals are surprisingly hard to find and complete ones are rare; probably due to their porous (somewhat delicate) nature. For one to survive a journey down an ancient river and several million years of burial is quite fun to think about!

Hadrosaurs, commonly known as duck-billed dinosaurs, had broad terminal toe bones suited to supporting their weight. In life, the preserved bone would have formed the core of the toe’s hoof-like tip; the original keratin covering is not preserved.

From the Harvey Negrich Collection, this compact specimen combines recognizable anatomy with collection provenance. Its juvenile size makes it an interesting companion to larger dinosaur foot bones in a comparative or educational display.
