Supercritical‐flow structures in a Cretaceous submarine channel–lobe transition zone, Point Loma Formation, California

open access: yesThe Depositional Record, Volume 12, Issue 3, June 2026.
We document meter‐scale antidune and cyclic‐step deposits in channel–lobe transition zone (CLTZ) deposits of the Upper Cretaceous Point Loma Formation in San Diego, California. These results provide new insights into sediment transport dynamics in CLTZ environments, which are critical for understanding reservoir connectivity and heterogeneity in ...

Quantification of the Eocene–Oligocene transition in the Zagros Foreland Basin: Palaeogeographic control on sequence architecture and tectonic signal preservation

open access: yesThe Depositional Record, Volume 12, Issue 3, June 2026.
New bio‐sequence framework for the Eocene–Oligocene transition in Zagros. Geochemical data validate basin depth control on SB1 vs. SB2 boundaries. SEM‐EDS analyses confirm subaerial exposure versus continuous deposition. Sensitivity analysis quantifies sub‐10% uncertainty in stratigraphic interpretations. Resolves the Pyrenean orogeny's variable impact

Phylogenetic and Environmental Insights Into the Biogeography of the Western Blacknose Dace, Rhinichthys obtusus

open access: yesEcology and Evolution, Volume 16, Issue 6, June 2026.
Pleistocene glaciations have shaped freshwater fish evolution and distribution patterns across North America. This study investigated the phylogeographical history of the Western Blacknose Dace (Rhinichthys obtusus) using mitochondrial genomic data, revealing three major clades that diverged 2–1.5 million years ago during Pleistocene glaciations when ...
