What is High occurrence of a basicranial feature in Homo erectus: Anatomical description of the preglenoid tubercle about?

## Abstract The degree of differentiation between Western and Eastern Early Middle Pleistocene hominids (__Homo erectus__) is still under debate. On the one hand, the two populations are believed by some to belong to two separate taxonomic categories possessing their own exclusive features. On the other hand, they are considered by others to belong to a single but ubiquitous global population with regional specificities that are mainly due to variations in the frequency of certain features. In this context, an additional trait, the preglenoid tubercle (__tuberculum anterius fossae mandibularis__), may well shed light on the matter. The tubercle is often present on the anterior part of the __fossa mandibularis__ at the anterior extent of the joint capsule and articular tubercle (__tuber articulare__) of fossils usually assigned to __Homo erectus__. This study describes the anatomy of the preglenoid tubercle, to indicate its occurrence and to try to improve its use in taxonomy and phylogeny, although its origin and functional significance have not yet been clarified.
