FIG. 3 in Extending the tooth mesowear method to extinct and extant equids
FIG. 3. — Geographic situation of the Vallesian (MN9) fossil localities of the Dinotheriensande (black signatures). The localities of Eppelsheim (Ep), Esselborn (Es) and Westhofen (We) are highlighted (after Franzen 1997 and Kaiser et al. in press).
FIG. 2 in Extending the tooth mesowear method to extinct and extant equids
FIG. 2. — Longitudinal section of the scull of a six year old individual of Equus ferus Boddaert, 1785 (after Butz & Böttger 1946). The tooth alveolae are opened. Note the differences in tilt of the individual cheek tooth positions as indicated by lines. In the upper premolars P2 and P3 the angle between the occlusal surface and the anterior wall of the tooth is open, in the upper P4 and M1 it is about rectangular, and in the upper molars M2 and M3 the occlusal surface forms a close angle with the anterior wall (bold lines). P2 and P3, as well as M2 and M3 are therefore easily to be identified if isolated. P4 and M1 however are to be distinguished with a great degree of uncertainty. The same applies to the lower premolars and molars. Scale bar: 5 cm.

A new faunistic component of the Lower Triassic Panchet Formation of India increases the continental non-archosauromorph neodiapsid record in the aftermath of the end-Permian mass extinction
<p>The fossil record of Early Triassic diapsids is very important to understand how the end-Permian mass extinction affected ecosystems and the patterns and processes involved in the subsequent biotic recovery. Vertebrate fossil assemblages of continental deposits in current-day South Africa, China and Russia are the best source of information of this clade during the aftermath of the extinction event. Although considerably less sampled, the Induan continental rocks of the Panchet Formation of the Damodar Basin (eastern India) have also yielded a relatively diverse vertebrate assemblage composed of fishes, temnospondyls, synapsids, and a single proterosuchid taxon. Here, we report on a small isolated diapsid partial ilium (ISIR 1132) from the upper Panchet Formation. This specimen has a distinct morphology to that present in other tetrapods that we are aware of, including a shallow emargination on the dorsal margin of the anterior portion of the iliac blade, and ratio between height of iliac blade versus maximum height of iliac acetabulum at level of the dorsalmost extension of supraacetabular crest ≤0.45. Comparisons and a quantitative phylogenetic analysis found ISIR 1132 as a non-archosauromorph neodiapsid. This new specimen expands the reptile diversity in the Panchet Formation as well as for the rest of Gondwana, where Early Triassic non-archosauromorph neodiapsid species are extremely scarce.</p>
