       Though commonly stated to be mammal,‭ ‬the evolutionary placement of Yanoconodon‭ ‬amongst mammals is uncertain due to the fact that Yanoconodon shows a development of an inner ear.‭ ‬This is an‭ ‬advanced feature upon what otherwise might be interpreted as a more primitive mammaliaform body.
