Spiral Pattern in Pine Cone   Pine cones are a classic example of the logarithmic or equiangular spiral in nature. This is from a Short-leaf pine. These spirals form from processes where there is turning at a constant angle but accelerating growth. This describes the growth of many structures in the plant kingdom.   © Kevin Kopchynski

Ammonites are perhaps the most widely known fossil, possessing the typically ribbed spiral-form shell as pictured above. These creatures lived in the seas between 240 - 65 million years ago, when they became extinct along with the dinosaurs.

These curls are another example of spirals formed in nature. Before these blades fully mature they are found in a spiral form.
