This is a multiple plate of detailed Eocrinoids (Ascocystites sp.) collected near Kaid Errami, Morocco. The reddish/orange coloration due to the oxidization of iron pyrite is very beautiful and showy.
Comes with an acrylic display stand.
Eocrinoids were an early group of echinoderms that lived between the Early Cambrian and Late Silurian periods. They had a stalk which attached them to the bottom of the ocean via a holdfast and were benthic suspension feeders which used their arms to move particles of food towards a mouth. They are believed to be ancestral to many other groups including crinoids and blastoids.
