... ) because there are hypsodont browsers today (e.g., goats, pronghorn, and camels [ O'Gara 1978 ; Kohler-Rollefson 1991 ]) as well as mesodont grazers (e.g., Indian chital and chousingha [ Schaller 1967 ]). Solounias and Semprebon (2002) report grazing in certain brachydont fossil equids. Table 1...

... information. Three classes of molar tooth crown height are recorded in the NOW database: brachydont, mesodont, and hypsodont. The criterion for assigning species to classes is based on the ratio of height to length of the second molar (upper or lower). Brachydont teeth have a ratio <0.8, mesodont teeth...

Strata observed by the writer to contain the marine pelecypod Brachydontes multilinigera has in this paper been included in the overlying Kaskapau formation. In the Pouce Coupe area this species occurs...

... Archaeopithecus rogeri , including also the monotypic genus Pachypithecus and its species P . macrognathus Ameghino, 1897 . According to Ameghino, Archaeopithecidae shared some features with primates, such as brachydont dentition and a primate-like jaw, which he cited as a reason to consider this family...

... by a central transverse valley, typical of heteormyids. No definite measurements can be made of either length or width due to the fragmentary nature of the specimen. Discussion .—This specimen is clearly a heteromyid with brachydont cheek teeth similar to Perognathus; however, due to its condition...

... and Brachydontes to shallow marine forms such as Inoceramus. The general fossil assemblages and configuration of the type Dunvegan Formation would suggest he marine margin of a delta. The stratigraphic relations of tlie formation are shown in Fig. 1. The Dunvegan Formation is generally accepted to be of an early...

... taxa (see Selig et al., 2019b ), as having an ectoloph requires that lower molars be characterized by tall cusps to allow for proper occlusion during mastication. Therefore, the relatively brachydont lower molars of Ptilocercus may relate to their brachydont upper molars that lack ectolophs. However...

... processes of some artiodactyl jaws. The teeth are brachydont, like those in palaeomerycids ( Figs. 2–4 ), and moderately worn. The crests and cristids are well developed, clearly marked, and not so worn as to be merged together. There are no cusps left as would be seen in unworn teeth, even in the M 3...
