What is an Orthocera?
Orthoceras were the earliest recognizable animals and were able to swim
and crawl. Orthoceras ranged in size from a few inches to over six feet long.
When they died, their shells fell to the ocean floor and over the years minerals
replaced the animals' organic matter turning them to stone. |
