edteach Posted December 26, 2018 Share Posted December 26, 2018 Went hiking again this Xmas day. My wife and I found these on top of the ground in lime stone formations in clay around the huge cliffs of limestone. What are they? The rings with holes look like others I found on line called tub worms. Thanks 2 Link to comment Share on other sites More sharing options...
Kane Posted December 26, 2018 Share Posted December 26, 2018 These are crinoid stems/columnals. The second image looks like it has the arms of the holdfast, which is pretty cool. 8 ...How to Philosophize with a Hammer Link to comment Share on other sites More sharing options...

Wolf89 Posted December 26, 2018 Share Posted December 26, 2018 Yup, crinoids. They are interesting little things Link to comment Share on other sites More sharing options...
Bronzviking Posted December 26, 2018 Share Posted December 26, 2018 I agree with the others, crinoids. Very interesting branching arm pattern, nice find. Crinoids are marine animals that make up the class Crinoidea of the echinoderms (phylum Echinodermata). The name comes from the Greek word krinon, "a lily", and eidos, "form".[3][4] They live in both shallow water[5] and in depths as great as 9,000 meters (30,000 ft).[6] Those crinoids which in their adult form are attached to the sea bottom by a stalk are commonly called sea lilies.[7] The unstalked forms are called feather stars[8] or comatulids. https://en.wikipedia.org/wiki/Crinoid 2 Link to comment Share on other sites More sharing options...
Herb Posted December 26, 2018 Share Posted December 26, 2018 looks like crinoid stem pieces and a hold fast to me.

The Amateur Paleontologist Posted December 26, 2018 Share Posted December 26, 2018 I agree with crinoid remains, and I'm sure about that the branched thing in the second picture is a holdfast (from the base of the crinoid, was used for remaining fixed/attached to the substrate ) -Christian 2 Opalised fossils are the best: a wonderful mix between paleontology and mineralogy!
