9.1" Hadrosaur Chevron Bone - Alberta (Disposition #000028-29)

Hadrosaur Chevron Bone - Alberta (Disposition #-) #129790

First, a note on the legality of this fossil. Alberta has very strict laws pertaining to fossil collection. Fossils may not be removed from the province of Alberta without permission from the government. To gain ownership of a fossil, you must be issued a Disposition Certificate from Alberta's Royal Tyrrell Museum. Only a few fossil types are currently eligible for disposition: mostly ammonites, petrified wood, leaves and fossil oysters.

This specimen is part of a collection of dinosaur material that was collected by a single individual (Steve Walchina) decades ago prior to the current law. Because it was collected before the law went into effect, the collection was "grandfathered" in. The collection was reviewed by the Royal Tyrrell Museum and a disposition certificate issued for portions of it that were not considered scientifically significant. This moved the fossils into private ownership and allowed them to be removed from the province. The disposition certificate (#000028-29) is on file with the Royal Tyrrell Museum. This makes the small amount of Alberta dinosaur fossils we recently acquired from this collection some of the only legal Alberta dinosaur material on the market.

This is a beautifully preserved Hadrosaur chevron bone from the Horseshoe Canyon Formation of Alberta, Canada. It comes from an unidentified species of hadrosaur and are Upper Cretaceous in age, between 65-74 million years old. There are repaired cracks throughout the specimen, however restoration is quite minimal. The vast majority of the restoration is as gap fill between portions where the bone broke and crumbled. The distal end of the chevron is broken.

The Horseshoe Canyon Formation yields many different species of Hadrosaur, including Edmontosaurus, Hypacrosaurus, Parksosaurus and Saurolophus. Due to the similarities of these dinosaurs and the unrecorded specifics from the original collector, individual bones, especially of the feet and hands, do not have a guaranteed identification.
