7.8" Fossil (Androgynoceras) Ammonite with Bite Mark - England

This is a 9" wide plate of ammonites that was collected from the Lower Jurassic, Lower Lias - Daveoi Zone of Dorset, England. The ammonites have been exposed from the rock they were found in. The largest ammonite (Androgynoceras lataecosta) has a bite mark taken out of it from a predator. This specimen comes with an acrylic/metal (gibson) display stand.

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.
