Also known as OMNH V682

Where: Roger Mills County, Oklahoma (35.6° N, 99.8° W: paleocoordinates 35.9° N, 98.2° W)

• coordinate estimated from map

When: Ogallala Formation, Clarendonian to Clarendonian (12.5 - 2.6 Ma)

• "It is in an area in which the Permian red beds under- lying the Ogallala Formation are tilted and jumbled as a result of collapse due to salt dissolution. The overlying Ogallala beds are horizontal and not well exposed due to covering vegetation. "

•

•"Many of the localities yielding vertebrate fossils in west-central Oklahoma occur along the outcrop margin of the Ogallala Formation, where there seems to be extensive reworking of the Ogallala sediments. This and the paucity of age-diagnostic taxa make it difficult to assign most of the Roger Mills County localities to a land mammal age."
