Found a Skull - A Rabbit?

We found this skull, which we at first thought to be a bird's, on a stone beach at Lake Byllesby on Saturday. It has what appears from the side to be a yellow, extremely hooked beak something like that of a raptor.

But when seen from the front, it doesn't look like a beak, it looks like two curved front teeth. From searching Google images of "rabbit skull," I think that's what we might have, but I am very open to other more expert opinions.

Below is the underside.
