Ahead of my trip to the Arbuckle Hills area of Oklahoma, I had tried to find sites that may produce a Crinoid Lobolith for me. My finds in the field did not support the likelihood of success. However, back home, I discovered I had thrown this round object into my baggie full of fossils. Initially geode or bryozoa or coral seemed likely. But after looking at it in combination with some other site finds made me HOPE for a Lobolith from a Scyphocrinites. I will let you be the judge of my identification for I am completely novice to such a fossil. If any other views are warranted, just let me know. I forgot the ruler! The specimen is 3.5cm by 3.5cm by 2.5cm. There is strong mineralization as seen in this photo To the top of the picture, it appears as if a crinoid stem could have exited here. The "bottom" of the specimen is missing Close up photo shows some crinoidal pieces This is a drawing of what I hope I found At the collection site, I did find what appears to be a crinoid holdfast. So the two fit the photo above!!! Details verifying a crinoid holdfast are missing. But this specimen has the same mineral coating as the crinoid columnar pictured below. @Ironhead42 posted these photos of a crinoid lobolith found in the general area of my find. I feel they look similar. Thanks for any info/ identification!

One of the great things about hash plates is how much there is to see when you focus in close. I learned another great thing when I noticed a crack in this one from the marine, Viola formation of Pontotoc County Oklahoma. When I finally decided to bust it open it was like taking a whole new fossil hunt from the comfort of home. Most of it is the usual brachiopods and bryozoans but this caught my eye once I got a really close look. The scale is millimetres so this thing is tiny. I have no clue what it could be so help me out if you can.
