Indodelphisis an extinctgenusofopossum-likemetatherianfromEoceneofCambay Shale FormationofIndia.Thetypeand the onlyspeciesisIndodelphis luoi.[1]
Indodelphisis the only known metatherian fromInsular India(another,Jaegeria,has had its metatherian status questioned). It is known from the well-preserved lower molars of two individuals. This species probably represents the oldest known record ofCenozoicmetatherians fromAsia,and it occurs in association with a diverse landmammalfaunacomprisingperissodactyls,artiodactyls,insectivores,laurasiatherians,apatotherians,bats,rodents,and several other taxa currently under study.[1]
It was initially assigned to thePeradectidae[1],but more likely belongs to theHerpetotheriidae.It may possibly be a junior synonym ofAsiadidelphisfrom the Paleogene of Pakistan and Kazakhstan, which is known only from upper molars.[2]It is unknown whetherIndodelphisdescended from a metatherian that colonized Insular India from Asia, or if it was a relict of India's originalGondwananmammalian fauna.[3]
