“…Bostryx jujuyensis (Holmberg, 1900) as Bulimulus aff. jujuyensis was mentioned from early Late Miocene of Catamarca (Miquel, 1995;Salvador et al, 2018).The specimens here reported constitute the first record for the family for the Cretaceous of Patagonia.…”

“…Genus Physa has been reported from different Upper Cretaceous localities of North America (White, 1877;Taylor, 2003;Russell, 1935) and South America (Cabrera et al, 2018;Mezzalira, 1974;Ghilardi et al, 2011). For Patagonia, the species Physa doeringi Doello Jurado, 1927, and Physa wichmanni Parodiz, 1961, have been described for the Maastrichtian-Danian Jagüel Formation (Río Negro province; Salvador et al, 2018). Thus, discovery of specimens of Physa in duced radial diameter.…”

“…Until relatively recently, the records of Mesozoic land snails were almost restricted to North America and Europe (Solem, 1979). In contrast, the Cretaceous records of conti-nental gastropods from South America were barely represented by some specimens of the families Pleuroceridae (Early Cretaceous), Physidae (Early Cretaceous), Bulimulidae (Late Cretaceous) and "Endodontidae" (Late Cretaceous) (Salvador et al, 2018) (see Table 1). Pleuroceridae and Bulimulidae were unknown from Mesozoic beds, and their respective fossil records were restricted to the Cenozoic of Patagonia (Parodiz, 1969).…”

“…In South America, the subulinine genus Neobeliscus Pilsbry, 1896 is recorded from the Miocene Pebas Formation (Brazil). Extant subulinines inhabit South America (Simone & Mezzalira, 1994;Salvador et al, 2018), being absent from Patagonia. The specimens collected from the Chorrillo Formation may represent the first records for the subfamily for the Cretaceous worldwide.…”

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.
