Jones1rocks Posted December 22, 2017 Share Posted December 22, 2017 One that I initially thought was a coprolite, after photographing and zooming in, I believe I'm seeing a large group of tiny snails. Link to comment Share on other sites More sharing options...
Tidgy's Dad Posted December 22, 2017 Share Posted December 22, 2017 Yes, lots of little snails for sure! Couldn't be in a coprolite, could they? 2 Life's Good! Tortoise Friend. Link to comment Share on other sites More sharing options...
Nimravis Posted December 22, 2017 Share Posted December 22, 2017 They are and I am at a loss for there name- I believe Spirobis, but can’t recall. 2 Link to comment Share on other sites More sharing options...

Spirorbis is a recent little snail, I believe. 1 Life's Good! Tortoise Friend. Link to comment Share on other sites More sharing options...

I believe your thinking of microconchs. 2 hours ago, Tidgy's Dad said: Strobeus? Spirorbis is a recent little snail, I believe. Spirorbis is a serpulid worm that looks snail like I believe. Formerly, they were thought to be in Ordovicianto Jurassic deposits until it was determined that they should be called microconchs (some sort of structural difference). The affinities are to lophophores, possiblely tentaculid. 4 “...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...
Archie Posted December 22, 2017 Share Posted December 22, 2017 These certainly look like the spirorbis I sometimes see encrusting leaves in lower Carb/Mississippian freshwater limestones, cool to see them in a coprolite I hadn't thought anything ate them! 2 Link to comment Share on other sites More sharing options...
