Comments on 'U-Pb dated flowstones restrict South African early hominin record to dry climate phases' (Pickering et al. Nature 2018;565:226–229)

South African Journal of Science, 2020
Pickering et al. (Nature 2018;565:226–229) utilised calcium carbonate flowstone deposits (i.e. speleothems) from eight Pliocene and Pleistocene South African Cradle of Humankind cave sites to propose that biases were created within the fossil record due ...

Sedimentary Architecture of the Stimson Formation at the Naukluft Plateau, Gale Crater, Mars

Journal of Geophysical Research: Planets, Volume 131, Issue 2, February 2026.
Abstract Sedimentary texture, facies, and architecture can be used to reconstruct the palaeoenvironment under which sediments accumulate. On Mars, palaeoenvironmental reconstructions are used to understand ancient Martian atmospheric circulation, surface sedimentary processes, and the presence of water, to provide insight into ancient habitability and ...

Diversity of Late Cenozoic Actinopterygian Assemblages of the South of Eastern Europe

Diversity
In the late Cenozoic, the south-west of Eastern Europe was a region affected by extensive hydrological transformations that resulted in the retreat of the Eastern Paratethys and the emergence and further evolution of freshwater communities.

New, large actinopterygian fishes from the upper Carboniferous of Nýřany, Czech Republic [PDF]

Acta Palaeontologica Polonica
The lacustrine coal deposits at Nýřany, Czech Republic, yielded a diversified vertebrate assemblage of the Middle Pennsylvanian (Moscovian) age, represented by the remains of early tetrapods, as well as numerous freshwater ichthyofauna, including ...

Integrating Aegean Last Interglacial faunas into the Mediterranean palaeobiogeographic framework: New evidence from Karpathos (Greece)

Journal of Quaternary Science, Volume 41, Issue 1, Page 80-98, January 2026.
ABSTRACT The Last Interglacial (LIG) or Marine Isotope Stage (MIS) 5e, spanning 129 to 116 kyrs ago, is recognised as one of the warmest periods in the Quaternary, with global sea surface temperatures (SSTs) 1°C–2°C higher than today, sea levels 5–10 m above the current level and biogeographical range expansion of specific tropical species into the ...

Subfossil Insects of the Kebezen Site (Altai Mountains): New Data on the Last Deglaciation Environment

Insects
This paper focuses on insect remains found at the Kebezen site (51.93600° N, 87.09665° E) on the Turachak stream, Altai Republic, Russia, in layers ranging in age from 20.1 to 19.3 cal ky BP, corresponding to the onset of the last deglaciation ...

Genesis and depositional environment of organic-rich sediments in the Neogene organic-rich sediments from the Aleksinac deposit (Serbia): Part B [PDF]

Oil Shale
To determine the characteristics of the palaeoenvironment that affected organic richness, the Neogene organic-rich sediments in the Upper layer of the Aleksinac deposit (Dubrava block, Serbia) were examined.

Minimally Destructive Radiocarbon Dating of Bone

Rapid Communications in Mass Spectrometry, Volume 40, Issue 9, 15 May 2026.
ABSTRACT Rationale Bone is commonly used in radiocarbon dating in archaeology and other disciplines. Despite advances in collagen extraction protocols, the process remains destructive, requiring sawing, drilling or crushing of bone material. While non‐destructive approaches have recently been applied in ancient genomics and palaeoproteomics, no ...

Freshwater amphibians and squamates from Villeveyrac (lower Campanian; Hérault, France): palaeodiversity, palaeoenvironment and implications for the Late Cretaceous palaeobiogeography of the European herpetofauna

Papers in Palaeontology, Volume 12, Issue 1, January/February 2026.
Abstract The Late Cretaceous witnessed numerous transgression–regression sequences and the onset of a global cooling phase at the start of the Campanian. In the European archipelago, these environmental changes, combined with active plate tectonics, facilitated the formation of ephemeral land bridges that served as dispersal routes for a variety of ...
