Arthropoda-is-my-game Posted June 28, 2019 Share Posted June 28, 2019 I found three of these fossils in a small area at my local creek where I collect fossils. Two of them were found by themselves but one of them is still inside the matrix accompanied by bryozoans and crinoid segments. I have no idea what they are or could be but they resemble teeth. They were found in Crittenden County Kentucky if that helps any. 1 Link to comment Share on other sites More sharing options...
TqB Posted June 28, 2019 Share Posted June 28, 2019 They look like crinoid spines - probably Carboniferous. 6 Tarquin Link to comment Share on other sites More sharing options...
Manticocerasman Posted June 28, 2019 Share Posted June 28, 2019 I lso think some crinoid parts. 5 growing old is mandatory but growing up is optional. Link to comment Share on other sites More sharing options...
erose Posted June 28, 2019 Share Posted June 28, 2019 Definitely crinoid spines. These would have been poking out like aa crown of thorns from the calyx or sometimes the top of the anal sac. and with that may I suggest doing some research on crinoid morphology... 5 Link to comment Share on other sites More sharing options...
Arthropoda-is-my-game Posted June 28, 2019 Author Share Posted June 28, 2019 Thanks! They’re definitely crinoid spines now that I’ve done research. You’re help is much appreciated! Hopefully this is a step towards finding a full crinoid. Speaking of that does anyone advice for finding full crinoids? Is it even possible in this area? Also I found these amongst the crinoid stems and I have no idea what they are either Link to comment Share on other sites More sharing options...
Archie Posted June 28, 2019 Share Posted June 28, 2019 Those look look like plates from the Carboniferous echinoid Archaeocidaris, nice finds! 2 Link to comment Share on other sites More sharing options...

I agree, with a mamelon on the top one, under a larger one. The bottom one could also be a crinoid plate? 2 Tarquin Link to comment Share on other sites More sharing options...
Arthropoda-is-my-game Posted June 28, 2019 Author Share Posted June 28, 2019 Here’s one I found separated from the matrix. It broke so it’s not complete unfortunately Link to comment Share on other sites More sharing options...

Area around Maysville, Ky. 2 Mark. Fossil hunting is easy -- they don't run away when you shoot at them! Link to comment Share on other sites More sharing options...

It broke so it’s not complete unfortunately I guess crinoid plate on that one, doesn't look like echinoid. So there may just be one Archaeocidaris plate (with the mamelon) in the previous photo. 2 Tarquin Link to comment Share on other sites More sharing options...
