Agassizocrinus? Crinoid Fossil

 

In 2012, I posted a crinoid calyx fossil which was identified as a Phanocrinus nitidus. Recently, I revisited this fossil and took some new pictures of what might be an Agassizocrinus. The matrix it is in also contains a very nice Archimedes bryozoan and an unknown brachiopod. The specimen was found in southern Indiana, USA and dates to Mississippian Period. The crinoid is about 3 cm in length.
