Red Ammonite Fossil
Ammonites are an extinct group of marine animals in the Cephalopoda class. Red ammonites display red flash, which is opalized, or iridescent. The unusual coloration of these ammonites is caused by light passing through layers of aragonite and conchiolin built up in the animal during its life cycle, then preserved through fossilization.
Each fossil is unique and the photo does not do them justice. They shine a gorgeous shade of red within the shell's structure. Each specimen measures approximately 3 - 3.5 cm.
The sizing is very slight, but the thickness and depth of red coloring varies (thus the price difference).
