Wehrli thought that the scale differences corresponds to an intimate dimorphism

New peculiar model of the latest p4, as opposed to mesolingual conid, is actually characteristic of your own Tragulidae and you may Bachitheriidae , , . The blend regarding an effective tusk instance p1, an extremely elongated diastema anywhere between p1 and p2 and therefore construction of the p4 is special among ruminants and suggest brand new Bachitheriidae , . The fresh new distinction between Bachitherium varieties is mostly considering dimensions differences , . Nevertheless diastema duration , brand new size of new postcranial remains , , and you may variations in all round model of the newest mandible , , , correspond to a species-particular ecomorphology. New p3 and p4 out-of Bachitherium specimens regarding Gaimersheim1 can features neocrista from inside the right back valley. Blondel contends that ability is unique one of many Bachitheriidae and are an enthusiastic autapomorphy of varieties B. lavocati. However, comparable provides have now been observed for the B. curtum and you can B. insigne, in the event they remains unusual . Aiglstorfer mais aussi al. have already found the huge variability in the shape of the latest traguline p4 in one varieties. The p4 of one’s Tragulidae Dorcatherium naui is lack the cristid creating the new lingual side of the enamel towards the entire intermediary you’ll be able to . How big tooth analyzed the following is much like those of Bachitherium curtum and you can B. lavocati , , , (look for S1 Annex). However, the latest diastema duration of this new specimens away from Gaimersheim is actually longer than those of the tiny B. curtum, exactly what clearly represents the newest diagnosis out of B. lavocati recommended by Sudre . Up to now, Bachitherium lavocati was just understood from the Pech Desse locality , .

Description discussion

This new sample MNHN LIM157 presents an identical morphology to those regarding Bachitherium inside which have trochleas not lined up.
