PostSubject: Canids    Wed Oct 19, 2016 7:48 pm

If we talk about modern animals, I think canids are my favourite. Grey wolf, particularly. And Canis dirus, is my favourite extinct canid.

What I don't understand is why C. dirus became extinct? Some people say it is to be caused by the extinction of their megaherbivore prey. But there is a study of the dental microwear on tooth enamel of all of the carnivore species from Rancho La Brea, California, including dirus, and the evidence suggests that these carnivores were not food-stressed just before extinction and that carcass utilization was less than among large carnivores today.

Was it caused by competition with other species including humans?
