$200.00 FO512b    Here is something different from the Rock Shed's fossil department.  This is a single very well preserved above average quality Crinoid specimen.  It measures 10" x 6 1/2" x 1" and has not been polished.  The Crinoid has one very detailed calyx (flowery head) with 1" of stem attached.  Since this was once part of an ancient sea floor many crinoid stems can be seen on the back from when the specimen was sawed and prepared for display.

Crinoids, also known as sea lilies or feather stars, are marine animals that belong to a class of Echinoderms.  They lived in both shallow and deep water.  They are characterized by a mouth on the top surface that is surrounded by feeding arms.  Crinoids usually have a stem used to attach themselves to a substrate, but many live attached only as juveniles and become free-swimming as adults. There are only a few hundred known modern forms, but crinoids were much more numerous both in species and numbers in the past. Some thick Limestone beds dating to the mid- to late-Paleozoic are entirely made up of disarticulated crinoid fragments.

Ammonites are extinct members of the cephalopod group of mollusks. Only a limited number of species have survived to the present day which includes the squid and the chambered nautilus. Ammonites had a multi-chambered shell, and added more chambers as it grew, always living in the outer chamber.  They lived in the Cretaceous period some 63 to 130 million years ago.

These Moroccan fossils are among the oldest cephalopods.  They were abundant during the Paleozoic era some 350 MM years ago and now make up the Atlas Mountain range of central Morocco. There were two nautiloids forms present in the Moroccan Devonian sea.  The Goniatites is an extinct relative of the Ammonites,  it possessed an external shell, which is has a spiral form with internal chambers. The Orthoceras was straight shelled cephalopod with the internal chambers. They were related to the modern day chambered nautilus and the squid.
