Show Summary Details


This chapter presents a summary of fossilized species lists for each locality in Porcupine Cave, and provides estimates of number of identifiable specimens (NISP) and minimum numbers of individuals (MNI) for each species at each locality. These lists make clear that the most abundant fossils are those of small mammals, particularly rodents such as ground squirrels, wood rats, and voles, which are represented by thousands of specimens each. Other rodents and rabbits are commonly represented by hundreds of specimens per species. Insectivores, carnivores, and ungulates are much less common and typically are known by tens of specimens. Each amphibian, reptile, and bird species generally is represented by fewer than 10 specimens.
