Summary: Notosuchians are a diverse group found in rocks of the Upper Cretaceous Bauru Group in southeastern Brazil, occupying various terrestrial ecological niches. The Uberaba Formation is one of the most prolific Upper Cretaceous units in Brazil, with the discovery of a new taxon, Eptalofosuchus viridi, and other notosuchian remains.

Summary: The Cretaceous climate was characterized by arid and semiarid conditions around the world, with significant paleoclimatic reconstructions being developed in the Bauru Basin of Brazil due to the well-preserved sedimentary sequences and abundant fossil content. By studying the paleosols in the basin, researchers identified environmental and climatic patterns from the Lower to Upper Cretaceous, allowing for the elaboration of maps of paleoclimatic evolution that contribute to the understanding of Cretaceous paleoclimatic context in South America.

Summary: The superfamily Lepisosteoidea, known as gars, is the only group of extant ginglymodian fishes with roots dating back to the Mesozoic. This superfamily consists of one family, two genera, and seven species. The fossil remains discovered in Brazil provide new insights into the origins and distribution of Lepisosteoidea, and suggest possible vicariance or dispersal events that led to their presence in South America.

Summary: This study focuses on the northeastern deposits of the Marilia Formation in the Bauru Basin of SE Brazil, demonstrating significant differences from other regions and proposing a new lithostratigraphic classification as the Serra da Galga Formation. By analyzing lithofacies, palaeopedology, and sedimentary architecture, the study reveals unique characteristics of these deposits, distinguishing them from the rest of the Marilia Formation.

Summary: This research provides detailed histological descriptions of severe bone inflammation and the exceptional preservation of soft-bodied parasitical microorganisms in the vascular canals of a non-avian dinosaur for the first time, bringing new insights to parasitology, pathology, and histology. An old titanosaur from Southeast Brazil in the Upper Cretaceous exhibited acute osteomyelitis, with tens of parasites found in the specimen's vascular canals, indicating a potential association between parasitic infestation and infectious bone disease.

Summary: This study analyzed the dental histology of three notosuchians commonly found in the Upper Cretaceous rocks of the Bauru Group, revealing differences in tooth formation among these taxa. Mariliasuchus had faster tooth growth compared to Sphagesauridae and Baurusuchidae, with thicker enamel. The substantial development of enamel in the chewing area of Sphagesauridae suggests they are more adapted to process food items than more basal forms like Mariliasuchus.

Summary: Occurrences of young and immature individuals in the fossil record provide important morphological and evolutionary information about a lineage's development. This study describes skeletal material of a small notosuchian yearling with features consistent with a baurusuchid affinity, contributing to our understanding of notosuchian ontogeny and diversity. The findings reveal distinct morphological characters in the young individual compared to most adult forms, shedding light on growth characters to be integrated into future phylogenies.

Summary: This study applied Finite Element Analysis to investigate the functional morphology of the tooth and ungual phalanges of Vespersaurus paranaensis. Results suggest that the tooth was adapted for a 45-degree bite angle and not suited for struggling prey or harder food items. The analysis of the ungual phalanges indicates that they were similar in shape to those of living mammals with scansorial, fossorial, and terrestrial habits. Overall, this suggests that Ves. paranaensis had a generalist diet, hunting small vertebrates, invertebrates, or immobile prey.

Summary: The new Pleurodira turtle Itapecuruemys amazonensis from the Parnaiba Basin in Brazil is described, with its most peculiar feature being the arrangement of neural plates six and seven. This new species, along with Cearachelys and Galianemys spp., contributes to the paleoherpetological diversity of the Itapecuru Formation.

Summary: The study applied high-resolution sequence stratigraphy to analyze Cretaceous fluvial deposits in the Potiguar Basin, aiming to improve reservoir management and production optimization. By interpreting different facies associations and stratigraphic surfaces, it identified zone boundaries and various sequences, establishing a more predictive reservoir zonation that enhances production efficiency and oil reserves in the oil fields.

Summary: Multi-scale transgressive-regressive cycles from the mid-Jurassic were identified in the Central Lusitanian Basin, Portugal. These cycles help to understand the depositional evolution of the basin and construct stratigraphic sequences. The stacking pattern of high-frequency sequences forms larger clusters that define medium-frequency sequences. Integration of various methods supported the interpretation of facies associations and provided insight into the Middle-Upper Jurassic disconformity. This study has implications for similar successions and depositional settings in other regions.

Summary: A paleoparasitological analysis of a large coprolite from the Touro Passo Formation in Brazil revealed the presence of 14 protozoan oocysts and three nematode eggs, suggesting they belong to orders Eucoccidiorida and Strongylida, representing parasitic species in the alimentary tract of modern carnivores. This discovery marks the first record of paleoparasites in a vertebrate host from the Touro Passo Formation.

Summary: This document presents a study comparing the spectra of large-magnitude seismic records in Chile between 2012 and 2022 with the design spectra of NCh433 and D. S 61. The aim is to determine if Chile's seismic-resistant regulations are updated to the existing reality and propose new design spectra that better represent the seismic activity in Chile during the last decade.

Summary: This study investigated the presence of 15 toxic metals in surface sediment in a tropical river ecosystem in Cuba. The results showed that the sediments had higher concentrations of four metals compared to Cuban norms. Various contamination indices were calculated, and correlations analysis revealed the main sources of contamination. The study provides important information for the management of the river and emphasizes the need for metal pollution control and monitoring.

Summary: Lanin volcano is a composite volcano in the Andes, which has erupted lava flows with different compositions. The volcano's magma reservoir contains a crystal mush, and the pre-eruptive conditions include temperature, pressure, and oxygen fugacity. Fractional crystallisation has led to the evolution of the magma with different compositions.

Summary: This study investigates the role of wedge integrity on the frequency content of strong ground motion produced by subduction earthquakes in Northern Chile. The results show that the frequency characteristics of seismic waves vary with hypocentral distance, indicating lateral variations in anelastic attenuation due to the heterogeneous tectonic structure.
