Due to the continued cooling of the planet and its oceans the Earth entered a phase called the “Cryogenian Ice Age” this was soon followed by the “Cambrian Expansion” which saw the development of the earliest fish-like creatures alongside many early arthtopods and mollusks. This was then followed by the “Andean-Saharan Glaciation” yet another phase of the Earths Ice ages.
