Permian Period in geologic time The Permian Period and its subdivisions.

The Guadalupian Epoch is a subdivision of the American Permian Period, specifically the Middle Permian (Guadalupian) Series. This geological time interval spans from 265.1 million to 259.9 million years ago. It is named after the Guadalupe Mountains in Texas and New Mexico.12

Key characteristics of this epoch include significant fluctuations in sea level, which are often linked to climate changes and glaciation. The Guadalupian Epoch is marked by a major lowstand in sea level near its beginning and further fluctuations throughout its duration. Fossils found from this period include conodonts like Jinogondolella postserrata, fusulinids such as Yabeina and Polydiexodina, and ammonoids like Timorites and Strigogoniatites.31
