Distribution and description of skull remains of the Pliocene antelope Sphenophalos from the northern Great Basin Province

Abstract

With the progress of paleontological explorations in the later Tertiary deposits of the northern Great Basin Province by the California Institute of Technology in cooperation with Carnegie Institution of Washington additional materials of the antilocaprid genus Sphenophalos have been found. Of particular interest is the discovery of remains of this mammal in new Pliocene faunas of eastern Oregon, thus extending the known range of Sphenophalos. While no complete skull is available, the specimens collected include a number of horn-cores whose structure is of considerable significance in a determination of the genetic relationships of the genus.

In the comparative studies of the Sphenophalos remains, frequent reference has been made to the original specimens collected in the Thousand Creek beds of northwestern Nevada. The loan of this material has been kindly permitted by Professor W. D. Matthew of the University of California. Dr. Joseph Grinnell of the Museum of Vertebrate Zoology has likewise permitted the loan of skulls of the modern pronghorn for examination. The special study of the occurrence and relationships of Sphenophalos was supported by funds from Carnegie Institution of Washington, generously granted by Dr. J. C. Merriam.
