Fusulinid.
The Guadalupian series includes two zones based on a sharp change of fusulinid genera, from Parafusulina to Polydiexodina. There are also some ammonoid zones and many sponges and algae. The Ochoa series has very few fossils, probably because conditions grew much less favorable for life during the last of the Permian, when many marine ...
