    Crinoids - Fifeocrinus Arms a.jpg

    From the album: MY FOSSIL Collection - Dpaul7

    Fifeocrinus Crinoid Arms SITE LOCATION: Chesterian Zone of the Bangor Limestone Formation in northern Alabama TIME PERIOD: Mississippian Period (ca 325,000,000 yrs old) Data: Crinoids are marine animals that make up the class Crinoidea of the echinoderms (phylum Echinodermata). The name comes from the Greek word krinon, "a lily", and eidos, "form". Crinoids are characterised by a mouth on the top surface that is surrounded by feeding arms. They have a U-shaped gut, and their anus is located next to the mouth. Although the basic echinoderm pattern of fivefold symmetry can be recognised, most crinoids have many more than five arms. Crinoids usually have a stem used to attach themselves to a substrate, but many live attached only as juveniles and become free-swimming as adults. Kingdom: Animalia Phylum: Echinodermata Class: Crinoidea Order: †Cladida Family: †Plectorthidae Genus: †Fifeocrinus

    stratigraphic problem.

    Hi. Around year ago I was exploring the area around Lough Hackett 20 km north from Galway. I found few fossils on the shore with much different fauna than typical late Visean fauna in Co. Galway. The main problem here is stratigraphy. It's similar to british Avon group of Mendips. I think all of them are Tournaisian. Fig1. Large piece of iron-stained black crinoidal limestone.

By far the longest crinoid stem I've seen and collected from central New York. Matrix was weathered and unstable. Fossil was removed in eight pieces and reassembled.

    Crinoids
  7. sLast weekend I took a four day trip to Kentucky to see family; parents, sister, brother-in-law, and nephew. While there arranged to get together with Herb from the Forum to collect Mississippian Age fossils which I hadn't done before. There are no fossiliferous Mississippian Age deposits in New York and the nearest are in Western Pennsylvania hours away, so this looked like a good opportunity to add some marine fossils from that age to my collection. Fortunately where my family lives is in an area of marine Mississippian deposits. On the way to our rendezvous with Herb in E-Town (Elizabethtown) my nephew and I stopped at a road cut in Leitchfield that he knew about and had seen other collectors collecting at. Fossils were eroding out of the hillside by the score and could be picked up right off the ground free of the matrix. Collected a number crinoid stems, bryozoans, and small brachiopods. After an hour, we continued on to our meet up with Herb. My nephew had already met Herb at a collecting site. We continued on to another road cut collecting site about forty minutes away. Again, fossils were eroding out of the hillside and could be picked right up free of the matrix. Prior to this I had no blastoids in my collection but in just an hour and a half I'd collected fifteen plus more brachiopods, crinoid stems, and some more bryozoan specimens. We then returned to the first place in Leitchfield where my nephew and I visited earlier. Found more specimens including a number of crinoid calyxes, a couple blastoids, and a few more brachiopods and bryozoans. I'll have to study to learn the IDs of these specimens. All in all a great day and Herb was wonderful to collect with and very generous and knowledgeable besides. Hope we get to do this again next year. Oh, and by the way, the family visit went well too.
