Thylcinids have canine teeth - indicative of a carnivorous ancestry.
The thylacoleonids and the carnivorous macropods do not possess canine
teeth - the big, sharp, pointy things at the front which look and work like
canines, are actually insisors.

Many say it was a mistake to come down from the trees, some say
the move out of the oceans was a bad idea. Me, I say the stiffening
of the notochord in the Cambrian was where it all went wrong,
it was all downhill from there.
