I have, I think, incorrectly divined this as an American Carrion Beetle, but I don't think so based on photos here. I have seen these a few times on my farm in Dickson County, TN. This one was on the porch, on its back, and unable to flip over. Thanks.
This appears to be a beetle in the family Scarabaeidae, a very large assemblage comprising thousands of species. There also are some species of stag beetles (family Lucanidae) that can have a very similar appearance...
