Systematic utility of the phytosaur post‐dentary mandibular region

open access: yesPapers 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.

Early Jurassic foraminiferal assemblages in platform carbonates of Mt. Krim, central Slovenia

open access: yesGeologija, 2017
During the Early Jurassic, the subtropical carbonate platforms of the peri-Tethys Ocean experienced signifiant changes in their architectures, as well as in their biota compositions.

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

open access: yesGeochemistry, 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.

LicenseCalpionellid biostratigraphy and sedimentation of the Biancone limestone from the Rudnica Anticline (Sava Folds, eastern Slovenia)

open access: yesGeologija, 2019
Mt Rudnica in eastern Slovenia structurally belongs to the Sava Folds. The mountain itself is an exposure of the Mesozoic core of the Rudnica Anticline.

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

open access: yesBasin 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 ...

Correlation and biostratigraphy of the Kortrijk (Sint-Antonius) and Kortrijk (Lust) boreholes (early Silurian, Belgium)

open access: yesCarnets de Géologie, 2005
Since their drilling, respectively in 1961 and 1971, the 83W421 Kortrijk (Sint-Antonius) and 83W44 Kortrijk (Lust brewery) boreholes have been studied rather extensively for biostratigraphical information.

Distephanopsis concavus Horvat: a revised silicoflgellate species from the Middle Miocene of the Central Paratethys

open access: yesGeologija, 2016
The silicoflgellate species Distephanopsis concavus Horvat is revised based on further research of the type material. This species is characterized by having a basal ring with strongly concave sides which reduce the basal ring area and by four symmetry

Jurassic tracks and HS2: a twenty‐first century journey

open access: yesGeology Today, Volume 41, Issue 6, Page 234-243, November/December 2025.
The biggest UK railway construction site since the nineteenth century has exposed a near‐complete time slice through the entire Jurassic succession of central England. This is yielding a wealth of stratigraphical, palaeobiological and palaeoenvironmental data that is otherwise generally poorly exposed at the present day.

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

open access: yes, 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.
