Peto Lithos Posted December 8, 2016 Share Posted December 8, 2016 Limestone with coral. Not much distinguishable. 1 Link to comment Share on other sites More sharing options...
Rockwood Posted December 8, 2016 Share Posted December 8, 2016 It's a common misconception. The fossils are actually the small voids within the rock and not the rock it's self. It looks like broken bits of something, perhaps coral. Often they are bits of crinoids as well. Link to comment Share on other sites More sharing options...
Lake Rat Posted December 8, 2016 Author Share Posted December 8, 2016 Interesting. I did figure limestone but the coral? I'll have to do some reading. Didn't figure that for Lake Erie! Thank you! Link to comment Share on other sites More sharing options...

fifbrindacier Posted December 9, 2016 Share Posted December 9, 2016 Yes, perhaps coral, but without certitude. This part of the USA must have been under the ocean millions of years before the last glaciation. If i remember well, the great lakes of the north of the USA, formed whith the melted ice.

tmaier Posted December 9, 2016 Share Posted December 9, 2016 Might be just a calcite growth in limestone. I can't make out any structures that would make it be coral. Link to comment Share on other sites More sharing options...
