Two calyces from Michigan

[Eastonian]

Last weekend, I spent a day at one of my favorite hunting grounds in Alpena, Michigan, on Lake Huron: Partridge Point. (Thunder Bay Formation, Devonian.)

There's a lot of fossiliferous matrices in limestone. You also find lots of crinoid columnals. Last year, at this location, I found my first -- and only -- blastoid (Placoblastus obovatus).  

This time, I walked away with two calyces: I believe the first one pictured here (two images) is Megistrocrinus depressus; the second looks like Dolatocrinus asterias. Have I identified these correctly?

I'm headed up there again this summer some time to collect.  Love it up there.

The ID for Dolatocrinus asterias looks good.  Megistocrinus depressus is not listed in Ehlers & Kesling:

Wow! That is beautiful! I have never seen any like that. I live in a Cretaceous environment.

 

I have had limited exposure to blastoids, but echinoid urchins are my 2nd favorite class of fossils. So I think those are pretty cool.

Sorry I can’t help with ID.

The first one looks to be Megistocrinus concavus.  There is a photo of a cleaned one on my web site http://www.crinus.info/crinoids/data/meg12.htm
