JIMENEZ-LOPEZ, José Carlos; SOUR-TOVAR, Francisco; BUITRON-SANCHEZ, Blanca Estela  e  PALAFOX-REYES, Juan José. Late Paleozic brachiopods of the Sierra Agua Verde, Sonora; palaeoecological and palaeogeographic implications. Rev. Mex. Biodiv. [online]. 2018, vol.89, n.3, pp.637-650. ISSN 2007-8706.  https://doi.org/10.22201/ib.20078706e.2018.3.2143.

The brachiopods Plicatifera sp., Kozlowskia capaci, Linoproductus sp. cf. L. eastoni, Composita sp cf. C. sp. cf. subtilita, Anthracospirifer occiduus (Sadlick, 1960), Hustedia mormoni (Marcou, 1858), and Reticulariina sp., are described for the Late Paleozoic of Sierra Agua Verde, Sonora from the La Joya formation, which is made of limestone, sandy limestone, and chertly limestone, and irregular sandstone and siltstone interbeded. The associated biota includes algae, foraminifers, sponges, corals, bryozoan, gastropods, and crinoids that suggest environmental conditions of carbonate platforms with normal salinity and fluctuating levels of energy and nutrient availability. The distribution analysis of the brachiopods allows to establish the palaeogeographic relationships with fauna of Mexico (Oaxaca, Hidalgo), USA (Idaho, Wyoming, Nebraska, Nevada, Ohio, Kansas, Utah, Missouri, Pennsylvania, Arizona, New Mexico, and Texas), Canada, South America (Bolivia, Peru), Europe (Ireland, Belgium), and Asia (Russia, China, Japan, Indonesia).
