Fossil This picture of a fossil is a continuous shape, going around leading it to get bigger in size. Having a bumpy outer shell with no smooth edges, the pattern on the shell is natural and jagged creating a broken texture.
Ammonite fossil: These creatures lived between 240 - 65 million years ago, when they became extinct along with the dinosaurs. 'ammonite' (usually lower-case) originates from the Greek Ram-horned god called Ammon. Ammonites belong to a group of predators known as cephalopods, which includes their living relatives the octopus, squid, cuttlefish and nautilus. Ammonites moved by jet propulsion, expelling water through a funnel-like opening to propel themselves in the opposite direction.
