The Pleistocene Fossils of Porcupine Cave, Colorado

Show Summary Details


Porcupine Cave is the richest source of information on Irvingtonian-age vertebrates. Hundreds of thousands of vertebrate fossils have been recovered from Porcupine Cave, with thousands of identifiable specimens from the Pit and Velvet Room localities. This chapter documents the spatial distribution of the many different fossil localities and provides an overview of their suspected geological ages and general taphonomic settings. Most of the material described in this book was recovered from seven localities: the Badger Room, Fissure Fill A, the Gypsum Room, the Pit, and three spatially distinct excavations in the Velvet Room (Mark's Sink, DMNH 644, and CM 1927/UCMP V93175). Of these, the Pit locality provides the main basis for interpreting the effects of middle Pleistocene environmental change on ecology and evolution.
