New Members hoverchocs Posted August 9 New Members Share Posted August 9 (edited) Hello, I was handed a pile of rocks found on a trip to Lake Michigan. My husband’s coworker passed on a box of rocks from Lake Michigan. I think there are a few fossils but am not sure. May I have some assistance with confirmation and/or identification please? Some of the pictures are the rocks rotated for more detail. Thank you for lending me your knowledge.

Fossildude19 Posted August 9 Share Posted August 9 First item looks like a coral. Not seeing any trilobites here, though.

Ludwigia Posted August 9 Share Posted August 9 I agree with coral for 1. 6,7 and the last one appear to have cross-sections of somethng or other, but can't tell what. The others have no fossils in them. Greetings from the Lake of Constance. Roger http://www.steinkern.de/ Link to comment Share on other sites More sharing options...
Bullsnake Posted August 9 Share Posted August 9 @Fossildude19 @Ludwigia I may be off-base, but on the first item I think I'm seeing distinct segmentation. I can't accurately count the segments but my first thought was maybe a chiton, or perhaps cephalopod. I'm hesitant to doubt you guys, though.

Isotelus2883 Posted August 9 Share Posted August 9 They are the tabulae which can look like segmentation. 1 2 Link to comment Share on other sites More sharing options...
New Members hoverchocs Posted August 9 Author New Members Share Posted August 9 My husband felt like he was seeing the segmentation as well. Can you explain what he is seeing? He would like to understand what he is looking at. He sees the edges with the fringe and then what looks like segmentation down the “top” and some on the back. Is there a specific type of coral this is that he could do some internet sleuthing to see what it would look like? Link to comment Share on other sites More sharing options...
Kane Posted August 9 Share Posted August 9 You could look up rugose coral. This has been eroded to show some of the inner structure. It may not be possible to identify it further than that without more precise provenance and possibly even using acetate peels. 1 ...How to Philosophize with a Hammer Link to comment Share on other sites More sharing options...

But the above image shows what I am seeing. 1 Tim - VETERAN SHALE SPLITTER VFOTM --- APRIL - 2015 IPFOTM -- MAY - 2024 _________________________________________________________________________________ "In every walk with nature one receives far more than he seeks."

debivort Posted August 9 Share Posted August 9 I think the last one might be a cross section through a crinoid stem Link to comment Share on other sites More sharing options...
