Polished Orthoceras Fossil Large Paleontology Specimen
 

One of the first cephalopods with an elongate, chambered shell was the orthoceras.  Paleontologists estimate the beginning of their existence at about 505 to 523 million years ago.  The primitive, elongate shell of the orthoceras was not as manageable or functional as later developed, coiled shells of cephalopods and gastropods.  This is undoubtedly one of the main reason the orthoceras soon became extinct. 
Cephalopods are a class of mollusks best known for their many arms and tentacles.  The elongate, partitioned shell of the orthoceras grew, it formed more partitions in its shell
