>>6231168Therapsids in general had varying degrees of resembling modern carnivorans superficially, even the lines that didn't make it past the triassic. Saber teeth have evolved multiple times in therapsid evolution as a whole even in herbivores like Uintotheres. I honestly think not enough interest goes into ancient mammals considering how much they radiated after the Cretaceous in to a plethora of different forms. Permian life was not as exciting as Dinosaurs' but we did see the cousins of cynadonts evolve pretty similar features that gives them a more familiar look rather than dragons with upright legs.
