Asiatheriidae
Asiatheriidae ("Asian opossums") is an family of Cretaceous metatherians in the order Asiadelphia. Different from the Ameridelphia, they lacked a prominent distolateral process on the scaphoid, and possessed a more slender fibula. The masseteric fossa is deeper in this group than the true marsupials.

gollark: What do you mean you "perceive" time as discrete? You mean you *arbitrarily think so*, or what?
gollark: Quite a lot.
gollark: > The Planck time is the unique combination of the gravitational constant G, the special-relativistic constant c, and the quantum constant ħ, to produce a constant with dimension of time. Because the Planck time comes from dimensional analysis, which ignores constant factors, there is no reason to believe that exactly one unit of Planck time has any special physical significance. Rather, the Planck time represents a rough time scale at which quantum gravitational effects are likely to become important. This essentially means that while smaller units of time can exist, they are so small their effect on our existence is negligible. The nature of those effects, and the exact time scale at which they would occur, would need to be derived from an actual theory of quantum gravity.
gollark: Oh, no, never mind, that's not it.
gollark: ... you mean the Planck time or something?
