Pre-historic Mastodon Bones from MI Mastodon, hip bone ? about 7 x 7 inches.

Description

The mastodon bones I have listed (see my other listings) are bones that have come out of the pond in our backyard. The paleontologist from U of M said they are from a female mastodon about 10-12,000 years ago. I have not been able to find a museum interested in them, so here they are on EBay! I also don't know exactly what bone this is but would be happy to receive thoughts. Can combine shipping. The Etch marks on this bone are thought by the paleontologist to be caused by animals gnawing on it. (I was hoping he would say it was markings from the pre-historic hunters who probably slaughtered the mastodon in our backyard when it was a wet lowland.)
