8.2" Stephanoceras Ammonite - Dorset, England

This is a nicely prepared and uncommon Stephanoceras ammonite from the Dorset Coast region of England. This one is quite large at 8.2" wide and makes a stunning display. The base of the rock has been cut flat so that it stands up nicely without the need for a display stand.. It's Middle Jurassic, Bajocian Stage in age or approximately 160 million years old.

Ammonites were predatory cephalopod mollusks that resembled squids with spiral shells. They are more closely related to living octopuses, though their shells resemble that of nautilus species. True ammonites appeared in the fossil record about 240 million years ago during the Triassic Period. The last lineages disappeared 65 million years ago at the end of the Cretaceous.
