14" Fossil Belemnite and Ammonite Plate - Germany

This is a 14" wide shale plate that contains a fossil belemnite (Acrocoelites sp.?) rostrum and several ammonites (mostly Dactylioceras sp.) from the Posidonia Shale of Holzmaden, Germany. The rostrum of this belemnite has been polished and is still partially inflated. The pro-ostracum of the belemnite preserved nicely and has been coated in a sealant to bring out the detail. The pro-ostracum was an additional support feature for the soft body portions of belemnites and is rarely found preserved. The rostrum of this belemnite measures 3.5" long.

Comes with an acrylic/metal (gibson) display stand.

Belemnites are probably the most well known extinct cephalopod after the ammonites. They lived during the Jurassic and Cretaceous periods and are fairly common fossils found throughout the world. They had a hard, internal, cone shaped structure that is often preserved as a fossil though it is not technically a shell. They had 10 arms but unlike modern squid these arms had small hooks instead of suckers.

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.
