ABSTRACT
The Permian marine and continental sedimentary sequences in south central Mxico and the biota contained in them are analyzed in this paper. The fossil flora and fauna are contained in Permian strata that correspond to the Guacamaya Formation in the states of Hidalgo and Veracruz; to the Patlanoaya, Los Hornos, Cuxtepeque, and Matzitzi Formations in the state of Puebla; to the Olinal
Formation in the state of Guerrero; to the Ihualtepec, Ixtaltepec, and Yodode
e Formations in the state of Oaxaca; and to the Paso Hondo Formation in the state of Chiapas.
The microfaunistic association of Olinal fusulinids can be correlated with the Guadalupe Mountains and the La Mar Formation of Texas in the U.S.A., and with the Difunta Formation of Coahuila and strata of the states of Sonora, Guerrero, and Oaxaca in Mexico. Fusulinids from the Olinal, Ihualtepec, and Yododee Formations suggest that during the Late Permian (Wordian-Capitanian), these organisms were part of the same paleogeographic province that comprised Texas, Arizona, New Mexico, and California in the United States, and northern Sonora, Chihuahua, Coahuila, extending into central Mexico.
