Few very small free swimming organisms. Originating in the 150 million year old Jurassic Solnhofen Lithographic Limestone deposits near Bavaria, Germany, these pelagic (free-floating) comatulid crinoids are known as Saccocoma pectinata.

They occur in seven separate layers deposited over ½ million years, and are found dispersed among an vertebrate and invertebrate organisms.

As a member of subclass Articulata, Saccocoma are grouped among the only extant subclass of Class Crinoidea. They are differentiated from the remaining extinct sub classes by lack of an anal plate and the presence of entoneural system.

The arms of all articulata are pinnulate in that they have alternating pinnules branching out along them to effectively increase the surface area for feeding. Solnhofen Lagerstatte had the very special environment required to preserve the delicate floating crinoids.

Saccocoma remains are the most common macroscopic fossils in the Solnhofen limestone.
