English: Spermophilus richardsonii (Sabine, 1822) - fossil ground squirrel skeleton from the Pleistocene of Nebraska, USA. (Nebraska State Museum of Natural History, Lincoln, Nebraska, USA)
This species is also known as Urocitellus richardsonii.
From museum signage:
"Ice Age ground squirrel which died in its burrow
Dundy County
10,500 years old (Pleistocene)
This is one of the youngest fossils in our collection. To be considered a fossil, a specimen must be at least 10,000 years old. Carbon-14 dates on this specimen barely exceed this. The skeleton is similar to that of living Richardson's ground squirrels living in the Rocky Mountains and northern Great Plains today.
