I collected this disarticulated cystoid from the Kimmswick Formation (Late Ordovician) in eastern Missouri. Cystoids are well outside my wheelhouse, so I was hoping someone here might be able to help me narrow down an ID, if one can be made at all from what's present. Thanks for any help.

Echinoderm identification help please! Polished cross-section in the Kimmswick Limestone (Late Ordovician: Katian; Missouri, USA) used as facing stone at Missouri Botanical Garden. Possibly the paracrinoid Implicaticystis (once known as Comarocystites)? Specimen is ~25 mm across.

Illusory erect spines(?) on a Kimmswick receptaculitid
pefty posted a topic in General Fossil Discussion
UPDATE: These seem to just be weirdly incomplete cross-sections through ordinary cylindrical meroms. ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ This weekend in the Kimmswick Limestone in eastern Missouri (Pike County) I saw plenty of receptaculitid algae, mostly of genus Fisherites. But one cross-section has a feature I've never seen before: a fringe of what look like erect spines on the external surface. Can someone point me to a reference for understanding this feature functionally and/or taxonomically? I've looked in the usual places but I don't seem to be finding anything about spines. (If I were a vertebrate paleontologist, I would be saying they were feathers and proclaiming receptaculitids' "Sinosauropteryx moment.") Thanks.

Eastern Missouri / Southwestern Illinois Fossil Localities
Osteodontokeratic posted a topic in Member Introductions
Hello Fellow Fossil Officienados, I just recently retired and was wondering if anyone in the Greater St. Louis area would be interested in going on some fossil collecting expeditions? Been collecting in the area for 4 years and know there are a lot more places to go to find some quality &/or unique specimens than where I have been. On occasion, to the safer road cuts, I started taking my oldest grand child, age 8. He is getting the bug! So in addition to any more remote locales that I am willing to go to, would also like to know if anyone knows of a place that is relatively safe for an 8 year old. Have taken him so far to a Decorah site on Highway M & a Fern Glen site off I-55, in Jefferson Co., Missouri. BTW, I am a member of EMSP, ESCONI, and formerly of SIESC. Am also interested in going further afield. Recently visited the I-64 road cut near Sulphur, IN. Take care, ODK
