A jaguar has a broader head and wider jaw compared to a leopard. It also seems that jaguars have more black around their eyes, nose, and mouth, giving it a tougher look.

Jaguars tend to have larger rosettes with spots in the middle, the leopard has plain rosettes with no spot in the middle. And leopards aren't as stocky as the jaguar.

Both are big cats . I am talking about the bone structure that allows them to roar . I could not tell just buy looking at the skull but an experienced person could .

I know that jaguar and leopard have different spotted pattern. And they also live in different area, leopard>>asia&africa and jaguar>>america. But if you only looking the skull, can you identified what species it is?
