I believe this is half of the lower jaw bone. Given the wear on the jaw, this wasn't a young animal when it died. I found a deer jawbone on a hiking trail in shanahan ridge. It was not as clean as this one. Sam age 8 Sam McGill Monday, February 26th, 2007 at 17:25:27 I found a jawbone but didn't know it was a deer bone. When I saw your bone it looked just like mine does. sofia Sunday, January 6th, 2008 at 11:35:53 we found a deer's lower jaw bone with a baby tooth still clinging over the adult tooth at a camp on the scout leaders private property and were told we could keep it. Christopher & Shawn Thursday, June 26th, 2008 at 09:27:09 We found a jawbone at Western Regional Park, Glenwood MD, by the play area. We weren't sure what it was until we saw your picture. Victoria age 10 & Amber age 8 Saturday, March 10th, 2012 at 15:51:57 While visiting Bar Harbor ME we went Seal Harbor and walked on the beach looking crabs and shells, I found a jaw bone. We figured out it was the jawbone of a deer (gender unknown). Ryan Wednesday, April 25th, 2012 at 07:36:59
