DanO Posted July 2, 2016 Share Posted July 2, 2016 Just looking for any other help identifying. Was cleaning some sediment and found them. Pretty sure they are Crinoids just haven't seen this flower like pattern often. Unsure on the original location of the sediment though Link to comment Share on other sites More sharing options...
doushantuo Posted July 2, 2016 Share Posted July 2, 2016 (edited) yep,fairly typical shapes there good article by SD.: http://cdn.palass.org/publications/palaeontology/volume_27/pdf/vol27_part4_pp825-841.pdf Edited July 2, 2016 by doushantuo Link to comment Share on other sites More sharing options...
Kane Posted July 2, 2016 Share Posted July 2, 2016 You do have some crinoid sections here as well as some bryozoan fragments. The crinoid stems were fairly diverse in the Devonian, with some of them having raised nubs and spikes. I can't make out from this picture the smaller thin pieces at the lower right, but they might be bactrites. Good stuff! ...How to Philosophize with a Hammer Link to comment Share on other sites More sharing options...

fifbrindacier Posted July 2, 2016 Share Posted July 2, 2016 I agree with kane's identification of crinoids and bryozoans. Nice find.

DanO Posted July 2, 2016 Author Share Posted July 2, 2016 Thanks for the info. I just started going through it all. Perhaps I'll post some photos of my whole find when I'm done. Hopefully I'll be able to some great specimens like yours someday Kane Link to comment Share on other sites More sharing options...
tmaier Posted July 2, 2016 Share Posted July 2, 2016 Here's a fairly typical selection of crimoid sections I pulled from my last trip to show some of the varieties. Excellent display of crinoid stem diversity. Here is one that most people have never seen. I think it is in the genus Platycrinus. It is oval instead of round, and has a ridge running through it (first photo, #5). The whole column rotates and spirals (second photo, #3). Photos are very old, and not too good quality.

Guguita2104 Posted July 2, 2016 Share Posted July 2, 2016 My vote also goes to crinoids and bryozoans (maybe Fenestella sp.). Regards, Link to comment Share on other sites More sharing options...
