ORTHOCERAS FOSSILS
Orthoceras
("straight horn") is a genus of extinct cephalopod
Orthoceras are dated to the lower Ordovician to Triassic ages (500 to 190
million years ago).
They are ancestors to the modern day squid.
The Orthoceras ranged in size from a few inches in length to over six feet.
They could swim as well as crawl on the ocean floor. By filling the chambers
in their shells with air they could float through the seas propelling themselves
by squirting jets of water. As they died their shells accumulated upon the
ocean floor, then covered by sediments they transformed into stone over the
ages. Our Orthoceras specimens are from the Atlas Mountains in Morocco, and
are dated back to the Silurian Age 400 + million years ago.
