piranha Posted June 26, 2013 Share Posted June 26, 2013 The helicoplacoids are certainly bizarre early echinoderms. Attached are figures of similar examples of this clade in a contracted and expanded state plus a reconstruction of another one that was attached to the cephalon of a Nevadella trilobite! For anyone interested there is an excellent free PDF detailing the life habit and morphology of these unusual echinoderms: LINK Wilbur, B.C.

Shamalama Posted June 27, 2013 Share Posted June 27, 2013 What a fascinating critter, thanks for sharing! -Dave __________________________________________________ Geologists on the whole are inconsistent drivers. When a roadcut presents itself, they tend to lurch and weave. To them, the roadcut is a portal, a fragment of a regional story, a proscenium arch that leads their imaginations into the earth and through the surrounding terrain. - John McPheeIf I'm going to drive safely, I can't do geology. - John McPheeCheck out my Blog for more fossils I've found: http://viewsofthemahantango.blogspot.com/ Link to comment Share on other sites More sharing options...
