Summary: This study describes a new proterochampsid with a well-preserved hind limb, which contributes to the understanding of the hind limb anatomy of this group. The new taxon exhibits unique traits that provide insights into the evolutionary origins of certain muscle attachment structures. The specimen suggests that some archosaurian features evolved earlier than previously thought, shedding light on the evolutionary context of Archosauria.

Summary: Past major biological turnovers are associated with large injections of CO2 into the atmosphere-ocean system, often related to the formation of Large Igneous Provinces. However, the effects of these CO2 pulses on ecosystems vary at different times, depending on the initial conditions. This study uses biogeochemical and climate modeling to show how delayed vegetation recovery and the amalgamation of Pangaea influenced the Late Triassic Carnian Pluvial Episode. The findings provide insights into the mechanisms behind this global climate change event and its connection to a major biological turnover and the emplacement of the Wrangellia LIP.

Summary: The Late Triassic Carnian Pluvial Episode (CPE) was a globally significant event characterized by increased temperature and humidity, leading to changes in terrestrial vegetation and freshwater algae abundance. This event ended a long period of arid climate and is associated with volcanic activities of the Wrangellia Large Igneous Province (LIP) that released greenhouse gases. The volcanic emissions enhanced atmospheric circulation and hydrological cycle, resulting in a shift from arid to humid conditions that affected floral composition. The increased terrestrial carbon burial counteracted the warming effects of volcanic emissions, ultimately leading to a return to a stable climate state.

Summary: The Late Triassic Carnian Pluvial Episode saw a significant increase in global humidity and temperature, linked to the large-scale volcanism of the Wrangellia large igneous province. New research shows that volcanic eruptions during this period occurred in multiple discrete pulses, each associated with climatic changes and ecological turnover.

Summary: During the Late Triassic Carnian Pluvial Episode (CPE), significant pelagic calcification began with the appearance of Orthopithonella calcispheres in deep-water successions of the Western Tethys, constituting up to 8% of hemipelagic limestones. This change in carbonate sedimentation may indicate a profound modification in ocean biogeochemistry during the CPE.

Summary: Research indicates that during the Late Triassic Carnian Pluvial Episode, volcanic activity may be linked to multiple carbon inputs into the atmosphere-ocean system and enhanced hydrological cycle. New data suggests that volcanic Hg inputs into basins may be associated with CPE global negative C-isotope excursions and humid phases.

Summary: The early evolution of theropod dinosaurs remains poorly understood. A newly named dinosaur, Erythrovenator jacuiensis, from Triassic deposits in Brazil, represents one of the oldest theropods globally, with unique features shedding light on early theropod characteristics and enriching our understanding of the faunal content in the assemblage.

Summary: Loricata refers to a group of hypercarnivorous pseudosuchian archosaurs that were top predators in the Middle to Late Triassic ecosystems. Fossil records of this group are abundant in the lower portion of the Santa Maria Supersequence in southern Brazil, but become scarce or absent in subsequent units. Therefore, studying new specimens from these units is important. A new fragmentary specimen of Loricata from the lower Candelária Sequence is reported here, supporting its loricatan affinities through morphology and phylogenetic analysis.

Summary: The Carnian Pluvial Episode was a short interval of extreme rainfall in the Late Triassic that caused significant changes in marine ecosystems. This study examined an equatorial record of oceanic conditions during this episode and found that global warming induced by volcanism led to oceanic anoxia, resulting in a turnover in marine taxa and an increase in radiolarian diversity after the recovery from anoxia.

Summary: The study investigates the early avemetatarsalians and their common ancestor's morphology, but is limited by a lack of fossil records. A newly discovered early-diverging avemetatarsalian from Madagascar helps fill in these gaps. The specimen indicates that osteoderms were present in the earliest avemetatarsalians but were lost in later lineages, shedding light on the coexistence of non-dinosaurian avemetatarsalian clades during the Middle-Late Triassic transition in Gondwana.

Summary: The Triassic period witnessed significant changes in marine and terrestrial ecosystems. The recovery from the Permian-Triassic mass extinction was followed by a period of renewal and novelty, which was enhanced by the effects of the Carnian Pluvial Episode. The oceans experienced changes in the carbonate factory and the Mesozoic Marine Revolution during the Middle and Late Triassic, contradicting the previous belief that these occurred in the Late Jurassic and Cretaceous. On land, there was a competition between synapsids and archosauromorphs, leading to a shift in posture and physiology, including the development of warm-bloodedness. This shift in ecosystems and adaptations was triggered by the mass extinction event and further accelerated by the Carnian Pluvial Episode.

Summary: The Carnian Pluvial Episode was a global environmental change and biotic crisis that occurred during the Carnian period, with evidence linking it to the eruption of Wrangellia Flood Basalt volcanism. High-resolution microfossil biostratigraphy and paleo-seawater Os isotope data were used to study the temporal relationship between the eruption and CPE, revealing a decline in Os isotope ratios during the Julian period and evidence of reducing conditions during the CPE in the Panthalassa Ocean.

Summary: Crocodylomorpha is the stem-lineage of modern crocodylians that survived the Triassic-Jurassic mass extinction event. Saltoposuchus connectens is one of the first described crocodylomorph species but its taxonomy has been contentious. In this study, additional specimens of Saltoposuchus are described in detail, its taxonomy is revised, and its relationship with other crocodylomorphs is investigated.

Summary: Birds and mammals are successful in modern ecosystems due to their endothermy. The stepwise emergence of endothermy began in the Late Permian but accelerated in the Early Triassic, triggered by the Permian-Triassic mass extinction. In the Triassic, an arms race between synapsids and archosauromorphs led to the initial dominance of dinosaurs and pterosaurs.

Summary: This study describes two insect leaf mines from the Late Triassic in Argentina, including the earliest record of a blotch mine. The discovery suggests that strategies of endophytic herbivory diversified earlier than previously thought. The study also highlights the opportunity to consider possible producers of these interactions and re-evaluate plant host diversity and adaptations to insect herbivory based on the exceptional preservation of fossils.

Summary: The origins of blood cell production in long bones have been a topic of interest with recent studies suggesting that Permian tetrapods may have been among the first to exhibit a centralised marrow organisation. This sheds light on the early evolution of limb-bone development and bone-marrow functional acquisitions.

Summary: Analyses of coprolites provide valuable data on animal feeding and food quality, shedding light on the taxonomy of the environment. This study describes plant remains found in coprolites from early Hettangian deposits at Soltykow, Poland. The coprolites are likely from herbivorous sauropodomorphs, ornithischians, and large carnivorous theropods. The findings suggest that herbivores fed on flora from a fluvial plain, while coprolites of large predators contained diverse plant remains likely ingested from prey. Palynological analysis revealed a variety of plant taxa, with Classopollis torosus dominating the sporomorph assemblage.
