Paleo Poop™ is a rare piece of coprolite (ˈkä-prə-ˌlīt) from Canada, a.k.a. fossilized dung, estimated to be over 66 million years old.

Most coprolite has been washed away and disintegrated over the years. However, there are some areas that contained clay and were situated in just the right climate conditions that allowed them to be preserved.

One of these areas happened to be near Assiniboia, Saskatchewan. Dinosaurs were attracted to this area, which had been the flood plain of a large, meandering stream. The fine sediment from the flood plain protected the coprolite, where it fossilized and became a piece of history.
