Evolution of the East Antarctic Ice Sheet Since Glacial Inception From Seismic Stratigraphic Records in Vincennes Bay

Paleoceanography and Paleoclimatology, Volume 41, Issue 4, April 2026.
Abstract Seismic reflection data from Vincennes Bay, East Antarctica, provide the first insights into the Cenozoic evolution of the East Antarctic Ice Sheet (EAIS) in the Knox Coast. Long‐distance seismic horizon correlation allows age estimates for the seismic stratigraphic framework constructed for the continental shelf.

Depositional Facies, Sequence Stratigraphy, and Diagenesis of Lower Cretaceous Carbonate Reservoir, Southern Iraq: Implications for Petroleum Exploration

Journal of Petroleum Geology, Volume 49, Issue 2, Page 312-345, April 2026.
ABSTRACT The Lower Cretaceous Yamama Formation of southern Iraq represents a key carbonate reservoir within Iraq and the Middle East, yet its complex depositional facies architecture and diagenetic alterations present challenges for predicting reservoir quality.

Middle Triassic tetrapod footprints of southern South America

, 2004
In South America, tetrapod footprints of Middle Triassic age were only described from the Cuyana (Cerro de las Cabras Formation) and Ischigualasto-Villa Unión (Los Rastros Formation) basins in west-central Argentina. They are scarce and remain mostly undescribed.

The making of pure quartzose sand in continental interiors: Paraná River (Brazil and Argentina)

Sedimentology, Volume 73, Issue 3, Page 802-837, April 2026.
ABSTRACT As part of a comprehensive project on sedimentary processes in South America, this study focuses on sediment generation in the intracratonic Paraná Basin and monitors the evolution of sand composition along the Paraná River from central Brazil to the Río de la Plata estuary in Argentina.

Phylogenomics illuminates the complex evolutionary history of Bibionomorpha (Diptera)

Systematic Entomology, Volume 51, Issue 2, April‐June 2026.
Phylogenomics supports Bibionomorpha (Anisopodoidea, Bibionoidea, Scatopsoidea, Sciaroidea) as a sister to Brachycera, and Axymyiidae and Perissommatidae as a sister to Bibionomorpha + Brachycera. Phylogenetic network analysis tentatively suggests a possible reticulation leading to Bolitophilidae, and mitochondrial data support sex‐specific ...
