Revision de los mamíferos bunodontos de tipo nutria del Mio-Plioceno del Subcontinente Indio

摘要: A revision of the Enhydriodontini Indian Subcontinent is undertaken on basis previously described and recently collected bunodont otter-like fossils from sub-Himalayan Siwalik Group. It confirmed that, with passage geological time spanning period 13 – 3 Ma, there occurred a progressive increase in body size, reduction anterior part premolar row an degree cheek tooth bunodonty cusp mastoidization. Functional analysis snout partly preserved incisor battery Enhydriodon sivalensis , reveals that it was probably molluscivore, preying principally bivalves, while other species enhydriodonts were more likely to have been piscivores cancrivores.
