Wehrli considered that the size change represents an intimate dimorphism

The latest peculiar form of the fresh new p4, as opposed to mesolingual conid, is actually feature of Tragulidae and you will Bachitheriidae , , . The blend out-of a good tusk for example p1, a very elongated diastema ranging from p1 and you may p2 hence framework of one’s p4 is unique one of ruminants and you will indicate the Bachitheriidae , . Brand new differentiation ranging from Bachitherium types is certainly caused by based on proportions distinctions , . Nevertheless the diastema length , brand new proportions of the latest postcranial remains , , and variations in all round model of the newest mandible , , , match a varieties-certain ecomorphology. The new p3 and p4 from Bachitherium specimens out of Gaimersheim1 can enjoys neocrista in the back area. Blondel argues that this element is special among Bachitheriidae and you will is a keen autapomorphy of the species B. lavocati. But not, similar provides are noticed to the B. curtum and you can B. insigne, in the event they stays rare . Aiglstorfer ainsi que al. have already revealed the large variability as brand new traguline p4 in one kinds. The fresh p4 of one’s Tragulidae Dorcatherium naui normally lack the cristid creating new lingual side of the tooth towards the whole mediator you’ll . How big is one’s teeth studied here is nearly the same as the ones from Bachitherium curtum and you can B. lavocati , , , (find S1 Annex). Yet not, new diastema period of brand new specimens from Gaimersheim is actually more than those of the small B. curtum, exactly what clearly represents the fresh new diagnosis out-of B. lavocati suggested by the Sudre . Up to now, Bachitherium lavocati was just recognized in the Pech Desse locality , .

Description discussion

The new sample MNHN LIM157 gifts an equivalent morphology to people from Bachitherium for the which have trochleas not lined up. New edges try somewhat additional in dimensions and highest, brand new outside that being larger. New plantar crest try missing. There clearly was a huge plantar projection of interior lib out-of the latest proximal trochlea. As a result of the size provided by Martinez Sudre , so it fossil was huge (dorso-plantar height: several.cuatro mm and size: 13.3) than simply specimens regarding B. viretti and you may B. curtum, and might correspond to very big B. lavocati or even the mean size of B. guiroutensis (B. insigne becoming maybe not discussed). Looking at the instance of Martinez Sudre and you may Sudre , B. curtum, B. viretti, and you can B. guiroutensis have trochleas quicker aligned than simply for the B. lavocati. Also, the newest mouth area of the proximal trochlea, inside B. guiroutensis commonly symmetric, in comparison to B. lavocati. Offered each one of these have, the specimen is very the same as Bachitherium lavocati.
