Summary: The study shows that the Cretaceous-Paleogene mass extinction event had a significant impact on European freshwater gastropod species, resulting in the extinction of 92.5% of species. The extinction phase lasted for 5.4 million years, followed by a recovery period of 6.9 million years. Present extinction rates for European freshwater gastropods are three orders of magnitude higher than the revised estimates for the Cretaceous-Paleogene mass extinction.

Summary: The Agriopleura event signifies the regional extinction of the rudist genus Agriopleura in northwestern Europe and is associated with environmental and biological changes. It marks the boundary between two distinct late Barremian regional rudist assemblages. The subsequent Palorbitolina episode coincides with a rudist eclipse. The recovery phase is characterized by new species and a low extinction pattern, with a burst of speciation and the entry of Caprinidae.

Summary: Dire wolves, common in Pleistocene America, were found to have diverged from living canids around 5.7 million years ago and evolved in isolation from ancestors of grey wolves and coyotes. There is no evidence of gene flow between dire wolves and North American grey wolves or coyotes, indicating a distinct evolutionary history. Our results also support an early New World origin of dire wolves compared to the Eurasian ancestors of other canids.

Summary: A tooth from the Late Cretaceous in Argentina suggests the presence of monotremes in South America at the end of the Mesozoic Era. Monotremata, a group of egg-laying mammals represented by the platypus and echidnas, is endemic to Australia and nearby islands. The discovery of a Late Cretaceous monotreme in southern Argentina indicates their presence in circumpolar regions and suggests that their distinctive anatomical features were already present in ancient forms.

Summary: Late Quaternary climatic fluctuations had significant impacts on the extinction of large mammal species, including the giant deer. Genetic analyses of mitogenomes revealed five main clades for the species, with a decrease in genetic diversity during the Last Glacial Maximum. This reduction, along with a contraction of fossil occurrences, suggests that climate played a major role in the extinction of the giant deer.

Summary: The latest research on Cloggs Cave reveals that the youngest megafaunal specimens date back to 44,500-54,160 years ago, more than previously believed, aligning with the continental pattern of megafaunal extinctions. This suggests that the extinction of these megafauna could not have been caused by climate change leading into the Last Glacial Maximum.

Summary: This study focused on the structural setting of a small area of the Murge Plateau in southern Italy, documenting the influence of Late Cretaceous transtensional faulting on the geological features through field geological and structural mapping, as well as mineralogical and petrographic investigations of rock samples. The results indicate a few km-long transtensional fault system formed by high-angle faults and dilational fissures, leading to the development of karst-related features. The study suggests that the Late Cretaceous transtensional faulting on the Apulian Platform was likely associated with orogenic processes involving the northern edge of the Adriatic micro-plate.

Summary: Turtles are the only amniotes that lay aragonitic eggs. A discovery in Montana, USA, confirmed the existence of aragonite in turtle eggs dating back to at least the Campanian period, around 76 million years ago. This finding supports the hypothesis that aragonitic eggshell is a unique feature of all turtles and suggests high-quality, unaltered paleoenvironmental information can be obtained from localities with aragonitic turtle eggs.

Summary: This study integrates basin-scale, three-dimensional sequence architecture, molluscan biostratigraphy, and carbon-isotope chemostratigraphy to demonstrate synchronous sea-level changes in the Western Canada Foreland Basin and the Bohemian Cretaceous Basin. The results show that major transgressive events in both basins were paced by different eccentricity cycles, while early Coniacian sequences were influenced by the obliquity rhythm. The findings provide new insights into the mechanisms of eustatic change and fill gaps in previous research.

Summary: The age-related cognitive decline that occurs in neurodegenerative diseases, including Alzheimer's disease (AD), is worsened. It is unclear whether age-related cognitive regulators in AD contribute to life span. The study reveals that C/EBP beta mediates longevity in a gene dose-dependent manner by activating AEP. It selectively triggers inhibitory GABAnergic neuronal degeneration, leading to abnormal neural excitation and cognitive dysfunction.

Summary: The dynamics of predator-prey interactions involving ostracod prey have been studied across the Cretaceous-Palaeogene extinction event. The study analyzed ostracod specimens from a section in eastern Brazil and found that predation intensity was lower during the Maastrichtian period compared to the Danian period. However, there was no drilling intensity observed in assemblages immediately above the K-Pg boundary, possibly due to abrupt environmental changes caused by the extinction event. The study also revealed variations in predation intensities between species and identified significant prey preference and avoidance behaviors during the Danian period.

Summary: Framing geoheritage thematically is important to reveal its diversity. Field investigations in the western part of the Greater Caucasus orogen have allowed for the characterization of three localities representing palaeoislands of the Caucasian Sea, which evolved as a semi-enclosed, marginal palaeosea during the Mesozoic. These localities are interpreted as geoheritage points, which are parts of larger geosites. Thematic geoheritage sites reflecting the existence of palaeoislands in all Mesozoic periods are essential for the understanding of the evolution of the Caucasian Sea during this era.

Summary: This paper proposes a new approach for the easy and quick assessment of geosite-focused web-pages based on scoring criteria reflecting the quality and quantity of geological information. The approach considers simplicity and correctness of information, technical properties, relative and absolute amounts of information, and accessibility for persons with disabilities. Testing the approach on three well-known geosites reveals deficiencies in the web-pages' promotional capabilities and errors in geological information. The approach shows promise in improving geosite promotion and recommends cooperation between the tourism industry and geological faculty members to create more informative web-pages.

Summary: Geoheritage plays a significant role in geoscience education at universities. This study evaluates the educational potential of two textbook localities, namely the Abmorghan anticline and the Skala monocline. Both sites offer opportunities for training students' skills and challenging their geological thinking. The evaluation shows that the educational potential of the Abmorghan anticline is advanced, while that of the Skala monocline is moderate. Universities can make use of these potentials, but attention should also be given to other geoheritage sites and marketing efforts.

Summary: This study determines the Fe-Mn interdiffusion rates in natural Mn-bearing garnet crystals with 750 ppm H2O using an experimental approach. The results show that the Fe-Mn interdiffusion coefficient slightly decreases with increasing Fe content, and water significantly enhances the Fe-Mn interdiffusion in garnet. These findings suggest that the time required for homogenization of the compositional zoning of a garnet is much shorter than previously thought.

Summary: The early Archean oceans underwent significant redox changes that had a lasting impact on the Earth's biosphere. This study investigates the geochemical characteristics of Archean Mnformations in southern India and reveals the importance of these sedimentary deposits in understanding the ancient redox conditions and sedimentation patterns. The findings suggest that the sediments were deposited in shallow to deeper shelf environments in the Archean proto-ocean, and they provide evidence of regional episodes of ocean oxygenation prior to the Great Oxygenation Event.
