Younger Dryas Mammal Distribution

The stag-moose (Cervalces scotti) is an extinct deer slightly larger than the modern moose. Stag-moose went extinct sometime between 11,000 and 10,000 years ago.

The snowshoe hare (Lepus Americanus) is a medium-sized rabbit. Today, the snowshoe hare is found in northern and higher elevation areas of North America. However, the bones of this animal have been found in several midwestern paleontological sites. These finds indicate that the snowshoe hare's range included much of the midwestern U.S. during the last glaciation. The presence of animals like the snowshoe hare in the southern portion of the midwestern U.S. during the last glaciation provides evidence that the climate was cooler at that time. Particularly, it indicates that the summers were probably significantly cooler than the area experiences now.
