When did the first carnivorous mammals appear?
Quick Answer
Early carnivorous mammal ancestors appeared shortly after the dinosaur extinction, about 66 million years ago.
The Full Story
True carnivorous mammal lineages became prominent after the end-Cretaceous extinction, around 66 million years ago. The ecological opening left by extinct dinosaurs allowed early predators to diversify rapidly. Over time, this produced groups such as cats, dogs, bears, and weasels. Their success is tied to the post-dinosaur expansion of mammals.
