If no rank is listed, the taxon is considered an unranked clade in modern classifications. Ranks may be repeated or presented in the wrong order because authors working on different parts of the classification may disagree about how to rank taxa.
|C. B. Schultz and C. H. Falkenbach 1941||SKULL.-Smaller than that of U. major and larger than that of U. medius; fan-shaped occipital region not as wide as in U. major; brain case slightly more inflated than in U. major; nasals shorter than in U. medius and decidedly longer than in U. major, and with less retraction than in the latter species; anterior tip of nasals retracted to region above P 2 ; paroccipital process long and tapered; postglenoid process not as heavy as in U. major.
MANDIBLE.-Typical of the genus, intermediate in size between those of U. medius and U. major.
DENTITION.-Superior and inferior series intermediate in length between those of U. medius and U. major.
LIMBs.-Shorter and lighter than in U. major; longer and heavier than in U. medius.
