Newbie Lake Michigan fossils

[chemistographer]

Hi everyone,

 

I just got to spend a couple days looking for fossils at Lake Michigan and came across a few that I couldn't identify. In addition to loads of Petroskey stones and Charlevoix stones, I came across the attached rock. Any thoughts on what may have been captured here? The stone is about 4 inches across at the longest (top to bottom in the figure). Location: Charlevoix, Michigan.

Just did a google image search to compare - spot on! Thank you so much for satisfying my curiosity. Hoping I can keep finding some cool things out there!

Yup, keep looking and you're certain to find something else interesting.

Hello, and a very warm welcome to TFF from Morocco.

commonly called fossil hash stones in my area. Sometimes put in a rock tumbler and come out nice, but they may break if not done separate from hard stones.
