Resumen


Resumen

Se describe por primera vez para México el trilobite agnóstido Euagnostus interstrictus (White), recolectado en capas del Cámbrico
de la Formación El Gavilán (Miaolingiano, Wuliuano) que se localiza en el cerro El Sahuaral, parte central del estado de Sonora. En la
localidad aflora una secuencia sedimentaria del Paleozoico inferior representada por las formaciones Proveedora, Buelna, Cerro Prieto
y El Gavilán, con una litología predominante de cuarzoarenita, caliza y lutita. Esta secuencia está caracterizada por una abundante y
diversa biota fósil, la cual consiste en icnofósiles, algas oncolíticas, esponjas, hiolítidos, braquiópodos y trilobites. Las rocas cámbricas

del área de Sonora central se depositaron como parte de una potente secuencia de sedimentos del margen occidental del cratón de Lau-
rentia en un ambiente de plataforma exterior. Se confirma la distribución cosmopolita de Euagnostus interstrictus, ya que se encuentra

ampliamente distribuida en localidades como el norte de Australia (Territorio del Norte y Queensland), Europa (Dinamarca), Estados
Unidos de América (Utah y Nevada) y México (Sonora).

 

Abstract

We describe, for the first time in Mexico, the agnostid trilobite Euagnostus interstrictus (White), collected from Cambrian strata of
the El Gavilán Formation (Miaolingian, Wuliuan) which is located in the El Sahuaral hill, on the central part of the state of Sonora. A
lower Paleozoic sedimentary sequence is exposed in the study site, represented by the Proveedora, Buelna, Cerro Prieto, and El Gavilán
formations, with a predominant lithology of quartz-arenite, limestone and shale. This sequence is characterized by an abundant and
diverse fossil biota, consisting of ichnofossils, oncolytic algae, sponges, hyolithids, brachiopods, and trilobites. The Cambrian rocks
from the central Sonora area were deposited as part of a thick sedimentary sequence from the western margin of the Laurentia craton
in an outer shelf environment. The cosmopolitan distribution of Euagnostus interstrictus is confirmed, as it is widely distributed in
locations such as northern Australia (Northern Territory and Queensland), Europe (Denmark), United States of America (Utah and
Nevada) and Mexico (Sonora).
