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]
