Abstract
Post-Triassic theropod, sauropodomorph, and ornithischian dinosaurs are readily recognized based on the set of traits that typically characterize each of these groups. On the contrary, most of the early members of those lineages lack such specializations, but share a range of generalized traits also seen in more basal dinosauromorphs. Here, we report on a new Late Triassic dinosaur from the Santa Maria Formation of Rio Grande do Sul, southern Brazil. The specimen comprises the disarticulated partial skeleton of a single individual, including most of the skull bones. Based on four phylogenetic analyses, the new dinosaur fits consistently on the sauropodomorph stem, but lacks several typical features of sauropodomorphs, showing dinosaur plesiomorphies together with some neotheropod traits. This is not an exception among basal dinosaurs, the early radiation of which is characterized by a mosaic pattern of character acquisition, resulting in the uncertain phylogenetic placement of various early members of the group.

Aeolosaurus maximus

Oxalaia quilombensis

Oxalaia quilombensis xx, 2011

Place: Alcântara Formation, Itapecuru Group, Parnaíba Basin, Itapecuru-Mirim, Maranhão State
Time: Cenomanian, Early Cretaceous;
Size: 14-15m;
Taxonomy: Theropoda, Tetanurae, Spinosauroidea, Spinosauridae.

A new spinosaurid taxon, Oxalaia quilombensis gen. et sp. nov., is described based on the anterior part of a snout and a fragment of a maxilla. These specimens were collected at the Laje do Coringa site, Late Cretaceous (Cenomanian) of the São Luis Basin. Unlike Cristatusaurus and Suchomimus, Oxalaia quilombensis lacks serrations on the teeth. The new species differs from Angaturama limai by having the anterior part of the premaxillae more expanded and by lacking a sagittal premaxillary crest. It further differs from Spinosaurus cf. S. aegyptiacus and the Algerian spinosaurid by the rounder shape of the terminal expansion. Furthermore, xalaia quilobensis has one functional tooth followed by two replacement teeth, a feature not previously observed in theropods. Oxalaia quilombensis appears to be more closely related to the spinosaurids found in North Africa than to the Brazilian members of this clade and thus further increases the diversity of these enigmatic predatory dinosaurs in this country.

Tapuiasaurus macedoi

2011-02-08T07:50:00.000-08:00

Tapuiasaurus macedoi Zaher, Pol, Carvalho, Nascimento, Riccomini, Larson, Juarez-Valieri, Pires-Domingues, Silva Jr & Campos, 2011

Place: Quiricó Formation, near Coração de Jesus, Minas Gerais State;
Time: Early Cretaceous - Aptian;
Size: ?.
Etymology: From ‘‘Tapuia’’, a generic name from the Jês indigenous language family used to designate tribes that inhabited the inner regions of Brazil, and sauros, Greek for lizard. The
specific name honors Ubirajara Alves Macedo, who first discovered the deposits near Coração de Jesus.

Original Abstract:

Advanced titanosaurian sauropods, such as nemegtosaurids and saltasaurids, were diverse and one of the most important groups of herbivores in the terrestrial biotas of the Late Cretaceous. However, little is known about their rise and diversification prior to the Late Cretaceous. Furthermore, the evolution of their highly-modified skull anatomy has been largely hindered by the scarcity of well-preserved cranial remains. A new sauropod dinosaur from the Early Cretaceous of Brazil represents the earliest advanced titanosaurian known to date, demonstrating that the initial diversification of advanced titanosaurians was well under way at least 30 million years before their known radiation in the latest Cretaceous. The new taxon also preserves the most complete skull among titanosaurians, further revealing that their low and elongated diplodocid-like skull morphology appeared much earlier than previously thought.

Marília Formation

2009-11-02T07:54:00.000-08:00

The Marilia Formation is part of the Bauru Group. It's named after Marilia, Sao Paulo State, but it included locations in Minas Gerais and Goias State too. Its age is dated from Upper Maastrichtian, in Latest Cretaceous.

A Formação Marília é parte do Grupo Bauru. Apesar de nomeada a partir de terrenos situados no município de Marília, Estado de São Paulo, apesar de incluir sítios nos estados de Minas Gerais e Goiás. Sua idade é considerada como do Maastrichtiano Superior, a última divisão do período Cretáceo.

Uberaba Formation

The Uberaba Formation is part of the Bauru Group. It is located in Uberaba, Minas Gerais State. This formation has yielded only disarticulated dinosaur specimens. Santucci (2002) noted that sauropod remains from the Uberaba Formation represent possibly basal titanosaurs.

Description:
A new titanosaurid, Baurutitan britoi n. gen., n. sp., is described and compared with other taxa
of that sauropod clade. The specimen (MCT 1490-R) consists of the last sacral followed by a sequence of 18 caudal vertebrae that were found in the continental deposits of the Late Cretaceous Bauru Group that outcrop at the Peirópolis region, near the town of Uberaba, State of Minas Gerais, Brazil. This new taxon is distinguished from other titanosaurians by several features, including subrectangular to square outline of the anterior articulation surface of the anterior and middle caudals, strongly pointed laterally directed process intercepting the spinoprezygapophyseal lamina in caudal 1; dorsal prezygapophyseal tuberosity on the lateral margin of the prezygapophyses of caudals 2-4, that smoothens out in midcaudals. This material
demonstrates that the horizontal ridge present in middle and posterior caudals of some titanosaurs, in Baurutitan britoi is homologous with a dorsal tuberosity and not with the transverse process.

Description:

A new titanosaurid dinosaur from the Late Cretaceous continental deposits of the Bauru Group
is described. Trigonosaurus pricei n.gen., n.sp., is based on two specimens, both collected at the Caieira Quarry near Peirópolis, Minas Gerais. The holotype consists of the five most posterior cervical vertebrae, 10 dorsals, six sacrals and the left ilium (MCT 1488-R). The second specimen (paratype) consists of 10 caudal vertebrae that according to a quarry map, were found isolated but show a similar morphology and compatible size suggesting that they belonged to one individual (MCT 1719-R). Trigonosaurus pricei is diagnosed by a combination of characters such as elongated cervicals and middorsals, dorsal vertebrae 9 and 10 with incipient postzygodiapophyseal lamina and transverse processes well developed throughout the sequence formed by anterior and medial caudals. The occurrence of this new taxon indicates a higher diversity of titanosaurids in the Brazil during the Cretaceous period.

Description:

It is the biggest dinosaur found in Brasil, a titanosaur characterized by the following combination of features: tail composed of anterior and midposterior caudal vertebrae with the anterior (and posterior) surface of the centrum dorsoventrally compressed; midposterior caudal vertebrae with the lateral surface of the centrum strongly concave (spool-shaped); dorsal margin of neural spine in midposterior caudal vertebrae inclined anteriorly; presence of at least one midposterior caudal with biconvex centrum; metacarpal IV about 12% shorter than metacarpal II; sacral centrum with keel-shaped ventral surface. Associated material – The distal end of a right scapula (MN 7048-V) and two sternal plates (MN 7049-V and MN 7050-V) of a second animal attributed to Maxakalisaurus
topai, one caudal vertebra (MN 7051-V) that may or not pertain to this species, and crocodylomorph and theropod teeth.
