Description
 
One of the first cephalopods with an elongate, chambered shell was the orthoceras. Paleontologists estimate the beginning of their existence at about 505-523 million years ago. The primitive, elongate shell of the orthoceras was not as manageable or functional as later developed, coiled shells of cephelapods and gastropods. This is undoubtedly one of the main reasons the orthoceras soon became extinct.

Cephelopods are a class of mollusks best known for their many arms and tentacles. The elongate, partitioned shell of the orthoceras served mainly as protection and support. As the orthoceras grew, it formed more partitions in its shell.

Origin: Northern Africa. Fossil measures 2-3" (sometimes longer) on its longest side. Price is per orthocras fossil.
