Found this what I believe to be a partial trilobite about 10 years ago on the Dead River Basin in Michigan's Upper Peninsula after a dam broke and there was a flood. I'm curious to identify it positively as a trilobite as I was told it it was. To age it. And I know you don't appraisals but I'm curious if it might be worth something. I tried to take pictures according to the directions if there's something better I can do please comment. Thank you in advance.
