“…The Bauru Group is the Upper Cretaceous Sequence of the Bauru Basin, the largest sedimentary basin of that age in South America and one of the best studied continental basins in Brazil, well documented throughout 500 outcrops and thousands of well logs (Batezelli et al, 2019). Extending over 330,000 km 2 in an elongated NNE area in south-eastern and central Brazil, the Bauru Basin is best documented in the northwestern Paraná, western São Paulo and Minas Gerais states, with vast areas still to be systematically explored in southwestern Goiás, southeastern Mato Grosso and eastern Mato Grosso do Sul states (Barcelos & Suguio, 1987;Batezelli et al, 2007;Basilici & Dal'Bó, 2010;Menegazzo et al, 2016, Candeiro et al, 2020.…”

The Late Cretaceous continental deposits of the Bauru Group of Brazil have a rich vertebrate fossil fauna, but studies on the fossil fishes from the unit are scarce. This paper describes new occurrences of the Vidalamiinae subfamily of the bony fish group Amiidae (Halecomorphi: Amiiformes). The new occurrences are comprised by three isolated vertebral centra and three isolated teeth from the Marília and Adamantina formations, which were collected in Uberaba and Prata municipalities. The fossils described here not only expand the record of Vidalamiinae for the Bauru Group, but also clarify that the assignment of isolated teeth to this group may now be done with more certainty, which was not the case in many previous studies. Additionally, we also refer the described specimens tentatively to the Vidalamiini, which is the first assignment to this group and to the tribe level for any fish material from the Bauru Group. This study also offers an overview on the paleobiogeography of the Amiidae during the Late Cretaceous and an updated compilation of vidalamiine records during the Cretaceous, with a special focus on the freshwater records of this originally saltwater group. Finally, we also discuss the distribution of the tribes Vidalamiini and Calamopleurini during the Late Cretaceous, and the possibility that the North American and South American vidalamiines may have dispersed between the continents through a land connection. Keywords: Amiiformes, Amiidae, Vidalamiinae, Bauru Group, Late Cretaceous, biogeography. RESUMO – Os depósitos continentais do Cretáceo Superior do Grupo Bauru do Brasil possuem uma rica fauna fóssil de vertebrados, mas os estudos sobre os peixes fósseis da unidade são escassos. Este artigo descreve novas ocorrências da subfamília Vidalamiinae do grupo de peixes ósseos Amiidae (Halecomorphi: Amiiformes). As novas ocorrências são compostas por três centros vertebrais e três dentes isolados das formações Marília e Adamantina, que foram coletados nos municípios de Uberaba e Prata. Os fósseis aqui descritos não apenas ampliam o registro de Vidalamiinae para o Grupo Bauru, mas também esclarecem que a atribuição de dentes isolados a este grupo pode agora ser feita com mais certeza, o que não era o caso em muitos estudos anteriores. Adicionalmente, também remetemos os espécimes descritos provisoriamente aos Vidalamiini, que é a primeira atribuição a este grupo e ao nível de tribo para qualquer registro de peixes do Grupo Bauru. Este estudo também oferece uma visão geral da paleobiogeografia dos Amiidae durante o Cretáceo Superior e uma compilação atualizada dos registros de vidalamiine durante o Cretáceo, com foco especial nos registros de água doce desse grupo originalmente de água salgada. Por fim, também discutimos a distribuição das tribos Vidalamiini e Calamopleurini durante o Cretáceo Superior e a possibilidade de que os vidalamiines norte-americanos e sul-americanos tenham se dispersado entre os continentes por meio de uma conexão terrestre. Palavras-chave: Amiiformes, Amiidae, Vidalamiinae, Grupo Bauru, Cretáceo Superior, biogeografia.

“…In Brazil, records of dinosaurs are widely known from the Bauru Group (Late Cretaceous), mostly from the Triângulo Mineiro region, in the state of Minas Gerais (e.g., Kellner & Campos, 2000;Campos et al, 2005;Faria et al, 2015;Bandeira et al, 2018;González-Riga et al, 2019) and from western São Paulo state (Santucci & Arruda-Campos, 2011;Bandeira et al, 2016;Delcourt & Iori, 2018). More recently, some new findings are known from the other poorly explored regions, such as the outcrops in Goiás (Candeiro et al, 2018(Candeiro et al, , 2020. However, due to the historical and highly fossiliferous nature of the units, especially the Triângulo Mineiro area, several contributions discuss the geological and paleontological re-search performed by geoscientists in this region (e.g., Candeiro, 2007;Peyerl et al, 2015;Candeiro & Figueiroa, 2017).…”

Titanosaurs are one of the most common dinosaurs found in Cretaceous outcrops, especially in Brazil. In this article we describe a proximal portion of an ulna (Paleo-UFG/V-0039) which was found isolated Paleo-UFG/V-0039 comes from a sandstone outcrop, with fine to medium granulation, of the Marília Formation (Bauru Group) that appears irregularly in the municipality of Gurinhatã, state of Minas Gerais, Brazil. The occurrence described here is the first dinosaur osteological remains documented in this municipality. Although incomplete, Paleo-UFG/V-0039 could be identified as an indeterminate lithostrotian titanosaur whose morphology is similar to some appendicular elements of European species than South American ones. However, the incompleteness of the specimen has difficult complex interpretations. Finally, Paleo-UFG/V-0039 highlights the importance of the Gurinhatã outcrops and other sites in this region for future discoveries.
