Abstract Pleurodires are less diverse than cryptodires, together forming the two major lineages of crown turtles. Their fossil record, however, is rich. A particularly large number pleurodires, many belonging to Podocnemidoidae, has been recovered from Upper Cretaceous Bauru Group outcrops south‐central Brazil. Herein we describe an additional pleurodire this region, Amabilis uchoensis gen. et sp. nov., based on a partially preserved skull. A. recognized as Podocnemidoidae by small entrance...
Los saurópodos titanosaurios son conocidos por mostrar una notable disparidad de tamaño corporal, con algunos taxones famosos acercarse al cenit del corporal un vertebrado terrestre. En este trabajo se describe nuevo titanosaurio – Ibirania parva gen. et sp. nov. Cretácico Superior (Santoniano–Campaniano) la Formación São José do Rio Preto Cuenca Bauru, el cual representa uno los más pequeños hasta fecha. El taxón puede diagnosticar gracias a siete autapomorfías y tenía longitud estimada 5.7...
ABSTRACT A skull and mandible of a new species notosuchian, Caipirasuchus paulistanus, belonging to the Sphagesauridae, were discovered in rocks Adamantina Formation (Bauru Basin: Late Cretaceous). The main autapomorphies are external naris bordered only by premaxillae; very high pterygoids ectopterygoids; palatines contacting maxillae cuneiform process; well-developed oval antorbital fenestra; premaxilla with four teeth; dentary ten teeth two diastemata; one diastema another between fourth...
Field work conducted by the staff of Centro de Pesquisas Paleontológicas Llewellyn Ivor Price Universidade Federal do Triângulo Mineiro since 2009 at Campina Verde municipality (MG) have resulted in discovery a diverse vertebrate fauna from Adamantina Formation (Bauru Basin). The baurusuchid Campinasuchus dinizi was described 2011 Fazenda Três Antas site and after that, preliminary descriptions partial crocodyliform egg, abelisaurid teeth, fish remains been done. Recently, fossil sample has...
Caipirasuchus is a genus of sphagesaurid notosuchian from the Bauru Basin (Upper Cretaceous), southeast Brazil. They were small-sized herbivorous/omnivorous animals, that measured around 1 metre in length, and had wide diversity geographical dispersion basin. Here, we diagnosed 6th species genus, originating sandstones Adamantina Formation municipality Catanduva, São Paulo State. presents significant variation morphology structures choana region. In particular, new has chambers wings...
Abstract Peirosauridae (Crocodyliformes, Notosuchia) is one of the fossil lineages crocodyliforms ubiquitous in Cretaceous deposits Bauru Basin. Here, we describe a new species longirostrine from Adamantina Formation (Bauru Basin, Late Cretaceous). The specimen consists partially preserved skull with cranial roof, interorbital region, and fragments posterior portion rostrum, including prefrontal lacrimal; left hemimandible, 14 alveoli 12 teeth; single cervical rib fragment. associated by...
A big semi-aquatic predator from the Bauru Basin, Adamantina Formation (Upper Cretaceous, Turonian-Santonian), in Brazil, was described this study. The new trematochampsid presents several synapomorphies with Itasuchus genus, and its autapomorphies are: presence of a groove region lachrymal-jugal suture; frontal cuneiform distal projection slightly inclined anteroposteriorly; dorsal surface squamosal is not arched finger-like occurs posterior portion; basicranium almost vertical only...
Isolated bones of abelisauroid theropods from the Bauru Group (Late Cretaceous, Brazil), are described.They correspond to three individuals represented by fused ischia and part ilium, a partial axis, right fi bula, respectively.The fossils come different sites in municipalities Ibirá (axis bula) Monte Alto (ilium ischia), São Paulo State, Maastrichtian beds José do Rio Preto Marília formations (Bauru Group), specimens provide new information on abelisauroids which still poorly known...
Abelisaurid theropods are well-know from the Cretaceous of several parts Southern Hemisphere, including South America, Madagascar, and Africa, but also in India Europe. Abelisaurids high-diverse among other with cervicocephalic specializations reaching medium/large sizes. In present contribution, we describe a new abelisaurid (Thanos simonattoi, gen. et sp. nov.) São José do Rio Preto Formation, Bauru Group, Brazil (Upper Cretaceous). Thanos differs by having well-developed keel becoming...
Aeolosaurus is a late Cretaceous Titanosaur genus with two species discovered in Argentina and one Brazil. Although the allocation of Argentinean seems unequivocal, that not case for Brazilian maximus since several authors questioned its positioning into this genus, based on both anatomical phylogenetic data. The revision diagnosis Ae. maximus, proposition new autapomorphy, corroborates uniqueness our analysis stresses relation to uncertain. Based upon that, we propose Arrudatitan, accommodate taxon.
A new species of a Crocodylomorpha Notosuchia from the Bauru Basin, Adamantina Formation (Upper Cretaceous, Turonian-Santonian), Brazil is described. The fossil consists distal portions skull and mandible. posterior teeth present globoid crown circular cross-section. Among notosuchians discovered in only Mariliasuchus presents similar teeth, however, arrangement these besides other autapomorphies, allow establishment taxa. This widens number diversity Notosuchia, showing success this clade...
Sphagesaurus montealtensis is a sphagesaurid whose original description was based on comparison with huenei, the only species of clade described to that date. Better preparation holotype and discovery new specimen have allowed review some characteristics identification several synapomorphies S. genus Caipirasuchus: presence antorbital fenestra; external nares bordered by premaxillae; premaxilla four teeth one diastema (between 3rd–4th teeth); between 4th premaxillary tooth 1st maxillary...
Resumo Uma nova especie de Crocodylomorpha Notosuchia proveniente da Bacia Bauru, Formacao Adamantina (Cretaceo Superior, Turoniano-Santoniano), e descrita neste estudo. O fossil consiste das porcoes distais do crânio mandibula. Observam-se dentes posteriores coroas globosas secao transversal circular. Dentre os notossuquios descobertos na Bauru apenas Mariliasuchus apresenta similares, no entanto, a distribuicao destes entre outras autapomorfias sustentam definicao novo taxon. Esta...
El presente trabajo reporta nuevos restos de anuros hallados en estratos referidos a la Formación Adamantina (Cretácico Superior) aflorantes las proximidades ciudad Catanduva, San Pablo, Brasil. Los representan dos individuos, uno ellos portador una cantidad características particulares, cranianas y postcranianas que permite asignarlo al género ya conocido Baurubatrachus. Hasta fecha, el estaba únicamente representado por holotipo Baurubatrachus pricei, recuperado Serra da Galga del...
This study presents the oldest historical record of fossil crocodyliforms in region Monte Alto, SP, besides analysis an additional from same site.The specimens come Marília Formation and they are only known local occurrences Crocodyliformes cranial fragments this stratigraphic unit.This expands knowledge about Bauru Basin contributes to definition regional paleofauna during Maastrichtian.
