This Ammonite Fossil greeting card has been lovingly designed from my watercolour hand-painted originals. This card is perfect for the nature lover in your life, featuring a detailed illustration of an ancient, fossilised sea creature. The intricate design of the ammonite is sure to bring a sense of awe and wonder to the recipient. This card is a perfect way to show someone you care. Ammonites were shelled cephalopods that died out about 66 million years ago. Fossils of them are found all around the world, sometimes in very large concentrations.
