The Fossil Horses of the Texas Gulf Coastal Plain: A Revision
MetadataShow full item record
Sixteen species of nine genera of fossil horses from the Texas Gulf Coastal Plain are redescribed or described and compared with forms known from other areas of North America. Similar forms are found to occur especially in faunas of the Great Plains, Florida, and the West Coast. The evolution of the coastal plain horses and their presumed phylogenetic importance is discussed. The fossil horses are shown generally to confirm Patton's (1969) correlation of the four local faunas of the Texas Gulf Coastal Plain.
