ydok Posted Thursday at 01:05 AM Share Posted Thursday at 01:05 AM I found this at Lake Michigan, and I'm not sure if it's something substantial or just geological. It is about 3 in/8cm long. The white patterning is slightly raised/textured and wraps around the circumference of the stone. Any help is appreciated. Thanks! Link to comment Share on other sites More sharing options...
Fossildude19 Posted Thursday at 11:41 AM Share Posted Thursday at 11:41 AM The first photo shows what could be something fossil related. Bryozoan? Coral?? Could just be a mineral crust, though. Looks like it has worn off of the rock, whatever it is.

debivort Posted Thursday at 11:45 AM Share Posted Thursday at 11:45 AM This feels more like an eroded metamorphic rock than a fossil to me. Not confident though. 1 Link to comment Share on other sites More sharing options...

Odd Rocks Posted Thursday at 06:02 PM Share Posted Thursday at 06:02 PM Could those grooves be critter burrows in carbonate hardground? This chunk broke off and was eroded in the lake to its present form? Link to comment Share on other sites More sharing options...
Mark Kmiecik Posted Thursday at 06:15 PM Share Posted Thursday at 06:15 PM (edited) The "lines" look more like sedimentary strata than fossils to me -- but I could be wrong. The first photo is what causes me to be not sure. Edited yesterday at 06:22 PM by Mark Kmiecik typo Mark. Fossil hunting is easy -- they don't run away when you shoot at them!
