It makes a "clink" when tapping it on glass or metal. Or with a finger nail. Found on a river bed in Wisconsin.

I don't see tree rings, and the shape looks correct for a split bone missing the marrow.

Looks like bone to me

I'd guess it's petrified bone.

Looks like a dog chew-- groove down the centre doesn't look natural, it looks molded/pressed. Something similar to this, but long weathered: https://pettoba.ca/products/rice-bone-all-natural-daily-dental-chew-for-dogs-whimzees%C2%AE?srsltid=AfmBOoohVgThiUMb_dpn54T6TA6Cn525z4D1otI4tFKRKIOB_OR4NVe1
