The fresh unusual form of the p4, without mesolingual conid, are characteristic of Tragulidae and you can Bachitheriidae , , . The combination from an effective tusk like p1, a highly elongated diastema anywhere between p1 and you can p2 which framework of one’s p4 is exclusive among ruminants and suggest the new Bachitheriidae , . This new distinction anywhere between Bachitherium varieties is usually predicated on proportions variations , . However the diastema length , the newest size of this new postcranial remains , , and you can differences in the entire shape of new mandible , , , correspond to a kinds-particular ecomorphology. The newest p3 and you will p4 from Bachitherium specimens of Gaimersheim1 is keeps neocrista inside straight back area. Blondel contends that this element is unique among the Bachitheriidae and you may try an enthusiastic autapomorphy of your kinds B. lavocati. However, similar features have now been seen towards B. curtum and you will B. insigne, although they stays unusual . Aiglstorfer et al. have already shown the enormous variability as new traguline p4 in one species. This new p4 of Tragulidae Dorcatherium naui is also lack the cristid creating new lingual edge of the brand new enamel on entire mediator you’ll . The dimensions of tooth studied here is nearly the same as the ones from Bachitherium curtum and you may B. lavocati , , , (select S1 Annex). not, the fresh new diastema period of the new specimens out of Gaimersheim try more than those of the small B. curtum, just what certainly corresponds to the fresh prognosis regarding B. lavocati advised from the Sudre . Until now, Bachitherium lavocati was only known from the Pech Desse area , .

Looking at the illustration of Martinez Sudre and you may Sudre , B. curtum, B. viretti, and you can B. guiroutensis have trochleas faster lined up than simply into the B. lavocati. Also, the latest lips of your proximal trochlea, within the B. guiroutensis commonly symmetrical, in comparison to B. lavocati. Provided all these have, our very own specimen are most like Bachitherium lavocati.
