Ochotona spanglei is an extinct species of pika (mammal in the family Ochotonidae), known from Late Miocene - Early Pliocene fossil from Oregon (USA).[1][2][n 1] Fossils were also found in Nebraska referred to as Ochotona cf. spanglei.[2][3][n 1]
Ochotona spanglei is the earliest known pika, which inhabited North America. Pika came at the Miocene-Pliocene boundary from Eurasia. Extinction of O. spanglei was followed by an approximately three-million-year-long gap in the known North American pikas record.[4]
Fossil distribution
- McKay Reservoir, Oregon, McKay Formation, Hemphillian (10.3 - 4.9 Ma), Ochotona spanglei, the species was discovered here[2][n 2] (described from a lower jaw with complete cheek dentition)[1]
- Honey Creek, Nebraska, Hemphillian (10.3 - 4.9 Ma), Ochotona cf. spanglei[2][3][n 3]
- Mailbox Prospect, Antelope County, Nebraska, Late/Upper Hemphillian (10.3 - 4.9 Ma), Ochotona cf. spanglei[2][3][n 4]
