Summary: In this study, the researchers validated the use of the N-15/N-14 ratio of enameloid-bound organic matter as a trophic level proxy and used it to reconstruct the trophic level of the megatooth sharks. The results showed that the extinct shark species, Otodus megalodon, occupied a higher trophic level than any known marine species. The study also revealed a dietary shift in the sharks as they evolved towards larger body sizes.

Summary: This paper analyzes the diversification of the Neotropical mangrove flora in the Caribbean region from the Miocene to the present. A Neogene-Quaternary diversification trend has been identified, with an increase of 25 genera compared to the existing Paleogene representatives. The appearance of mangrove genera occurred mainly in the Miocene and Oligo-Miocene transition, contributing to the overall diversification pattern. The absence of regional extinctions since the Miocene suggests the persistence of mangrove diversity in the Caribbean.

Summary: This article presents a high-resolution lacustrine record from a western Mediterranean intramountain basin, providing detailed paleoclimatic information from the Late Miocene to the Early Pleistocene. The study reveals the influence of orbital forcing and global paleogeographic and climate change on regional paleoclimate, as well as the connection between continental climate and marine dynamics in southwestern Europe. It suggests that the closure of the Central Atlantic Seaway and changes in the Atlantic Meridional Overturning Circulation played a role in the regional climate variability.

Summary: A detailed palaeointensity study was conducted in Central Anatolia, Turkey, using the modified Thellier method. The study significantly increased the database of palaeomagnetic data for the Anatolian region, covering a time window back to approximately 6 Ma. The results also revealed the presence of the Brunhes and Matuyama Chrons, as well as high field strength in the Pleistocene.

Summary: Analysis of airborne radio-echo sounding data reveals an extensive subglacial valley network in northern Greenland that developed over multi-million-year timescales. The channel network has a paleo-fluvial origin with localized modification by glacial processes. The study shows that the valley network experienced two episodes of relative base level fall during the Neogene, which may have been induced by widespread uplift events in Greenland.

Summary: Eastern Anatolia is a tectonically active region where the collision between Arabian and Eurasian plates leads to widespread volcanism. The tectonic evolution of this area is still debated, and various geological and geophysical studies have been conducted to understand it. This paleomagnetic study focuses on identifying tectonic rotations in order to gain insight into the region's tectonic development through examining volcanic rocks.

Summary: This study investigates the genetic variation of a treefrog species in the Neotropics. The results show a significant phylogeographic break dating back to the Miocene, coinciding with the retraction of marine incursions in the Parana basin. The spatial pattern of genetic diversity is not related to geographical distance or environmental variables.

Summary: Utilizing a 10-million-year record of planktonic foraminifera, the study sheds light on the late Neogene to Quaternary faunal evolution and surface water changes in the Subantarctic Zone, highlighting high productive surface waters in the Indian Ocean and the evolution of deep dwelling faunas over time.

Summary: The study establishes a chronostratigraphic framework for the late Quaternary of southern Africa by integrating various proxy data and proposing successive chronostratigraphic time periods. By conducting wiggle-matching between long and continuous records from different regions and integrating different data types, the research identifies distinct chronostratigraphic units for the late Quaternary in southern Africa.

Summary: A new genus, Patagorbitestella, is proposed in this study, which includes two extant species and one fossil species. The distinctive microscopic spiral threads on the protoconch and unique shell characters serve as diagnostic features for this new genus. This is the first record of Orbitestellidae in South America, indicating that Patagorbitestella has inhabited the Magellanic Region since at least the early Miocene.

Summary: Using a dense grid of 2D seismic data and exploration wellbores, the Neogene-Quaternary development of the mid-Norwegian and Lofoten-Vesteralen continental margin was reconstructed. The study revealed the formation of widespread ocean current-controlled contourite drifts along the entire margin segment, as well as the occurrence of inner shelf progradation and grounded ice sheets bringing large sediment volumes to the shelf. The study highlights the variability in continental margin growth and emphasizes the importance of erosion and deposition in source-to-sink systems.

Summary: This paper proposes a novel sparse representation based hierarchical evolutionary framework for classifying human activities, using data from sensors such as accelerometers and gyroscopes. The framework operates at multiple levels in the hierarchy and achieves high recognition results through novel algorithms and optimization techniques.

Summary: This paper presents a new method for automatically generating realistic geological and parameter models in Quaternary formations when modeling groundwater systems. The approach, utilizing the ArchPy Python module, operates in a hierarchical manner and streamlines the modeling process by automatically simulating stratigraphic unit boundaries, filling lithologies, and simulating petrophysical properties inside lithologies. The automation provides a flexible framework for generating stochastic models end-to-end and allows for uncertainty quantification at any level.

Summary: Chronostratigraphic records in the drylands of north China provide important archives to reveal the dynamic connections between climate changes and aeolian system behavior. This study investigates aeolian sediment accumulation around the Tengger Desert during the late Quaternary, showing control by multiple factors such as wind, aridity, sediment availability, and preservation capacity. The importance of sampling at multiple sites and the synchronous accumulation of aeolian sand and sandy loess at certain periods are emphasized.
