A tiny, cat-sized deer once roamed the prehistoric Great Plains. When it died, it became part of the rock bed at Badlands National Park.
Around 32 million years later, an intern discovered and properly reported the skull of this individual deer.
Researchers soon realized the skull was unique. Not only is it the first fossil discovered in a new species, it's the first of a new genus.
Mattison Shreero is a park ranger, geologist and paleontologist and one of the main researchers on the paper describing Santuccimeryx. She shares why this tiny deer has big implications for the scientific record.
