Middle Pleistocene (Irvingtonian) Ochotona (Lagomorpha: Ochotonidae) from Porcupine Cave

Show Summary Details

Preview

The lagomorph family Ochotonidae, represented today by a single living genus (Ochotona [pika]), originated in the middle Oligocene of Asia. The North American record of Ochotona is sparse until the early Pleistocene Irvingtonian, when a more widespread occurrence is indicated. At least two morphological forms of Ochotona lived in North America during the Irvingtonian, one large and one small. This chapter presents the first record of Irvingtonian Ochotona from the intermountain West, a record from high-elevation Porcupine Cave, Colorado.
