Those are really sweet; I'd be proud to display them!

I have never seen complete "baby" crinoids before...I guess that's where big ones come from;

wonder why I've never seen them?

I would think that they would be more fragile than the larger ones, but around that area, I have only found complete "baby" ones. In the same formation, I have found blastoids with brachioles and stems before, but they were extremely small. I even have one all the way down to the holdfast. Mine is the only one i have ever seen. strange.

Kudos to you for finding them. I might have overlooked critters that small. They are very nice.

Thanks. I do like them. they might be small, but when you are lookin for them, you will find them :D

Those are poor, pathetic girly-man crinoids. I suggest you send them to me so as to relieve yourself of the shame of owning them!

Seriously, nice specimens. Gorgeous.

And hey, fossil-friends! Found a nice echinoid chunk at Treasure Island beach this morning! Pics when I get home next week. Fossils on the beach! Does it get any better?

Don't confuse size in crinoids with maturity. Somewhere on the forum I have posted a pic of some adult crinoids, where the whole thing is smaller then a dime. I see that yours came out of the Ste. Genevieve, I am about 15 miles south of its type unit. The small crinoids that I have come out of the Girardeau Limestone, which is late Ordovician.

That is true, but the Platycrinites calyxes are normally about 1-2 inches in length. The first one is most likely a juvinile calyx. As for the other one, I am still not sure what it is, so I cant know for sure. There are crinoids that reach about the size of a dime in the St. Gen. I really liked your crinoids. Where are they from?

The pics that I posted are from northern Cape Girardeau county, not at the type locality, but close. The type locality has also produced small, mature crinoids. There is an entire publication on them, very technical on identifying species. The Girardeau limestone was originally classified as Devonian (I think), but was changed to Ordovician, largely through that study.

I'd move the pic over here for those who didn't see them, but can't figure out how to do it.

Thanks! Both photos are from a slab that was 2' x 3'. The one with the dime was used to practice for prep, only one partial was visible when I started. The picture w/o the dime is about 2/3 complete. They are:

Camarate crinoids

Late Ordovician

Girardeau Limestone
