7.5" Fossil Ammonite & Gastropod Cluster - Fresney, France

Fossil Ammonite & Gastropod Cluster - Fresney, France #265291

This is an aesthetic, 7.5" wide cluster of fossil ammonites (Perisphinctes) and gastropods (two types) from Fresney, France. These are Middle Jurassic in age or approximately 170 million years old. The preparation on this piece is wonderful and the base of the rock has been cut flat so that it displays nicely without the need for a 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.
