6.1" Feathery Starfish Fossil With Carpoids & Trilobite Heads

This is a very unusual fossil starfish from the Tiouririne Formation near Kaid Rami, Morocco. All five of the arms are covered in feathery spines. When I was in Morocco this past November I was able to acquire a few of these rare starfish fossils which I have not previously seen. The detail is amazing the the orange limonite preservation is quite striking. This huge, starfish measures 6.1" and it is associated with several carpoids and partial trilobites.
