Eclectic Echinodermata
For those interested in echinoderm diversity. This ranges from eocrinoids, crinoids, rhombiferans, blastoids, coronoids, diploporitans, parablastoids, echinoids, and all of the strange beautiful forms that came in between!

Yes, some certainly do. This is a Platycrinities species. The individual stem ossicles are oval and have a ridge running the long direction that is offset from the actual longest dimension of the oval. When they stack up this gives the twisted appearance. This fulcrum also allows the stem to flex.

Here’s a crinoid collected by a Dry Dredger years ago. It is now in my collection. It is Eucalyptocrinites elrodi from the Silurian Waldron Shale of Indiana. This is one of the less common species in this Formation. It is exceptional because the arms are preserved in place. Usually the arms and the upper part of the cup are missing. Scale bar is 10mm.

An excellent fossil! I was working in the Yale Peabody Collections several years ago and was rummaging around looking for hidden blastoids (as one does) and found a Eucalyptocrinites identified as a blastoid! I can see the confusion, the arms being folded up so neatly look similar to the blastoid ambulacra. The way these preserve is really spectacular.

Here’s a close up of an interesting fossil I posted earlier this week. It’s a bed of crinoid segments, presumably from different individuals of different ages, considering the various sizes that are evident. Some of them are stacked too, with smaller segments overlapping larger ones. #fossil

-
@sadie-mills – definitely a blastoid. It’s a Pentremites species! It is Carboniferous in age and is North American. I can maybe narrow it down if I see the specimen in person.

Pile of Pentremites! There are at least two different species in this pile maybe more. Pentremites is arguably the weirdest blastoid but also the most common. The tag on the box said Huntsville, Alabama.
Anyone love the weirder blastoids? My favorite is Cryptoschisma from the Devonian of Spain. #fossil

Here are some crinoid stem segments, with one showing what I’m guessing is a skin impression!
Nathan These all appear to molds to crinoid stems. Your skin is the mold of the external ornamentation of the stem.
Cool, thanks for the clarification!
That’s really cool!
Thanks!
