This is one of the burying beetles in the genus Nicrophorus (in the carrion beetle family Silphidae), specifically N. tomentosus, as told by the golden hair on the top of its thorax. Burying beetles (aka "sexton beetles") are well-known for giving people a start by moving the dead bodies of small animals across surfaces that won't accomodate burial of the animal. Sometimes only one beetle works the carcass from beneath, giving the illusion of an animate corpse! Once the body is in a suitable situation, the beetle(s) dig beneath it, sinking it into the ground. A chamber is built underground, and the carcass is skinned and molded into a "meat ball." Atop the ball, the female deposits eggs. She feeds the larvae that hatch until they can feed themselves, but she stands guard, sometimes with the help of a male, for much, if not all, of the life cycle of her offspring.

I would say that it is in fact a Silphid beetle of the genus Nicrophorus.

They love the carcasses!
