10.5" Agatized Ammonite (Promicroceras) Mass Mortality - Lyme Regis

 
 
This is an impressive, 10.5" wide, mass-mortality plate of Promicroceras ammonites from Lyme Regis, England. There are well over one hundred ammonites on this plate which have been replaced with agate. Many, many hours went into preparing this piece to exposed all of the ammonites in the hard limestone. A truly spectacular piece.

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.
