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.

“The label of liberalism is hardly a sentence to public igominy: otherwise Bruce Springsteen would still be rehabilitating used Cadillacs in Asbury Park and Jane Fonda, for all we know, would be just another overweight housewife.”
—Barbara Ehrenreich (b. 1941)
“Those who were skillful in Anatomy among the Ancients, concluded from the outward and inward Make of an Human Body, that it was the Work of a Being transcendently Wise and Powerful. As the World grew more enlightened in this Art, their Discoveries gave them fresh Opportunities of admiring the Conduct of Providence in the Formation of an Human Body.”
—Joseph Addison (1672–1719)
