Walton Posted August 13, 2022 Share Posted August 13, 2022 Hello all Apologies in advance for the potentially stupid question, but I promised my 9 year old (fossil hunter/general geology fan) son that I'd get to the bottom of this! During a river walk today, we came across an exposed rock that had some weird line patterning on it, that does admittedly look a little fossil-y. However, elsewhere on the rock there are lots more of these patterns in more random formations, so while I'd love it to be a little more interesting, I suspect it's just some unusual rock form. Anyway, you lot are the experts, so please advise! Thank you! P.S. rock found in central Scotland, UK. Link to comment Share on other sites More sharing options...

Walton Posted August 14, 2022 Author Share Posted August 14, 2022 Apologies that I didn't add any scale here! The highest was c. 50cm wide, so fairly large. Link to comment Share on other sites More sharing options...

Their shells have a slightly delaminated nature is the thing that made me go there. Link to comment Share on other sites More sharing options...

It was a big boulder and the patterning was probably c.30cm long Link to comment Share on other sites More sharing options...
debivort Posted August 14, 2022 Share Posted August 14, 2022 crinoid frond? Link to comment Share on other sites More sharing options...
mr.cheese Posted August 14, 2022 Share Posted August 14, 2022 I would be inclined to lean towards some kind of crinoid too Link to comment Share on other sites More sharing options...
Rockwood Posted August 14, 2022 Share Posted August 14, 2022 It would be a big help to see it dry in that case. Link to comment Share on other sites More sharing options...

Bringing Fossils to Life Posted August 15, 2022 Share Posted August 15, 2022 I thought crinoid, too. Link to comment Share on other sites More sharing options...
