“…Therefore, given the lack of any published or observable distinctive characters, Lepidosiren megalos is herein considered a junior synonym of Lepidosiren paradoxa , as suggested by Lundberg et al . (2010), an opinion never followed in subsequent literature (Agnolin 2010; López-Fernández & Albert 2011; Alves et al . 2013).…”

“…A number of studies have improved our understanding of the geology and paleontology of the Cocinetas sedimentary basin in the Guajira Peninsula of northern Colombia (Moreno et al 2015). Several vertebrate groups are represented in these sediments, both marine and continental (Aguilera et al 2013b(Aguilera et al , 2017Forasiepi et al 2014;Cadena & Jaramillo 2015a,b;Amson et al 2016;Moreno-Bernal et al 2016;Suarez et al 2016;Carrillo-Briceño et al 2019); in contrast, freshwater fishes remains largely unreported in these assemblages (but see Aguilera et al 2013a).…”

Freshwater fossil fish faunas have been long used to infer past drainage connections, as they are bounded by physical freshwater barriers. Here we study a middle Miocene (15.0-15.5 Ma) fossil fauna (Makaraipao) from the Castilletes Formation in northern Colombia, nowadays west of the Andes. We record the presence of lungfishes (Lepidosiren), pacus (Mylossoma and Piaractus), armored catfishes (Callichthyidae), and red-tail catfishes (Phractocephalus). Extant members of all those groups (except the Callichthyidae, due to lack of taxonomic resolution) are found in Amazonian faunas east of the Andes and are absent from faunas west of the Andes, indicating that the riverine systems of the Guajira Peninsula were connected to Amazonia during the middle Miocene. The similarity of La Venta (west of the Andes) and Rio Acre (east of the Andes) fish faunas during the late Miocene further indicates that the northern Andean uplift was not a complete barrier at least until ~ 11 Myr ago. However, there is a continental-wide structuring of the Miocene fish faunas that is also found in the extant faunas, suggesting that other factors, in addition to the uplift of the Andes, have shaped the biogeographic evolution of South American fish faunas.

The similarity of La Venta (west of the Andes) and Rio Acre (east of the Andes) fish faunas during the late Miocene further indicates that the northern Andean uplift was not a complete barrier at least until c. 11 Ma. However, there is a continental‐wide structuring of the Miocene fish faunas that is also found in the extant faunas, suggesting that other factors such as ecological conditions, in addition to the uplift of the Andes, have shaped the biogeographic evolution of South American fish faunas.

“…The record of fish has been revised as well. Alves et al (2013) assigned the genus Asiatoceratodus to the specimen that was previously identified as Neoceratodus (Bertini et al, 1993), found in the Adamantina Formation. However, the authors noted that this specimen was found in a reworked clast and might not indicate the age for the Adamantina Formation.…”

The aim of this research is to understand the tectonic setting of the Bauru Basin. This basin in centraleastern South America has been classified as intracratonic, but the basin-fill geometry, the involved subsidence mechanisms and the age of the deposits are poorly understood. In this work, the ranges of the fossil taxa are analyzed and ages are proposed for the lithostratigraphic units. Isopach maps were used to reconstruct the stratigraphic intervals of the basin fill. The stratigraphy of the Bauru Basin is compared with that of the adjacent basins, and the data are integrated with the available information on South American geodynamics. The fossil record indicates that sediment accumulated from the Cenomanian to early Paleocene, beginning after the Mochica Phase of the Andean orogeny. The basin-fill geometry demonstrates migration of the depocenter through time, which occurred simultaneously with migration of the Andean Basin and immediately after the orogenic events of the Peruvian Phase. We propose that the Bauru Basin is a component of a retroarc foreland system developed during the early stages of the Andean evolution and that it was developed in the back-bulge province of this system. The Andean Basin constitutes the foredeep depozone of this foreland system (including the Potosí, Oriente, Acre and Marañon basins). In addition, the Upper Cretaceous of the Parecis and Solimões basins were likely also developed in the back-bulge province. The thickness of the Bauru accumulation indicates that other mechanisms might have overlapped the flexural subsidence in this back-bulge province.
