erose Posted May 15, 2013 Share Posted May 15, 2013 Two weeks ago I collected some crinoid material in Dayton, Ohio (Thanks HRGuy54!) I don't have much crinoid material other than lots of stems and a few of the most common calyxes. The material is tiny and partially disarticulated but it does include feeding arms and pinnules. In addition I found an edrioasteroid at the site. That was only my second one and I didn't even realize I had it until I was working on the strophomenids I collected there. The geology is Bull Fork Fm. (The fossil mix is indicative of both the Liberty and Whitewater Formations) That is Richmondian, Cincinantian Series (Late Ordovician). Take a look and throw me any ideas or suggestions for what I have found. Erich Link to comment Share on other sites More sharing options...

Shamalama Posted May 15, 2013 Share Posted May 15, 2013 I have no idea on the Crinoid but your edrio looks like an Isorophus. I find one every 100 or so Rafinesquina in the Whitewater Fm. -Dave __________________________________________________ Geologists on the whole are inconsistent drivers.

TMNH Posted May 16, 2013 Share Posted May 16, 2013 (edited) Maybe Reteocrinus for the one in the fist picture? http://www.uky.edu/OtherOrgs/KPS/images/reteo2.jpg Edited May 16, 2013 by TMNH Link to comment Share on other sites More sharing options...
danzimmerman Posted August 6, 2013 Share Posted August 6, 2013 Eric, The crinoid appears to be Iocrinus subcrassus. It is had to tell because the calyx is mostlycovered. It could be Cupuolcrinus, but I don't think so. Regards, DZ Link to comment Share on other sites More sharing options...
