1.3" Promicroceras Ammonite - Lyme Regis

This is a very beautiful Promicroceras planicosta ammonite fossil from the Lyme Regis region of England which has been replaced with a golden calcite. It's almost translucent and has been nicely prepared so that it displays nicely in a sculpted piece of limestone.

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.
