YorkRich Posted April 19, 2018 Share Posted April 19, 2018 My partner and I found this on the beach at Runswick Bay (near Whitby, Yorkshire, UK). It's about the size of a golf ball. Given the concentric layers it might be geological. However, we wondered if it might be coprolite? There are hundreds of little white flecks embedded within that could plausibly be tiny fish bones? We are novices and any advice would be appreciated. Thanks! Rich Link to comment Share on other sites More sharing options...
ynot Posted April 19, 2018 Share Posted April 19, 2018 Welcome to TFF! Looks like a concretion. 1 Darwin said: " Man sprang from monkeys." Will Rogers said: " Some of them didn't spring far enough."

MeargleSchmeargl Posted April 19, 2018 Share Posted April 19, 2018 Concretion. A really interesting one at that. What minerals cause it to be blue...? Every single fossil you see is a miracle set in stone, and should be treated as such. Link to comment Share on other sites More sharing options...
GeschWhat Posted April 19, 2018 Share Posted April 19, 2018 +1 for concretion on the outside. The interior looks like a shell hash. I would bet the blue color is just the lighting.

fifbrindacier Posted April 19, 2018 Share Posted April 19, 2018 Nice blue, i also wonder to what it is due ? "On ne voit bien que par le coeur, l'essentiel est invisible pour les yeux." (Antoine de Saint-Exupéry) "We only well see with the heart, the essential is invisible for the eyes." In memory of Doren Link to comment Share on other sites More sharing options...

I think it's due to the camera exposure. +1 for concretion 1 Greetings from the Lake of Constance. Roger http://www.steinkern.de/ Link to comment Share on other sites More sharing options...
