The last time I was on a fieldtrip to Brownwood, Texas, I collected a lot of the abundant crinoid stem sections that seemed to laying all over the ground wherever we stopped. I tried to collect as many of the solitary segments as possible but they were far less abundant than the column sections. Years ago, someone was telling me that there were sites where the solitary columnals could be collected by the handful. I am hoping that someone on the Forum can steer me towards information about potential sites like that. Now that I am retired, I have become a Docent at the Houston Museum of Natural Science and I like to park myself in the fantastic new paleo hall next to a display of a large beautifully prepared crinoid, holding a section of consolidated Pennsylvanian seafloor bed covered with crinoid stem pieces, bryozoans, and brachiopods that the children can handle. If they hang around long enough to listen to my spiel about the age of the crinoids I reward them with a small ziploc bag with a crinoid columnal in it. They really love taking a 300 million year old fossil home with them. This is why I want to find a place to get a large quantity of single columnals, or failing, that short columns with a small diameter. Any help would be greatly appreciated.
