The fate of the homoctenids (Tentaculitoidea) during the Frasnian-Famennian mass extinction (Late Devonian) [PDF]

, 2006
The homoctenids (Tentaculitoidea) are small, conical-shelled marine animals which are amongst the most abundant and widespread of all Late Devonian fossils.

Systematic utility of the phytosaur post‐dentary mandibular region

Papers in Palaeontology, Volume 11, Issue 6, November/December 2025.
Abstract Phytosaurs, crocodile‐like archosaurs from the Late Triassic, are known for their unique skull shape, whereas their mandibles are poorly studied. Two‐dimensional (2D) geometric morphometric (GM) analysis is commonly used on dinosaurs and mammals.

Remagnetization of Lower Cretaceous Limestones in the Western Tethyan Himalaya and Its Tectonic Implications for the India‐Asia Collision

Geochemistry, Geophysics, Geosystems, Volume 26, Issue 11, November 2025.
Abstract The drift history of the Tethyan Himalaya provides key constraints on the India‐Asia collision, Himalayan‐Tibetan orogenesis, and associated global climate change. Here we present rock magnetic, petrographic, geochronologic, and paleomagnetic results of the Bolinxiala Formation limestones in the western Tethyan Himalaya.

Drainage Pattern Changes in Southeastern Tibet Inferred from Eocene–Modern Sediment Provenance of the Yanyuan Basin

Basin Research, Volume 37, Issue 6, November/December 2025.
Deep gorges with abrupt river elbows and high‐elevation, low‐relief interfluves containing fluvial sedimentary rocks characterize southeastern Tibet. This transient landscape reflects Eocene to present drainage divide migrations and river captures, reshaping catchment boundaries through episodic exchanges of drainage area between neighboring basins ...

Response and Recovery of the Comanche Carbonate Platform Surrounding Multiple Cretaceous Oceanic Anoxic Events, Northern Gulf of Mexico [PDF]

, 2015
The ubiquity of carbonate platforms throughout the Cretaceous Period is recognized as a product of high eustatic sea-level and a distinct climatic optimum induced by rapid sea-floor spreading and elevated levels of atmospheric carbon-dioxide.
