Top Trilo Posted October 9, 2020 Share Posted October 9, 2020 Is it on top of the rock or part of it? I found one similar and it turned out to be a blue lichen. “If fossils are not "boggling" your mind then you are simply not doing it right” -Ken (digit) "No fossil is garbage, it´s just not completely preserved” -Franz (FranzBernhard) "With hammer in hand, the open horizon of time, and dear friends by my side, what can we not accomplish together?" -Kane (Kane) "We are in a way conquering time, reuniting members of a long lost family" -Quincy (Opabinia Blues) "I loved reading the trip reports, I loved the sharing, I loved the educational aspect, I loved the humor.

Thecosmilia Trichitoma Posted October 9, 2020 Share Posted October 9, 2020 I've found a tiny specimen similar to this in German glacial till, but have no idea what it is.

LabRatKing Posted October 9, 2020 Share Posted October 9, 2020 Looks like Pholad bore holes from marine organisms that have filled in with silicates to me. Also called Gastrochaenolites.Is the rock glassy, as in silicate mudstone? 2 Link to comment Share on other sites More sharing options...
doushantuo Posted October 9, 2020 Share Posted October 9, 2020 once again,possibly orbicular granite. Link to comment Share on other sites More sharing options...
LabRatKing Posted October 9, 2020 Share Posted October 9, 2020 (edited) 3 hours ago, doushantuo said: once again,possibly orbicular granite. Good possibility, but with the photos provided and overall uniformity on the surface, a fresh face and or cut and polish would help with that line of thinking. This is pretty low density and a bit too perfect for orbicular granite in my opinion. Also igneous rock is relatively rare in that area. Sure it could be glacial in origin, but I feel more site data would be needed to confirm.
