Guadalupian Series
Quick Summary
The Guadalupian Series is a subdivision of the Permian Period, specifically the Middle Permian epoch. It is named after the Guadalupe Mountains in the United States. This series encompasses three ages: the Roadian (272.3 to 268.8 million years ago), Wordian (268.8 to 265.1 million years ago), and Capitanian (265.1 to 259.9 million years ago).1
The base of the Roadian Stage is marked by the appearance of the conodont Jinogondolella nankingensis. The Wordian Stage begins with the appearance of Jinogondolella aserrata, and the Capitanian Stage is defined by the first occurrence of Jinogondolella postserrata. These conodonts, along with other fossils like ammonoids and fusulinids, help geologists correlate rock layers across different regions. Establishing precise time equivalence for Permian strata has been challenging due to endemic marine faunas.2341
