Composite Hadrosaur Finger - Alberta (Disposition #000028-29)

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. Currently only a few fossil types are eligible for disposition. These include 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 nicely preserved set of Hadrosaur finger bones from the Horseshoe Canyon Formation in Alberta, Canada. The bones are articulated, however the finger is a composite, consisting of bones from separate Hadrosaurs. They come from an unidentified species of hadrosaur and are Upper Cretaceous in age, between 74-67 million years old. It comes with a large floating display case.

The distal phalanx (ungual) is 2" long, the medial phalanx is 1.3" long and the proximal phalanx is 1.9" long.

There are multiple species of Hadrosaur that come out of the Horseshoe Canyon Formation. The Hadrosaurs that have been identified are Edmontosaurus, Hypacrosaurus, Parksosaurusa and Saurolophus. Due to the bone similarities of these dinosaurs, bones of the feet especially, as well as the unrecorded specifics from the original collector, I cannot provide an accurate genus/species identification.

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