lmacfadden Posted March 29, 2013 Share Posted March 29, 2013 Found in a rock pile of river washed stone at theAusable River near Rock Glen, Ontario on March 28, 2013 Could this be part of a crinoid bloom? I do find quite a few crinoid stems there. The material around it is not soft so I could not wash it away. It is roughly 1" long ~Lise MacFadden - Arkona, Ontario, Canada Link to comment Share on other sites More sharing options...
Northern Sharks Posted March 29, 2013 Share Posted March 29, 2013 I'm thinking coral,not crinoid 1 There's no limit to what you can accomplish when you're supposed to be doing something else Link to comment Share on other sites More sharing options...
FossilDAWG Posted March 29, 2013 Share Posted March 29, 2013 I agree with Northern, it looks like a piece of an Eridophyllum or other similar coral colony. Also. I think the term you mean is "crinoid calyx", not "crinoid bloom". Crinoids are animals, echinoderms related to starfish and sea urchins, not plants.

I want to be sure to use the right terms. I need to do some more research before I post!!! ~Lise MacFadden - Arkona, Ontario, Canada Link to comment Share on other sites More sharing options...
Indy Posted March 29, 2013 Share Posted March 29, 2013 lmacfadden Its understood why you thought the fossil might be the arms of a crinoid as well as thinking crinoid is a plant ... Considering the basic anatomy of stalked crinoids Link Stem and what appears to be roots ... actually "holdfasts" As FossilDAWG mentioned ... Crinoids are animals. They are "filter feeders" ... Link There were many kinds of crinoids in the fossil record... including floating crinoids. 1 Flash from the Past (Show Us Your Fossils)MAPS Fossil Show Link to comment Share on other sites More sharing options...
