InGen Database Description
The Scollard Formation is part of the Western Canada Sedimentary Basin in south-western Alberta. The formation's name is derived from the Scollard Canyon in Buffalo Jump Provincial Park. It lies beneath the Paskapoo Formation (until more recently considered as the uppermost member of the Edmonton Group) and above Battle Formation. It dates to the Maastrichtian age of the Late Cretaceous period, and Danian age of the Paleogene, 70 and 66 million years ago.
Deposits from the time of the Cretaceous-Paleogene (K-Pg) extinction event can be found here, meaning that the lower member records the end of the dinosaurs, and the upper member the dawn of mammals.
This formation consists of sandstone, shale, and siltstones. Mudstones and coal seams are also present, as well as bentonite clays.
The site has revealed several dinosaur species, a few mammal specimens, and plant fossils including ferns and conifers.
- Neither Chasmosaurus nor Corythosaurus fossils are found in the Scollard Formation's real-life counterpart.
- Tyrannosaurus, Triceratops, and Edmontosaurus are all found in the Scollard Formation's real-life counterpart.
