FIRST EVIDENCE OF LOST‐WAX CASTING IN THE EARLIER BRONZE AGE OF SOUTH‐EASTERN SPAIN: THE SILVER BANGLE FROM EL ARGAR, GRAVE 292

open access: yesOxford Journal of Archaeology, Volume 45, Issue 1, Page 50-67, February 2026.
Summary In 1884, one of the burials discovered at El Argar, the eponymous site of the El Argar culture, revealed the remains of a woman wearing an unusual silver bangle. This ornament appears to be the first evidence of a silver object produced by lost‐wax casting in Bronze Age Iberia and, to date, in Western Europe.

Extreme Potomac Floods at Washington D.C. During the Past 500 Years

open access: yesGeophysical Research Letters, Volume 53, Issue 2, 28 January 2026.
Abstract Washington D.C. faces one of the highest 100‐year flood risks of any major city along the U.S. East Coast. In addition to storm‐surge inundation during hurricanes and nor'easters, water‐level observations for Washington are strongly skewed by major floods on the Potomac River.

Norian sponge and coral biostromes in the Antimonio Formation, northwestem Sonora, Mexico

open access: yesRevista Mexicana de Ciencias Geológicas, 2018
A diverse marine invertebrate fauna has previously been documented from the Norian carbonate interval of the Antimonio terrane. However, little research has been aimed at understanding its paleoecology, fine scale stratigraphy, and depositional ...

The role of glacial cycles in promoting genetic diversity in the Neotropics: the case of cloud forests during the Last Glacial Maximum

open access: yesEcology and Evolution, 2013
The increasing aridity during the Last Glacial Maximum (LGM) has been proposed as a major factor affecting Neotropical species. The character and intensity of this change, however, remains the subject of ongoing debate.

Early Archean stromatolites: Paleoenvironmental setting and controls on formation [PDF]

open access: yes
The earliest record of terrestrial life is contained in thin, silicified sedimentary layers within enormously thick, predominantly volcanic sequences in South Africa and Western Australia.

Isothermal Thermoluminescence Dating of Coral Reef Calcite: Implications for Sea‐Level Change

open access: yesGeophysical Research Letters, Volume 53, Issue 2, 28 January 2026.
Abstract Reconstructing past sea‐level changes is critical in Quaternary science. On remote oceanic reefs, aragonite‐to‐calcite alteration occurs during subaerial exposure, directly recording the timing of sea‐level fall. U–Th dating of coral calcite is challenging due to open‐system issues.

Morphology and paleoecology of a hybodontiform with serrated teeth, Priohybodus arambourgi, from the Late Jurassic of northeastern Brazil

open access: yesThe Anatomical Record, Volume 309, Issue 1, Page 5-32, January 2026.
Abstract Hybodontiformes was a diverse, successful, and important group of shark‐like chondrichthyans known from a variety of ecosystems. Some representatives of the order had a wide palaeogeographic distribution, as is the case with Priohybodus arambourgi. With a multicuspidate crown, P. arambourgi was the first hybodontiform to develop fully serrated

The “regime shift extinctions” hypothesis and mass extinction of waterbirds in Hawaiʻi

open access: yesEcosphere, Volume 17, Issue 1, January 2026.
Abstract Studies of biodiversity loss commonly imply that species extinctions occurred as a direct result of initial human arrival and thus are attributable to stewardship failures of Indigenous Peoples. However, recent studies have suggested this assumption is not supported by the evidence, prompting a global reevaluation of existing assumptions.

Size differences of Arctic marine protists between two climate periods—using the paleoecological record to assess the importance of within‐species trait variation

open access: yesEcology and Evolution, 2017
Mean body size decreases with increasing temperature in a variety of organisms. This size–temperature relationship has generally been tested through space but rarely through time.
