9.5" Triassic Ammonite (Discoceratites) Fossil - Germany
This is a large, 9.5" wide Discoceratites ammonite from Bararia. It's a very unusual Triassic ammonite and the only one of this species I've had available. It displays a very interesting and pronounced suture pattern. There is some restoration along the buttom, left edge of the ammonite. 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. Ammonites appeared in the fossil record about 240 million years ago and they barely survived several major extinction events. The last lineages disappeared 65 million years ago at the end of the Cretaceous.
