This is a very displayable piece from Dorset, England featuring a large, 12" wide Euhoploceras marginatum ammonite and a cluster of naturally associated Belemnites (Passaloteuthis sp). The entire block of limestone measures 18.2" high, is nicely prepared and displays well standing up on a flat surface. The belemnites, the largest of which is 7" long have been polished.

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.

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.
