Tropical freshwater teleosts from Miocene beds of eastern Patagonia, southern Argentina

Molecular Clocks Provide New Insights Into the Evolutionary History of Galeichthyine Sea Catfishes

“…Major growth of the East Antarctic Ice Sheet occurred 14.8–14.1 mya and represented a permanent cooling of the planet. Global water temperatures were highest early in the Miocene and cooled with the end of the Miocene Climate optimum (Savin et al 1985), although temperatures might have remained higher in South Africa until at least 8 mya based on oxygen isotope data (Savin et al 1985), and in Patagonia until at least 9 mya based on the presence of fossil sharks, teleosts, mammals, and mollusks (Cione et al 1996, 2005).…”

The Acre vertebrate fauna: Age, diversity, and geography

“…9(B12)). Farther southern extension may have existed, as suggested by the recent finding of continental vertebrates as far south as Península Valdés, Patagonia (Dozo et al, 2002;Cione et al, 2005). The existence of a continuous aquatic connection between the Mesopotamian and Acre regions is inferred by the presence of shared species of aquatic amniotes (cetaceans, sirenians, and crocodiles) and fishes during the Late Miocene (see Appendix B; Cione et al, 2000).…”

Bioestratigrafía basada en quistes de dinoflagelados del Neógeno en el noreste de la Patagonia, Argentina

“…La edad de los depósitos de la transgresión Entrerriense en el noreste de la Patagonia ha sido definida como Mioceno tardío basada principalmente en su contenido fosilífero (Feruglio, 1949;del Río, 2004;Palazzesi & Barreda, 2004;Cione et al, 2005;Dozo et al, 2010). Dataciones por el método 87 Sr/…”
