The Cumberland Cave fauna exceeds that of other caves in number 

 of mammaUan genera recorded but includes a slightly smaller number 

 of species than recognized in either the Port Kennedy or Conard 

 Fissure occurrence. Of the 41 genera listed from Cumberland Cave 8 

 are extinct, and of 46 species about 28 are believed to represent extinct 

 forms. Thirteen of the 39 genera and about 37 of the 51 species in the 

 Port Kenned}^ fauna as listed are extinct. This suggests a somewhat 

 greater antiquity for the Pennsylvania assemblage. Thirty-eight 

 genera are recorded from the Conard Fissure, and of this number 4 

 are extinct, and about 19 of the 50 species are extinct. The Conard 

 Fissure fauna may be appreciably younger than either of the other 

 two, although O. P. Hay (1923, p. 14) believed that the Arkansas 

 occurrence antedated Cumberland Cave. Saber-toothed cats were 

 found in both Port Kennedy and Conard Fissm-e deposits and not in 

 Cumberland Cave, but tapir, mastodon, and Ardodus included in the 

 Cumberland Cave and Port Kennedy occurrences are absent from 

 Conard Fissure. It seems odd that sloth remains were not found in 

 either Conard Fissure or Cumberland Cave. Megalonichid material 

 is frequently encountered in caves, and species of this group of sloths 

 probably lived until near the close of Pleistocene time. 



If the Port Kennedy occurrence is considered as early Pleistocene, 

 that of Cumberland Cave may well be near middle Pleistocene in 

 age. However, the particular stage or stages represented remains 

 undetermined.
