9.3" Tall, Composite Ammonite Fossil Display - 110 Million Years Old
This is a very aesthetic cluster of 110 million year old ammonite and gastropod fossils from the Mahajanga Province of Madagascar. The entire piece measures 9.3" tall, 8.4" wide and weighs about 14 lbs. Several of the ammonite fossils appear to have been composited onto the rock, but it's a beautiful display piece. The largest ammonite on the piece is 4.4" across. Many of the ammonites display the distinctive suture patterns of the inner shell, while others show the iridescent outer shell.
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.
