3" Ceratopsian Frill Shield Section - Alberta (Disposition #000024-25)

Ceratopsian Frill Shield Section - Alberta (Disposition #-) #94868

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 (#000024-25) 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 section of frill shield from an unidentified species of Ceratopsian dinosaur. This comes from the late cretaceous Horseshoe Canyon Formation of Alberta. There are more than half a dozen species of Ceratopsians found in this formation including (Anchiceratops, Pachyrhinosaurus, etc) so it would be impossible to identify an isolated bone such as this down to the species or even genus level.

Ceratopsians are a group of plant-eating dinosaurs from the Cretaceous characterized by a bony frill on the back of the skull and a unique upper beak bone, called a rostral. Ceratopsians ranged in size from 1 meter (3 ft) and 23 kilograms (50 lb) to over 9 meters (30 ft) and 9,100 kg (20,100 lb). Triceratops is by far the best-known ceratopsian to the general public.
