Alberta [SEP] Paleontology
Alberta has one of the greatest diversities and abundances of Late Cretaceous dinosaur fossils in the world. Taxa are represented by complete fossil skeletons, isolated material, microvertebrate remains, and even mass graves. At least 38 dinosaur type specimens were collected in the province. The Foremost Formation, Oldman Formation and Dinosaur Park Formations collectively comprise the Judith River Group and are the most thoroughly studied dinosaur-bearing strata in Alberta. Dinosaur-bearing strata are distributed widely throughout Alberta. The Dinosaur Provincial Park area contains outcrops of the Dinosaur Park Formation and Oldman Formation. In the central and southern regions of Alberta are intermittent Scollard Formation outcrops.
