7.5" Pyrite Replaced Fossil Ammonite (Dactylioceras) Cluster - England

This is a fantastic, 7.5" wide cluster of pyrite replaced Dactylioceras ammonites from the Scunthorpe, England. There about 18 ammonite fossils, ranging from .5 to 2.2" wide which have been painstakingly prepared from the hard limestone. They have undergone pyrite replacement which is evident by the golden color of many of them, as well as the weight of the piece.

This piece comes out of the collection of the late Jeff Mulroy, a renown collector and preparitor of Yorkshire fossils.

Comes with a display stand.

Ammonites were predatory mollusks that resembled a squid with a shell. These cephalopods had eyes, tentacles, and spiral shells. They are more closely related to a living octopus, though the shells resemble that of a nautilus. True ammonites appeared in the fossil record about 240 million years ago. The last lineages disappeared 65 million years ago at the end of the Cretaceous.
