This was found along the fenceline of my side yard by my neighbor's dog when they were out for a walk this morning. Cleo (the dog) sniffed it out and dug it out from under some bushes, so it's probably been there a very long time. I have no idea about identification of animal skulls and teeth, but a Google search led me to this website forum. I am hoping someone here can tell me what we found. As you can see from the pics, this partial jawbone is almost the length of my husband's hand (he has large hands), and each tooth is at least the width of his thumb and about 2 inches long (taking into consideration how deeply each one extends into the bone structure itself). Anyone know what this is?
This is the upper jaw of a large herbivore. In a horse if the tooth is removed it is the same width all the way into the jaw, in a Cow the tooth has roots which taper. On the left of the top photo you can see the individual root holes for a tooth which is missing, which makes this a cow. The tooth on the right of both photos does not look worn at all which means it is a young cow/calf
