Orthoceras ("straight horn") are the ancestors of the modern day squid. 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 accummulated on the ocean floor, then covered by sediments (mud) they transformed into stone over the ages. Specimens are from the Atlas Mountain Range in Morocco, dated to the Devonian Age, about 390 million years ago.

This orthoceras in matrix pictured at left has been sold, but we have others very similar to it.

Ammonites were predatory, squid-like creatures that lived in coil-shaped shells. They constantly added to their shell as they grew but only lived in the outer chamber.

Ammonites are shaped like a ram's horn. They were named after the Egyptian God Ammon who is depicted as a man with ram's horns. The fossil was considered Ammon's stone, thus the name Ammonite.

Though they are now extinct, ammonites appeared more than 400 millions years ago and lived till 65 million years ago. They became extinct at the same time as Dinosaurs.

Ammonites have been found in the Sahara Desert and in Alberta, which were once ancient seabeds.
