Pre-historic Mastodon bones from MI Mastodon, 1 vertebrae about 11 inches wide

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 which vertebrae this is but would be happy to receive thoughts. Can combine shipping.
