ResumenAunque solamente el 11.5% del área de Antioquia tiene afloramientos de rocas sedimentarias, la revisión bibliográfica y elaboración de un mapa digital de las localidades fosilíferas (27), permite concluir que esta región tiene un gran potencial paleontológico. Los datos muestran que las ocurrencias fósiles antioqueñas datan desde el período Ordovícico (~ 485.4 a ~443.8 Ma) hasta el Cuaternario (~ 2.6 Ma al Presente). Además, se encuentran macro-fósiles pertenecientes a diferentes phyla (i.e. Arthropoda, Chordata, Hemichordata, Echinodermata, Mollusca y Trachaeophyta). La paleofauna más antigua está conformada por graptolites y trilobites en metasedimentos del Paleozoico, mientras que moluscos marinos y equinodermos conforman las principales localidades fosilíferas del período Cretácico. La paleoflora (i.e. hojas fósiles y xilópalos) de la zona está asociada a la Formación Amagá (Oligoceno -Mioceno). Finalmente, fósiles de vertebrados terrestres (i.e. mastodontes y equinos) se encuentran en depósitos Cuaternarios.Palabras clave: macro-fósiles; Fanerozoico; paleontología. Review of fossiliferous localities at Antioquia department, ColombiaAbstract Even though only 11.5% of Antioquia's area has outcrops of sedimentary rocks, a review of the literature and the development of a digital map of fossil localities (27), allows us to conclude that the region has a great palaeontological potential. The data show that Antioquia's fossil occurrences date from Ordovician (~ 485.4 to ~ 443.8Ma) to Quaternary (~ 2.6Ma to the Present). Moreover, there are macro-fossils belonging to different phyla (i.e. Chordata, Echinodermata, Hemichordata, Mollusca and Trachaeophyta). The oldest paleofauna in the area, consists of graptolites and trilobites recorded in Paleozoic metasedimentary rocks, whereas marine mollusks and echinoderms compose the major fossil assemblages of the Cretaceous. The paleoflora (i.e. fossil leaves and petrified wood) in the area is associated with to the Amagá Formation (Oligocene -Miocene). Finally, fossils of terrestrial vertebrates (i.e. mastodons and horses) are recorded in Quaternary deposits.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
