JurassicParkCarnotaurus Posted July 26, 2018 Share Posted July 26, 2018 I found this on a beach in Mackinac Island in upper Michigan on Lake Huron. Just wondering if it’s a fossil, and if so what? Thanks! Link to comment Share on other sites More sharing options...
ynot Posted July 26, 2018 Share Posted July 26, 2018 Pictures are to blurry and can not make out any detail. Need a close up of some of the pieces. Darwin said: " Man sprang from monkeys."

Miocene_Mason Posted July 26, 2018 Share Posted July 26, 2018 I don’t know that area well but they look like fossils to me, perhaps little plant bits. “...whilst this planet has gone cycling on according to the fixed law of gravity, from so simple a beginning endless forms most beautiful and most wonderful have been and are being evolved.” ~ Charles Darwin Happy hunting, Mason Link to comment Share on other sites More sharing options...

Miocene_Mason Posted July 26, 2018 Share Posted July 26, 2018 7 minutes ago, Kane said: The deposits there will be late Silurian to early Devonian. In this case, I revise my guess to worn burrows. “...whilst this planet has gone cycling on according to the fixed law of gravity, from so simple a beginning endless forms most beautiful and most wonderful have been and are being evolved.” ~ Charles Darwin Happy hunting, Mason Link to comment Share on other sites More sharing options...

ynot Posted July 26, 2018 Share Posted July 26, 2018 Do they go all the way through the rock, or just on the surface? Side shots? Still hard to see detail. I am thinking crinoid or bryozoan bits. (but that is just a guess.) Darwin said: " Man sprang from monkeys." Will Rogers said: " Some of them didn't spring far enough."

Ludwigia Posted July 26, 2018 Share Posted July 26, 2018 Looks more like some kind of crystalline mineral deposit to me. The edges are too sharp for burrows. 4 Greetings from the Lake of Constance. Roger http://www.steinkern.de/ Link to comment Share on other sites More sharing options...
Oxytropidoceras Posted July 26, 2018 Share Posted July 26, 2018 Calcite pseudomorphs after rhomb-shaped gypsum / anhydrite in laminated mudstone. (I would guess that the mudstone is either a upper intertidal carbonate mudstone or lacustrine siliciclastic mudstone.) The formation of laminated mudstones with rhomb-shaped gypsum / anhydrite crystals that are later replaced by calcite often occurs in sabkha environments. sabhka - https://en.wikipedia.org/wiki/Sabkha Yours, Paul H. 6 Link to comment Share on other sites More sharing options...
