Ammonite Pair (AMN1) - Split & Polished - Madagascar - 3 Inches from DINOSAURS ROCK
Beautiful Split & Polished Ammonite
Measures 3 x 2 x 1/2 Inches
Weighs 4.3 oz
Great gift or display piece.
This one-of-a-kind fossil ammonite comes as a matching pair, sliced into two perfect halves and polished, each a fascinating specimen. It makes for a wonderful fossil gift or even an earth science teacher or paleontologist resource.
Ammonites are the ancient equivalent of the modern-day chambered Nautilus. These sea-faring squids built a chambered shell in which they would pump air into the empty chambers and float at different levels of the ocean in search of food. This unique ability to float at different depths of the ocean is what inspired Jules Vern (the famous science fiction writer) to call the first submarine the Nautilus.
Ammonites lived approximately 400 million years ago. The extinct ammonite that descended from Nautiloids is an example of the remarkable symmetry often found in nature. Ammonites were Cephalopods sharing a common ancestor with the squid and octopus that appeared in the Devonian and disappeared with the dinosaurs at the end of the Cretaceous period.
The specimen pictured is the one you will receive. No two ammonites are alike!

Genuine petrified wood fossil specimen. Polished to show detail. Petrified wood (from the Greek root petro meaning "rock" or "stone"; literally "wood turned into stone") is the name given to a special type of fossilized remains of terrestrial vegetation. It is the result of a tree having turned completely into stone by the process of permineralization. All the organic materials have been replaced with minerals (mostly a silicate, such as quartz), while retaining the original structure of the wood. Stand not included. From Indonesia. Approx 6" wide - photo is representative of the one you will receive.
