Also, the Chapala specimens share with Postcopemys a paraloph not aligned with the anterior arm of the hypocone in upper molars, but with the entolophid aligned with the anterior arm of the protoconid in lower molars, and the protolophule is absent in M1.
In the single M1 from La Bullana 2B, the metacone is placed in a more anterior position with respect to the hypocone than in D.
Rodriguez (9) states that past indigenous peoples are characterized by presenting high frequencies of winging, crowding, reduced hypocone, layered fold and P point of the protostylid, which places them closer to the Paleo-Indian sinodontes of the Mongoloid Dental Complex.
Considering the significant frequencies of Carabelli's cusp, cusp patterns X5 and X6 (36 and 46) and +4 and +5 (37 y 47), the relative frequency of cusp 7, the low frequencies of shovel-shaped incisors and double shovel, and the absence of hypocone reduction, one may conclude that the studied sample has a dental morphology typical of populations that make part of the Caucasoid dental complex.
4], small hypocone in the upper molars, and especially for its particular lower incisors, with a large, buccolingually enlarged crown and a thick root.
The median valley is filled with matrix and separates the protocone and hypocone.
schlosseri from Autol 1 and Moncalvillo, but the morphology of the anterior part of the mesoloph is quite different from these populations, where the mesoloph is always connected to the hypocone (Alvarez-Sierra, 1988).
Anteriorly the metacone is connected with the paracone and posteriorly it does not link with the hypocone.
In the genus Helladotherium, molars are provided with an enamel island in the hypocone (Gaudry, 1861).
hypocone extending back to the posterior border of the molar crown in Sivalhippus theobaldi; hypocone united to the posterior crescent in DP2 in Sivalhippus theobaldi; enamel borders of fossettes relatively simple in Sivalhippus theobaldi and complicated in Hipparion sp.
