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.

ABSTRACTLittle is known about the tooth wear of South American theropod dinosaurs. This paper describes wear facets in Abelisauridae, Carcharodontosauridae and some indeterminate theropods teeth, from the Marília Formation. Four types of wear facets are proposed: vertically-oriented attritional striations; perpendicular attritional surfaces; oval wear facets; and apical grooves. All these worn surfaces were produced by dental occlusion, except the apical grooves, which are produced by the contact between predator teeth and the prey bone during predator–prey interaction. More detailed biomechanical and hardness testing of teeth and bone may further elucidate the pattern of tooth wear in theropods.

Peirópolis is a quarter located in Uberaba County (Minas Gerais State) that has an extraordinary paleontological site of the Late Cretaceous period. This area has many vertebrate fossils, mainly dinosaurs. A great amount of these fossils were found in sandstones of the serra do Veadinho. However, a lower limestone level was economically mining by European's immigrants between 1890 and 1960. In this period, the explotation was accomplished through manual exploration's techniques contributing to the discovery of fossils. Although, in 1987, the mineral explotation was conducted through mechanical techniques, causing environmental impacts and fossil destruction. Therefore, a judicial dispute has started to the use and occupation of the area between the miner activity, local population and geoscientists. Nowadays, the area is for exclusive use of the paleontological research and, in the future, touristic activity. In this context, was analysed a historic review of the use and occupation of serra do Veadinho to examine the compatibility between miner activity and paleontological research.
