Geniune Whole Madagascar Polished Sutured Ammonite Specimen 4"x3" AM-14

Description

This Ammonite is a whole fossil, unsliced and is a stunning showpiece for collectors.  It has been polished on the outside so you can see each sutured pattern ( the leafy pattern) that encompasses this entire fossil specimen.  This ammonite fossil is from Madagascar.
Approximately 4" length x 1.5"  width x 3" height.
There were many different types of ammonites dating between the Jurassic and Devonian periods (65 and 419 million years ago).  The more complex the ammonite fossils, the more recently they were created in those periods.  Ammonites died away at the same time as the dinosaurs.
Ammonites (subclass Ammonoidea) can be distinguished by their septa, the dividing walls that separate the chambers and are a group of extinct marine mollusc animals in the subclass Ammonoidea of the class Cephalopada.  These mollusks are more closely related to living coleoids such as octopuses, squid, and cuttlefish.
