Agaricrinites wortheni


Here is a picture of a fossil that appears to be an Agaricrinites wortheni crinoid plate. It was found in the Harrodsburg Limestone of Floyd County, Indiana USA. The fossil dates to the Mississippian Period.

Thanks to Kenny for the picture.

    Is this from the same crinoid with the oval shaped stem plates that also twist as they go up? Kind of like a helix?
