The Dinosaur Park Formation is the uppermost member of the Judith River Group, a major geologic unit in southern Alberta. It was laid down over a period of time between about 76.5 and 75 million years ago. The formation is made up of deposits of a high-sinuosity (anastomosing) fluvial system, and is capped by the Lethbridge Coal Beds. The formation is bounded by the Oldman Formation below it and the marine Bearpaw Formation above it (Eberth, 2005).
It is known for the dense concentrations of dinosaur skeletons, both articulated and disarticulated, that are found there. However, other animals such as fish, turtles, and crocodilians are also abundant in the formation. The formation has been named after Dinosaur Provincial Park, a UNESCO World Heritage Site.

“Out of my discomforts, which were small enough, grew one thing for which I have all my life been grateful—the formation of fixed habits of work.”
