Jdeutsch Posted January 28, 2012 Share Posted January 28, 2012 A while back I posted some images of geodized fossils on the ID section Indy posted this nice link http://www.relic-master.com/geodized_fossils.htm There was a particular image in my posting where there were questions raised by the forum as to whether it was a crinoid or a blastoid. I did some searching on the web since this wasn't obvious to me, but my searching just raised more questions. So now I.m asking the group- A) if one finds an isolated stem - how do you know if it is blastoid, crinoid or something else? Next- with the geodized fossil heads, are there features to look for that might seperate out crinoid from blastoid?- I've attached a few examples Link to comment Share on other sites More sharing options...
Herb Posted February 5, 2012 Share Posted February 5, 2012 Except in rare exceptions do blastiods get over 1.5" long, most in the Mississippian are 0.5 to 1" long (at least in KY).
