“…Basal anurans of the clade Pipoidea have been recorded from the Early Cretaceous of Brazil (Carvalho et al, 2019) and from mid-to Late Cretaceous localities of Brazil and Argentina (see Báez, 2000). The record of neobatrachians is also restrictive, being currently represented by nearly complete specimens from the Early and Late Cretaceous of Brazil (e.g., Báez & Perí, 1989;Báez et al, , 2012, and disarticulated specimens from Campanian-Maastrichtian localities in Chubut and Río Negro provinces of Argentina (i.e., Báez, 1987;Martinelli & Forasiepi, 2004;Muzzopappa & Baez, 2009;Agnolin, 2012).…”

The first fossil remains of vertebrates, invertebrates, plants and palynomorphs of the Chorrillo Formation (Austral Basin), about 30km to the SW of the town of El Calafate (Province of Santa Cruz), are described. Fossils include the elasmarian (basal Iguanodontia) Isasicursor santacrucensis gen. et sp. nov., the large titanosaur Nullotitan glaciaris gen. et sp. nov., both large and small Megaraptoridae indet., and fragments of sauropod and theropod eggshells. The list of vertebrates is also composed by the Neognathae Kookne yeutensis gen. et sp. nov., two isolated caudal vertebrae of Mammalia indet., and isolated teeth of a large mosasaur. Remains of fishes, anurans, turtles, and snakes are represented by fragmentary material of low taxonomical value, with the exception of remains belonging to Calyptocephalellidae. On the other hand, a remarkable diversity of terrestrial and freshwater gastropods has been documented, as well as fossil woods and palinological assemblages. The Chorrillo Formation continues south, in the Las Chinas River valley, southern Chile, where it is called Dorotea Formation. Both units share in their lower two thirds abundant materials of titanosaurs, whose remains cease to appear in the upper third, registering only elasmarians (Chorrillo Formation) and hadrosaurs (Dorotea Formation). Above both units there are levels with remains of invertebrates and marine reptiles. It is striking that the dinosaurs of the lower two thirds of the Chorrillo and Dorotea formations are represented by large basal titanosaurs and Megaraptoridae coelurosaurs, being the Saltasaurinae and Aeolosaurinae sauropods and Abelisauridae theropods totally absent. In contrast, these taxa are dominant components in sedimentary units of central and northern Patagonia (e.g., Allen, Los Alamitos, La Colonia formations). Such differences could reflect, in part, a greater antiquity (i.e., late Campanian-early Maastrichtian) for the Chorrillo fossils, or, more probably, different environmental conditions. Thus, knowledge of the biota of the southern tip of Patagonia is expanded, particularly those temporarily close to the K-Pg boundary.

“…Most of the findings comes from Argentina, and it is a reflex of the relatively prolific fossil record and noteworthy amount of researchers interested in anurans there (see Cione and Báez, 2007). In Brazil, studies on fossil anurans have been sporadic and mostly related to Cretaceous specimens of the Araripe and Bauru basins (Báez and Peri, 1989;Leal and Brito, 2006;Báez et al, 2009Báez et al, , 2012.…”

We report the first occurrence of anurans in the Quaternary fossil record of Rio Grande do Norte State. The specimen UERN PV-50 was assigned to the bufonid Rhinella jimi. This finding extends the geographic distribution of this species in the northeastern Brazil during the Late Pleistocene-early Holocene. In paleoenvironmental terms, the occurrence of R. jimi in Riacho Verde paleontological site suggests an arid climate with marked seasonality in that area during the Late Pleistocene-early Holocene and that the paleobiodiversity in that region was higher than the observed in the fossil record. Furthermore, the tanks seem to have been areas of aggregating anurans during raining periods. Finally, based on sedimentological and biostratinomic data, we interpret that Riacho Verde paleontological site preserved a peripheral assemblage.

“…Adicionalmente, fósseis de diversos grupos foram encontrados em sedimentos da Formação Marília, no Triângulo Mineiro. Dentre eles encontram-se os anfíbios Baurubatrachus pricei (Báez and Peri 1989) e Uberabatrachus carvalhoi (Báez et al 2012), o iguanídeo Pristiguana brasiliensis (Estes and Price 1973), a tartaruga Cambaremys langertoni (França and Langer 2005), dinossauros terópodes Abelisauridae e Carcharodontosauridae e os saurópodes Baurutitan britoi, Trigonosaurus pricei e Uberabatitan ribeiroi (Campos et al 2005;Candeiro 2005a;Kellner et al 2005;. Desta forma, é provável que os coprólitos encontrados pertençam a diferentes grupos de vertebrados, justificando a elevada abundância e variação morfométrica.…”

“…Essas localidades já revelaram diversas espécies de microfósseis e macrofósseis e apresentam uma das mais ricas faunas de vertebrados e invertebrados do Cretáceo brasileiro . O extenso registro fóssil inclui algas carófitas e invertebrados (Mezzalira 1974;Campanha et al 1993;Magalhães-Ribeiro and Ribeiro 1999;Senra and Silva-e-Silva 1999;, peixes (Gayet and Brito 1989;Bertini et al 1993;Martinelli et al 2013), anfíbios (Báez and Peri 1989;Báez et al 2012), lagartos (Estes and Price 1973), quelônios (França and Langer 2005;Gaffney et al 2011), crocodilomorfos Kellner et al 2011) dinossauros Campos et al 2005;Kellner et al 2005;Novas et al 2005Novas et al , 2008Candeiro et al 2006;Martinelli et al 2011Martinelli et al , 2015) e aves (Candeiro et al 2012).
