American species (P. citofluminis Storer, 1984, and P. lateriviae Storer, 1988), and the Asian species P. mongolicus Kowalski, 1974. The other three species previously assigned to Pseudocylindrodon are here referred to the new genus Dolocylindrodon: D. medius (Burke, 1938), D. tobeyi (Black, 1970), and D. texanus (Wood, 1974) based on a combination of cranial and dental morphology. Two new species of Dolocylindrodon are named from the Chadronian part of the Climbing. Arrow Formation of southwestern Montana: Dolocylindrodon vukae (type species of the genus) and Dolocylindrodon rahnensis. Additional specimens of D. medius from the early Chadronian McCarty's Mountain fauna of Montana are briefly discussed. The recognition of a new genus and two new species of cylindrodonts increases the known diversity of this famil... |
