Mammoth upper molar
Mammoth upper tooth in the muck.
Two views of a mammoth "spit" tooth. Mammoths went through 5 or 6 sets of teeth in their life time. The teeth would form from the back of the jaw rather than underneath. Then, as a tooth wore out, it continued to move toward the front of the jaw like a conveyor belt, finally being spit out the front of the jaw as a new tooth took its place.
Two views of another mammoth spit tooth. This one shows wear against the side of the tooth caused by the replacement tooth pushing it forward and out of the jaw.
Lower jaws of a mammoth. This was an old animal on its last set of teeth.
