Rockjunkie717 Posted August 29, 2019 Share Posted August 29, 2019 I found these rocks between Ashland, Wisconsin and Little Girls Point in Michigan. There was so much rock hunting that day, I lost track of exactly where! Picture 2 (the tan colored) that's posted in the comments, is a coral fossil on the back. Shown is the front, I've never seen something like that before. Please share your knowledge, it's greatly appreciated! Link to comment Share on other sites More sharing options...

Pemphix Posted August 29, 2019 Share Posted August 29, 2019 Photo one is no fossil, just some sedimentary rock with calcite veins. Pic 2 is too blurry to tell, you need to choose a flat and unicolour pad. Put the piece on it and focus on the piece. Maybe some button coral or brachiopod....

This is the best I could do as far as picture quality, I'm sorry if it's not any better. The top and bottom "circles" are actually loops. Almost looks like a very unsemetric infinity symbol. The "fossil" is also covered in tiny vertical dots. Edited August 30, 2019 by Rockjunkie717 Link to comment Share on other sites More sharing options...
grandpa Posted August 30, 2019 Share Posted August 30, 2019 The new picture is some better. When I magnify the image, I see the cells (vertical dots) of what I believe is a bryozoan attached to a round stone. Link to comment Share on other sites More sharing options...
Rockwood Posted August 30, 2019 Share Posted August 30, 2019 Notice the very bottom edge. I think it defines the shape of the base of a fenestrate bryozoan colony. The fan pointing down as shown. Link to comment Share on other sites More sharing options...
Pemphix Posted September 2, 2019 Share Posted September 2, 2019 Yes, bryozoan seems to be a possibility... Link to comment Share on other sites More sharing options...
