FootnotesThe mammoth lineage branched from the Asian elephant around 6 million years ago, and later on, the Woolly Mammoth, Mammuthus primigenius, evolved in eastern Siberia. Woolly mammoths, being slightly smaller than living African elephants, were foragers and ate grass, as well as small, nutritious flowering plants that flourished in the environment where they lived. They may also have used their curved tusks to dig through snow and eat plants that other foragers were unable to reach.

The striking iridescence of these ammonites from Alberta, Canada, termed 'ammolite', was given the status of a gemstone by CIBJO in 1981. An iridescent opal-like play of colour is shown in fine specimens, and is caused by the microstructure of aragonite, the same mineral contained in pearls and nacre. The thicker the structural layers, the more reds and greens are produced; the thinner the layers, the more blues and violets predominate. The ammonites are a group of molluscs that lived in the seas from the mid-Devonian (approximately 400 million years ago) to the end of the Cretaceous (65 million years ago). The sequence of events that famously killed off the dinosaurs also drove the ammonites to extinction.
