Prehistoric Fossil. Extinct Class - Orthoceras - Gray 9" with Display Stand. The Orthoceras was a very primitive member of the Phylum Cephalopoda and is similar to the Ammonite, with a straight shell. Approximately 400 Million Years Old, Orthoceras are the ancestral cousin of the modern Squid or Octopus. The word Orthoceras means "Straight Horn" and refers to its shape and have chambers separated by walls called Septa. The tube that runs down the center of the fossil is called a Siphuncle and was used to carry gas into the chambers to control the buoyancy of the shell. The Orthoceras from Morocco occur as a white fossil in a dark gray and black marble matrix which results in a fossil with very good contrast. Price includes: Metal Display Stand. Shipping weight 4 lbs. Item photographed is representative specimen.
