White Ammonites

Regular price $8.00 Sale

Ammonoidea, the sub-order containing Goniatites and Ammonites, speaks to a species of cephalopod that lived in the Devonian period (419 million years ago) to the Cretaceous period.  The species died out during the Cretaceous-Paleogene extinction event some 65 million years ago.  Each sub-species can be identified by their suture pattern and are classified as Goniatitic (commonly called Goniatites), Ceratitic, or Ammonitic (Ammonites).  

These white ammonites are called Asteroceras ammonites.  They lived during the Triassic and Jurassic periods (205 to 189 million years ago).  

The perfect starter fossil for the new collector, these prehistoric looking ammonites have a ribbed pattern with a chalky-white exterior.  Each specimen is unique with colors ranging from creamy-white to sandy-tan.  These specimens are from Madagascar.  

The specimens measure 2” to 2-1/2” in diameter.  Each ammonite will show chipped, or cracked areas - none are perfect which makes them ideal stater-pieces.  While most are intact, some may contain evidence of restoration work. As you can imagine, the process of extracting these specimens from the earth can result in damage and cracking.  The miners restored the fossil by bonding the pieces back together. 

Each specimen is unique and the photographs are of representative pieces, intended to show the variations among specimens.  We will select a specimen for you. Contact us before placing your order if you would like to select your specific piece. We will send you a photograph of available specimens so you can select your preferred piece.
