1.5" Jurassic Fossil Ammonite (Leioceras) - Dorset, England
This is a 1.5" wide ammonite fossil of the species Leioceras opalinum. The ammonite is Middle Jurassic in age and comes from the Middle Jurassic (Bajocian Stage) deposits of Dorset, England.
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.
