Summary: This study describes limb bones and fossil shell remains from the upper Valanginian, Rosa Blanca Formation of Colombia, which shed light on the conditions and characteristics of large-size evolution in protostegid turtles.

Summary: This study provides new details on the cranial anatomy of the nodosaurid Hungarosaurus, identifying three different size classes representing various ontogenetic stages. The well-developed cranial ornamentation in early ontogenetic stages suggests a potential role in intra- and interspecific recognition. The observed variation in cranial ornamentation in Hungarosaurus appears to be associated with development, rather than the contribution of coossified osteoderms.

Summary: The record of Cretaceous pterosaur remains from Germany is sparse, with the discovery of a pterodactyloid pterosaur mandible from lower Valanginian strata of the Stadthagen Formation representing the first and only known pterosaur from the Valanginian of Germany.

Summary: This study reports and describes a new species of Strophodus, a hybodontiform shark, based on isolated teeth collected in ValanginianHauterivian rocks of the Rosa Blanca Formation in Colombia. It also describes fragmented teeth assigned to Strophodus sp. from the same formation. The discovery of this new species expands our understanding of the paleogeographic distribution and paleodiversity of hybodontiform sharks in South America, particularly in the Cretaceous period.

Summary: This study reports the discovery of new Mesolithic human remains in Arma di Nasino, Liguria, northwestern Italy, and reveals their ecological dependence on high-altitude resources, which is the first evidence of an ecological shift in northwestern Italy following deglaciation. The analysis also provides detailed information on the life experience of a specific female forager, including skeletal trauma, developmental disturbances, and resilience.

Summary: A new well-preserved spinicaudatan species named Yanjiestheria huajiyingensis sp. nov. is described from the Huajiying Formation in northern Hebei, northern China. This species is distinguished by the presence of transverse ridges in the postero-ventral part of the carapace. Preserved eggs in the new species provide insights into sexual dimorphism in Yanjiestheria.

Summary: The discovery of Upper Cretaceous dinosaur fossils in the Western Desert of central Egypt adds to the limited record of dinosaurs in the region. The fossils include various types of dinosaurs, such as titanosaurian sauropods and non-avian theropods, indicating a diverse ecosystem supporting non-avian dinosaurs in Late Cretaceous North Africa.

Summary: The newly discovered taxa Bructerodon alatus gen. et sp. nov. and Cheruscodon balvensis gen. et sp. nov. from the Lower Cretaceous Balve locality in Germany have distinct dental features and show some differences from other known similar taxa.

Summary: This study systematically investigated the background structure and petrogenetic significance of Early Cretaceous magmatic rocks in the Badaguan area of northern Daxing'anling, as well as the Late Paleozoic tectonic evolution of the Mongol-Okhotsk suture zone. The results suggest that the magma originated from the partial melting of basal crustal materials and underwent fractional crystallization processes. This study provides important information for understanding the geological evolution of the region.

Summary: This paper reports the first occurrence of the belemnite species Liobelus acrei in the Lower Cretaceous of the Vocontian Basin in southeast France. This finding revises the previously known spatial distribution pattern of boreal belemnites. The Valanginian belemnite assemblages in this area are dominated by genera of Tethyan ancestry, indicating an isolated immigration of boreal belemnites in the early Valanginian. The different distribution patterns shed new light on the ecology, migration patterns, and evolution of Early Cretaceous belemnites.

Summary: Deinosuchus, a neosuchian animal, has been discovered in the Campanian formations in North America, with fossils found from New Jersey to Montana in the USA and as far south as Coahuila in Mexico. Fossils of Deinosuchus found in the Menefee Formation in New Mexico represent one of the earliest occurrences of this genus on the Laramidian subcontinent, with distinctively morphological osteoderms bearing similarities to those of Deinosuchus.

Summary: Dinosaur research in Australia has seen a revival in the past decade, leading to a better understanding of the mid-Cretaceous fauna. Ankylosaurs, a rare but significant group, have been found in various dinosaur formations across Australia. In this study, a partial ankylosaur skull was described from Queensland, Australia, which represents the oldest ankylosaurian material in the region. The skull was reconstructed using synchrotron radiation X-ray tomography, revealing the palatal anatomy of Australian ankylosaurs.

Summary: This study identified a fossilized embryonic turtle preserved in an egg from the Upper Cretaceous of China, attributed to the extinct group Nanhsiungchelyidae. Despite habitat differences, nanhsiungchelyids and adocids shared reproductive traits such as thick eggshells, medium size clutches, and relatively large eggs.

Summary: The newly discovered large fossils from the early Neoproterozoic marine deposits in Canada represent multicellular eukaryotic macroalgae with a possible green algal affinity, shedding light on the origin and evolution of photosynthetic eukaryotes in marine environments.
