This is a very striking crinoid plate from the Mississippian of Indiana. On the left side of the plate is a beautiful Decadocrinus tumidulus. This type of crinoid is known for the shape of its arms - the arms look like jaws with teeth in them!This 3-dimensional specimen exhibits wonderful detail and an extremely long stem. On the right side of the plate is a large Scytalocrinus decadactylus. This inadunate crinoid has a small, bowl-shaped cup and very stout, uniserial arms. The plate structure is easily seen, and the arms display very well. A long, straight stem is still tightly attached to the cup. Both fossils have great color and contrast and are well positioned on the rectangular plate of siltstone. This is a great specimen of Decadocrinus and Scytalocrinus preserved together on the same piece.
