Summary: The Mambawakale ruhuhu fossil specimen from the Manda Beds of southwest Tanzania provides important insights into the early radiation of archosaurian reptiles. It possesses unique cranial features that distinguish it from other archosaurs in the Manda Beds, and is considered to be an early diverging pseudosuchian. It is one of the largest pseudosuchians known from the Middle Triassic.

Summary: A new pachypleurosaurid, Luopingosaurus, with a long snout and hyperphalangy in the manus, is discovered in China, providing new insights into the evolution and biogeography of this group. The reduction of hyoid length to mandibular length ratio and the increase of snout length in pachypleurosauroids suggest a gradual recession of suction feeding. Phylogenetic analysis supports a western Tethyan origin for this family.

Summary: In this study, a new pachypleurosaurid species, Honghesaurus longicaudalis, from Yunnan, China is reported. This discovery fills the morphological gap in pachypleurosaurs and provides new evidence and insights into this group. The study also reveals the role of the Tethys Ocean in the dispersal of pachypleurosaurs from Europe to South China.

Summary: This study introduces a new Late Triassic archosaur, Incertovenator longicollum, with unique character states placing it within early avemetatarsalian and pseudosuchian archosaur clades. Through phylogenetic analyses, it is identified as either an early diverging avemetatarsalian or a loricatan closely related to Mandasuchus tanyauchen.

Summary: Based on field geological survey, seismic data interpretation and analysis of drilling and logging data, this study analyzed the geological structure evolution, stratigraphic sedimentary filling sequence, and sedimentary system around Bogda Mountain. The tectonic evolution was divided into nine stages, with the Middle-Late Permian to Middle-Late Triassic period characterized by the development of intracontinental rift, foreland basin, and inland depression basin, resulting in different sedimentary facies such as lake, fan delta, and braided river delta.

Summary: The study reveals that during the Middle Triassic, the Hexi Corridor and the western Ordos Basin shared a common source, but in the Late Triassic, sediments in the Hexi Corridor mainly originated from the Qilian-Qaidam Terrane, while the source of the western Ordos Basin remained unchanged. It also suggests that the Hexi Corridor was temporarily connected with the Ordos Basin during the Middle Triassic, but was separated by a small-scale, underwater paleo-uplift during the Late Triassic.

Summary: This study used hierarchical cluster analysis, ordination methods, and bipartite network analysis to study the phytogeographic units of the Middle-Upper Triassic of Gondwana. The results showed a clear separation between tropical and extratropical associations, and identified a microfloristic region in southwestern Gondwana that is similar to the microfloras of northern Laurasia. These findings confirm, for the first time through quantitative methods, the distinction between different microfloras.

Summary: Lewisuchus admixtus is an early dinosauriform species described based on a single incomplete skeleton in 1972. Recent discoveries of two partially articulated skeletons in Argentina have provided significant new information on the anatomy and taxonomy of early dinosauriforms.

Summary: The Triassic of South America is known for its diverse fossil assemblage, including various terrestrial tetrapods. However, carnivore archosaurs are rare in Brazilian Norian outcrops. A new tooth fossil discovered at the Sa similar to o Luiz site in Brazil provides evidence of a previously unidentified medium/large-sized carnivorous archosaur.

Summary: The study examines the impact of global and local humid climate events during the Middle-Late Triassic on paleontological evolution and mineral distribution. Analysis of the Yanchang Formation in the Ordos Basin reveals humid climate events during the Ladinian-Carnian period, leading to enhanced hydrological cycles.

Summary: This research report presents a multidisciplinary geoarchaeological investigation of the sedimentary sequence at the La Roche-a-Pierrot site in Saint-Ce & PRIME;saire, France. They propose a site formation model and shed new light on spatial inconsistencies in the archaeological sequence, providing a rigorous framework for further archaeological research at the site.

Summary: This study focuses on a high-resolution stratigraphic, sedimentologic, petrographic, and limnogeological investigation of the Agua de la Zorra depositional system to understand its evolution through space and time and to reconstruct the development of the carbonate factory within the palaeolake. The results strongly support volcanism and tectonics as the main allogenic factors controlling the Agua de La Zorra lacustrine system evolution.

Summary: This study investigates the benthic foraminiferal assemblage from the Um Rigl succession in the northwest of Fayoum area, Egypt. Two rock units, the Gehannam Formation and Birket Qarun Formation, are recognized stratigraphically. A total of 63 species are identified and analyzed to establish a benthic foraminiferal biozone and two ecozones.

Summary: Hadrosaurid (duck-billed) dinosaur bonebeds are commonly found in the upper Cretaceous strata of the Midwest of North America, but less frequent in more northern regions. The rediscovery of the Spring Creek Bonebed in the Wapiti Formation of northwestern Alberta revealed the first documented occurrence of lambeosaurines in the formation. The site also provided evidence suggesting age segregation as a life history strategy among hadrosaurids during their late juvenile stage, contributing to their diverse and cosmopolitan nature.
