Class Trilobita (including agnostoids) from Argentine Precordillera

Abstract

This data paper inventories the records of 1763 trilobites (including agnostoids) from the MiddleCambrian inner and outer platform of the Argentine Precordillera (San Juan and Mendoza provinces).They were collected by Dr. Osvaldo Bordonaro and his colleagues between 1994 and 2013 and studiedwithin the framework of scientific research. The specimens are stored in the Instituto Argentino deNivología, Glaciología y Ciencias Ambientales (IANIGLA, CCT-CONICET Mendoza, Argentina), anofficial paleontological repository of Mendoza Province and are part of its PaleoinvertebratesCollection. The study of these trilobites contributed to the taxonomy of the group and allowed theestablishment of important paleobiogeographic connections between Cuyania and Laurentia during the Cambrian. From a preliminary Microsoft Excel format, the dataset is now included in the GlobalBiodiversity Information Facility (GBIF, https://www.gbif.org), under the publisher CCT-CONICETMendoza (Argentina), making it available to the public.
