Here are a couple of new additions to my collection. I’ve been fascinated with crinoids lately, and am seriously considering them as an area of focus for my collecting and study. Here is a Macrocrinus mundulus from the Edwardsville Formation (Mississippian) of Indiana. The prescence of most of the arms, cirri, and anal sac are what drew me to the piece. There is an arm curled up to the right of the stem; presumably broken away from the main specimen. As well as a very small calyx in the upper right corner. I also picked up this specimen of Glossopteris browniana. It’s from the Illawarra Coal Measures (Permian) from Australia. I’m a sucker for plant fossils. This one was a decent specimen that I picked up at a good price.

I think this calyx I found today and prepped (on the left) is a Macrocrinus konincki, but I've only found one other one. I typically find Macrocrinus verneuilianus (on the right), so anyone familiar with crinoids please let me know what you think! Thanks, Jackson

Another search for Burlington Formation crinoid fossils
Jackson g posted a topic in Fossil Hunting Trips
Today's the first nice day we've had all week here, and on top of that lucky I got the rest of the week off of work. I decided to go out and search for crinoids for a few hours. Last time I went out I did recon on a favorite spot of mine, and I would say that effort paid off today. I ended up hitting a new section at the area that is usually underwater. Well anyway, heres the finds. Only about half are cleaned up. Starting with Azygocrinus rotundus Macrocrinus verneuilianus Uperocrinus pyriformis Actinocrinites multiradiatus Eutrochocrinus christyi Crinoid calyx (chert layer, unidentifiable) Uperocrinus sp? I also found a very unusual blastoid steinkern with an unusually long thin body. It's from Burlington chert, and I believe it to be a Metablastus lineatus steinkern. Will never know though. Well that's all I dragged home today. Hope you all have had a great Thanksgiving today if you celebrate it.- 7 replies
