Massive, 19" Jurassic Ammonite (Kranosphinctes?) Fossil - Madagascar

Massive, Jurassic Ammonite (Kranosphinctes?) Fossil - Madagascar #175781

This is a huge, 19" wide ammonite (Kranosphinctes?) fossil from Madagascar. It is Late Jurassic in age and it was collected near Sakaraha in the Tulear Province of Madagascar. It's a beast weighing over 90 lbs. There is some repair and minor restoration, as is the case with most of the larger ammonites that are fractured by geological forces while still in the ground. The surface of the ammonite has been lightly polished.

Comes with a metal 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.
