Cuiciloan

The Cuiciloan period is the first and oldest period of the Epilithic Era, lasting from 69 to 40 million years ago. It is the last period wherein the world's climate zones remained fixed by latitude and sea currents, and the first period in which mammals made up the predominant megafauna. As such, it is considered the beginning of the Age of Mammals.

The Cuiciloan is named specifically after the island of Cuiciloa, in the Huitca Federation. The island has rich deposits of amber, giving the period its name; said amber deposits contain abundant fossils of insects and other small animals. Other well-known formations include the Arcturus Mudstone, where the fossils of the Fislanki Death Turtle are known from.
