Séquence des éruptions dentaires chez les Hyaenidae modernes et fossiles (Crocuta, Parahyaena, Hyaena)

Résumé

Few studies concern teeth eruption in hyenids. From observations on non-adult mandibles belonging to three extant species (spotted hyena, Crocuta crocuta; striped hyena, Hyaena hyaena; brown hyena, Parahyaena brunnea), tooth eruption sequences are recorded for young, juvenile and subadult individuals (i.e. from specimens younger than 15 months old). Tooth eruption sequences, crown wear and mandibular growth are presented and sometimes measured. These data fill previous published studies and are used on particularly well-preserved cave hyena (Crocuta intermedia) mandibles from the Lunel-Viel cave, dated to the Middle Pleistocene (~MIS 7). No major differences were found in the chronology of teeth eruption among hyenid species. Six age classes are presented for non-adult hyenids, based on tooth eruption, tooth wear and mandibular measurements. This ontogenetic classification could be an interesting step in assessing the function of Pleistocene sites (communal dens, birth dens)
