Abstract
The study of hipparion deciduous cheek teeth from the Dorn-Dürkheim 1 locality reveals a morphology of these specimens that differs from adult material in featuring less developed occlusal enamel features. Dorn-Dürkheim 1 deciduous cheek teeth are comparable in size to specimens from the early late Miocene (MN9, early Vallesian) Höwenegg and Eppelsheim localities. Size differences are too small to justify the recognition of more than one species of hipparion at Dorn-Dürkheim 1 based on deciduous material alone. Comparison with deciduous teeth from North American Cormohipparion and hipparionines from various Old World localities shows commonalities among all studied deciduous cheek teeth, such as frequently open pre- and postflexids in mandibular specimens. Size differences between maxillary dP3s and dP4s are negligible, while mandibular dp3s are often wider than dp4s. Ectostylids are common in mandibular deciduous cheek teeth of North American hipparions and, in the Old World, among the members of the “Sivalhippus” Complex, for example. However, they become less frequent in more advanced members of the Hippotherium lineage, as is already apparent in the hipparionines from Dorn-Dürkheim 1. This variation underlines the significance of deciduous cheek teeth for future phylogenetic studies.
