Mayan stage

From Wikipedia, the free encyclopedia

The Mayan stage is the final Russian and Kazakhian Faunal stage of the Middle Cambrian Epoch. It occurred between 501 and 502 million years ago. The end of the [Mayan stage is marked by the earliest appearance of the agnostoid trilobite Glyptagnostus reticulatus. The Mayan stage is preceded by the Russian-Kazakhian Stage known as the Amgan. It is followed by the Russian faunal stage the Ayusokkanian and the Australian faunal stage known as the Mindyallan.
