GreatLakesLady Posted July 28, 2016 Share Posted July 28, 2016 Can anyone identify what these shapes are? I've noticed them poking out on the surface many of my rocks. The first is about 2.5 in. long, the other about .75 in. They were collected in Northern Michigan (near Lake Charlevoix) Thank you! Link to comment Share on other sites More sharing options...
CraigHyatt Posted July 29, 2016 Share Posted July 29, 2016 Maybe weathered cross sections of bivalve shells? 4 Info: Craig Hyatt, retired software/electrical engineer Experience: Beginner, fossil hunting less than a year Location: Eagle Pass, TX USA on the border with Mexico, hot dry desert Formation: Escondido, Marine, Upper Cretaceous Materials: Sandstone, Mudstone, Shale, Chert, Chalk Typical: Thalassinoides, Sphenodiscus, Exogyra, Inoceramus Reference: http://txfossils.com/Txfossils.html Link to comment Share on other sites More sharing options...
CraigHyatt Posted July 29, 2016 Share Posted July 29, 2016 Flip that rock around and take more photos if you care to. I think I see some more goodies there that one of the experts might identify. 1 Info: Craig Hyatt, retired software/electrical engineer Experience: Beginner, fossil hunting less than a year Location: Eagle Pass, TX USA on the border with Mexico, hot dry desert Formation: Escondido, Marine, Upper Cretaceous Materials: Sandstone, Mudstone, Shale, Chert, Chalk Typical: Thalassinoides, Sphenodiscus, Exogyra, Inoceramus Reference: http://txfossils.com/Txfossils.html Link to comment Share on other sites More sharing options...

Guguita2104 Posted July 29, 2016 Share Posted July 29, 2016 Hello! I agree with Craig on bivalve shells. On the bottom of the 1st pic I also see another fossil (maybe a bryozoan). Regards, 1 Link to comment Share on other sites More sharing options...

tmaier Posted July 29, 2016 Share Posted July 29, 2016 Also the specimen in the first image, lower left, has a nice looking bryozoa in it. 1 Link to comment Share on other sites More sharing options...
fifbrindacier Posted July 29, 2016 Share Posted July 29, 2016 (edited) I also agree, those are shells of bivalves and a bryozoa. If you take other photos, maybe could we tell you if it is an imprint of coral or no.
