2" Triassic Fossil Ammonite (Gymnotoceras) - Nevada

This is a 2" fossil ammonite (Gymnotoceras blakei) from the Prida Formation in Lovelock, Nevada.

This ammonite fossil is part of a old collection of ammonite fossils we recently acquired.

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.
