... of the deciduous and permanent dentition of Interatherium and Protypotherium (Interatheriinae) is presented, based mainly on unpublished materials. Deciduous cheek teeth are brachydont and placed covering the apex of the respective permanent tooth; in addition, some morphological and metrical differences...

... (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 shows summary conclusions from other...

... of the tooth enamel itself is smooth, and cusps and crests are rounded. The teeth are brachydont. Fig. 2. Photograph of Boreameryx braskerudi , holotype, left jaw fragment with m1–m3 (CMN 52710). (A) medial view; (B) occlusal view; (C) lateral view. The basic four-cusped selenodont structure...

... 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...

... , 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 in the Prosimiae, just...

.... Prosciurus ? Rensberger and Li , 1986 , p. 764, figs. 1–1, 1–3, 2. Pseudallomys Korth , 1992 , p. 171, fig. 1. Cheek teeth brachydont, unlike meniscomyines and aplodontines, but with high cusps and crests, accounting for roughly a third of the total tooth height, unlike prosciurines...

... pelecypod Brachydontes multilinigera has in this paper been included in the overlying Kaskapau formation. In the Pouce Coupe area this species occurs approximately 120 feet above the top of the formation whereas along the creeks north of Spirit River approximately 50 miles east, it occurs precisely...

...-fill, and brackish-water bivalves ( Brachydontes , Ostrea ) in the intervening mudstone. The channel cuts down through laminated and cross-bedded sandstone representing foreshore and surf zones, to rest on swaley cross-stratified sandstone representative of the middle shoreface. See Fig.  3...

... 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, no specific identification can be made. Perognathus ranges from the Hemingfordian to Recent throughout most...

...Figure 2. Cheek tooth crown height in extant and fossil equids. A, B, Basic tooth morphology, redrawn from Janis and Fortelius (1988) . A, Brachydont, or low-crowned (human) tooth. The crown is defined as the enamel-covered part of the tooth above the gum line ( Peyer 1968 ). B, Hypsodont...

... 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...

... specimen except for the anterior part of the M 1 , which is slightly broken (Plate II, 5; Table 2 ). The cheek teeth are brachydont, presenting a middle stage of wear. The basal cingulum is slightly seen in these teeth. The M 1 looks smaller in size than the M 2 . The entostyle is absent in the M 1...

... tooth row; plane of angular process inclined medioventrally making medial surface of mandible strongly concave, tooth row not vertically aligned with lower incisor; cheek teeth brachydont to mesodont and lophate; dental formula 1/1–0/0–1/1–3/3; P4–p4 progressively larger relative to M1/m1; distinct...

...–9,350 feet are definitely Mesozoic in age, but there is uncertainty as to the precise position of the sediments. Reeside 5 identified Ostrea, Alectryonia, Plicatula, Camptonectes? , and Brachydontes from the core at 9,115–9,116 feet. Henbest 6 reports that the foraminifer related...
