Orthoceras Fossil - imported from Morocco.

This extinct fossil from the Devonian Age lived in a shallow sea approximately 350 million years ago.  This particular piece is a combination of several fossilized orthoceras shells.  The orthoceras is distinguished by a straight, rather than curved shell, with a center siphuncle.  This polished fossil is a relative of today's chamberized nautilus.

These straight shelled nautiloids ranged in size from less than a centimeter to more than 14 feet long!  This fossil measures 13" x 8".
