Really interesting. Looks like most of your specimens would be caught for sure by window screen. You mention that some species are common. Are all the species that you show common in the Castle Hayne Formation? With all the limestone debris, I would imagine that these are difficult to spot in the matrix especially the smaller specimens.

One of the Castle Hayne outliers that I used to collect almost completely lacked crinoids but all the other sites have numerous crinoids. Democrinus is the most common with Microcrinus second and Himerometra third. When I sort though Castle Hayne material I go very slowly and look at every grain. Not many shark teeth found this way but a good variety of invertebrates. I use a 1 mm. screen. I've tried smaller but it is too tedious.

Excellent presentation, Eric. I can appreciate your efforts in the photography of small finds. I occasionally find pieces of the Cretaceous comatulids here in Texas, and your topic has improved my understanding of them.

Very nice thread sir. This will definitely help others with IDs.

Pretty cool little crinoids.

I have yet to get my hands on Castle Hayne matrix.

Al Dente,

Interesting. I don't think I've seen crinoid specimens from NC before - particularly Eocene ones. I used to see Eocene ones from Oregon at shows.

I wanted to give this thread a bump. I search for it every now and then when I come across crinoids from the N.C. Castle Hayne.

Wonder moderators, could we pin this?

I think I might have some crinoids, so now I have a way to verify! Thanks so much, Al, for this amazing collection of fossils with descriptors, etc... awesome help for laymen!
