2" Wide Kosmoceras Ammonite - England

This is a 2" wide Kosmoceras (Guliemiceras) jasoni ammonite from Ashton Keynes, Gloucestershire, England. The ammonite is beautifully prepared in the matrix in which it was found. They are often found in clusters which can lead to parts of other ammonites or gastropods to become part of the matrix. This makes each specimen unique and truly one of a kind.

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.
