Abstract
The distribution and general lithology of the Late Paleozoic limestone in southern Chiapas are discussed. There are also notes on all of its known fauna, and a detailed discussion of 2 spp. of ammonoids belonging in the genera Perrinites and Peritrochia. The limestone is Middle Permian in age and that at least the ammonoid-bearing portions of it belong in the Leonard series.This publication has 2 references indexed in Scilit:
