Ksgal Posted March 30, 2019 Share Posted March 30, 2019 I was out metal detecting and found this little rock. I'm sure its probably not a fossil, but what a perfect circle! Anyone happen to know what caused this? Its the size of a penny. Link to comment Share on other sites More sharing options...

Tidgy's Dad Posted March 30, 2019 Share Posted March 30, 2019 Yes, a crinoid columnal, or stem segment like one of the ones below was fossilized there but then eroded away leaving this mold behind. 2 Life's Good! Tortoise Friend. Link to comment Share on other sites More sharing options...
abyssunder Posted March 30, 2019 Share Posted March 30, 2019 That little nice one looks like a crinoid stem remnant. We are looking at a crinoid columnal facet or an imprint of one, or the printed infill sediment between two columnals, in my thinking. 1 " We are not separate and independent entities, but like links in a chain, and we could not by any means be what we are without those who went before us and showed us the way.

Ksgal Posted March 31, 2019 Author Share Posted March 31, 2019 Hey WOW! I had no idea it was actually a imprint or fossil. I just knew it was weird to find a rock with a perfect circle. Thank you all for your wisdom!! Link to comment Share on other sites More sharing options...
