Summary: Polydolopidae is a family of Palaeogene marsupials found in outcrops in southern South America and the Antarctic Peninsula. Through taxonomic revision and phylogenetic analysis, new genera and species within the family have been identified. The family appeared in the early Palaeocene and went extinct during the Early Oligocene, possibly due to climatic deterioration.

Summary: This study describes three genera and four species of phyllocarids, including one new genus and two new species, based on specimens from the Fentou Formation in Wuhan, China. The study expands the known morphological range of phyllocarids and has implications for the functional morphology, taxonomy, and evolution of archaeostracans as a whole.

Summary: The water scavenger beetle subfamily Acidocerinae, with over 500 described species, is cosmopolitan and ecologically diverse. Phylogenetic analyses revealed most genera to be reciprocally monophyletic, with some exceptions. The lineage is estimated to have originated in South America + Africa during the mid-Jurassic, with South America and Africa remaining important areas of endemism throughout its evolution.

Summary: The study conducted a phylogenetic analysis of the Pectinidae family in South America based on a large morphological matrix, identifying two new monophyletic clades. The tribe diverged at the Eocene-Oligocene boundary with complex evolutionary history, characterized by ghost lineages and monophyletic genera.

Summary: The oldest archosauromorphs are found in middle-upper Permian rocks, but their taxonomic richness and diversity increased significantly after the Permo-Triassic mass extinction. Fossil records from southern Africa, Europe, and Asia contribute to the early evolutionary history of Archosauromorpha, while South America has a more complete fossil record in the Late Triassic. Recent research on South American fossils has improved our understanding of this group, but more work is needed to expand the Early Triassic record, obtain more Middle Triassic specimens, and clarify the taxonomy of specific groups.

Summary: Researchers re-described the specimen of Bolotridon frerensis using computed tomography (CT) reconstruction, providing new information on its palatal and internal anatomy. New endocranial characters identified for this taxon suggest a more crownward phylogenetic position than previously hypothesized.

Summary: A new fossil dolphin, Nihohae matakoi gen. et sp. nov., from the Late Oligocene of New Zealand, reveals a diverse dentition with a variety of tooth shapes and orientations, including horizontally procumbent tusk-like teeth. This suggests adaptive advantages for horizontally procumbent teeth in basal dolphins.

Summary: This study reviews the influence of tectonic evolution in the Tethyan region on the evolution and diversity patterns of Eurasian animals. The tectonic evolution in the Tethyan region directly impacts the composition and spatial distribution of Eurasian animal diversity, as well as animal origin, dispersal, preservation, diversification, and extinction. The Cenozoic tectonic evolution of the Tethyan region plays a significant role in shaping the changes in Eurasian animal distribution.

Summary: The expansion of open habitats in the forests of west-central North America may be linked to a decrease in winter precipitation, rather than solely to changes in temperature or drier summers.

Summary: This study examines the relationship between diet, climate, locomotion, and intestinal anatomy in 390 bird species. The results show that intestinal length is influenced by multiple factors, including diet composition, habitat condition, and flight capability. Additionally, the study finds systematic differences in intestinal anatomy between birds and mammals.

Summary: Arboreal species of the genus Prosopis have been extensively studied in arid and semi-arid ecoregions of South America. This systematic review examines the relationship between Prosopis species growth and water, focusing on the spatial distribution of research sites and the findings from dendrochronological and hydrological studies. The review highlights the unique adaptability of Prosopis to arid conditions and its potential as a proxy for historical droughts and water variability. It also suggests opportunities for expanding the geographical and climatological scope of Prosopis research and incorporating novel techniques to better understand hydrological changes throughout South America.

Summary: Our study reconstructs the palaeogeography of the northern part of the Lesser Antilles to analyze potential emerged areas during the Cenozoic era, allowing for terrestrial faunal dispersals between South America and the Greater Antilles. It reveals sequences of uplift and emergence during specific periods, indicating the existence of episodic mega-islands and transient terrestrial connections between different regions.

Summary: Recent research has identified the basal beds of the lower section of the Lumbrera Formation as early Eocene deposits dating between 55-46.2 Ma, based on a succession of hyperthermal events. The study also presents one of the oldest cingulate assemblages in America from the early Eocene hyperthermal period, indicating an early diversification of the Cingulata during the Paleocene.

Summary: A new remain of a SANU, named Kyraodus churcalensis gen. et. sp nov., is described from the lower levels of the Lumbrera Formation. It possesses distinct features such as brachydont and bunodont molars, a larger talonid compared to the trigonid, and an intact distal wall of the metaconid. Cladistic analysis revealed its position within a clade including Mioclaenidae, Litopterna, Didolodontidae, and Phenacodontidae, separate from Notoungulata plus Kollpaniidae. This study highlights the significance of Northwestern Argentina for the early radiation of native ungulates.

Summary: The Quebrada de Los Colorados Formation in Northwestern Argentina has recently revealed a new faunistic assemblage of South American native ungulates, increasing the taxonomic richness known for this formation. The presence of new species suggests a possible ungulate migration from Patagonia to Northwestern Argentina during the Eocene. The observed taxonomic differences among different formations in Northwestern Argentina may be related to orogenic factors rather than sampling biases.
