Menoceras barbouri

Mammalia - Perissodactyla - Rhinocerotidae

Taxonomy
Diceratherium barbouri was named by Wood (1964) [type incorrectly said to be MCZ 7445 by Prothero and Sereno 1987]. Its type specimen is M.C.Z. No. 4452, a partial skull (palate, basis cranii and occiput), and it is a 3D body fossil. Its type locality is Thomas Farm, which is in a Hemingfordian terrestrial sandstone/claystone in the Alachua Formation of Florida.

It was recombined as Diceratherium (Menoceras) barbouri by Wood (1964); it was recombined as Menoceras barbouri by Prothero and Manning (1987), Prothero (2005).

Diagnosis
ReferenceDiagnosis
M. S. Stevens et al. 1969 (Moschoedestes delahoensis)A rhinoceros of larger size, and much higher crowned cheek teeth than Menoceras cooki.
L. G. Tanner 1972 (Menoceras falkenbachi)Male skull U.N.S.M. 1241 larger than Menoceras arikarense (Barbour); see Tables 1-3 and Figs. 1-2. Smaller in nearly all dimensions than Menoceras marslandensis. The frontal rugosities and convexity of the holotypic skull are relatively less prominent than that of the holotype of M. marslandensis. The bosses at the tips are more roughened anteriorly than those of Menoceras arikarense, but relatively less than Menoceras mars/andensis. The skull U.N.S.M. 62006 (Tanner, 1969, p. 402) demon- strates the male characteristics of the species as does the holotypic skull, U.N.S.M. 1241 (Fig. 1-2). The female skull, U.N.S.M. 1238, has several dimensions nearly equal to those of the type male skull, U.N.S.M. 1241, the main exception being the relative dimensions of the nasals (see Table 1).
