Chalkdude Posted May 22 Share Posted May 22 I found this sample in southeast Kansas (Chautauqua co.). It has what looks to be crinoid arms on it but I’m not for sure. The arms look to be made up of small segments. Any helped would be appreciated. Link to comment Share on other sites More sharing options...
Ludwigia Posted May 22 Share Posted May 22 I think you're right, but let's let someone familiar with the fauna of your territory say something about it. How big is this? Greetings from the Lake of Constance. Roger http://www.steinkern.de/ Link to comment Share on other sites More sharing options...
Chalkdude Posted May 22 Author Share Posted May 22 The longest arms are just under 4 cm. Link to comment Share on other sites More sharing options...
Mochaccino Posted May 22 Share Posted May 22 Definitely crinoid arms. Geology of Kansas says Chautauqua co. is primarily Pennsylvanian with a sliver of Permian, so this is likely a Pennsylvanian crinoid. Without the calyx I don't think you can get much further than that. If you do find any calyxes or crowns they would be very interesting to see. https://www.kgs.ku.edu/General/geolSheetMap.html Link to comment Share on other sites More sharing options...
Chalkdude Posted May 22 Author Share Posted May 22 Sadly I found this many years ago and I didn’t know what I was looking at so never looked for a calyx. Thanks for all of the help though. Link to comment Share on other sites More sharing options...
