New remains of Titanochelon richardi (Testudines, Testudinidae) from the Upper Miocene of the Vallès‐Penedès Basin: taxonomic and phylogenetic implications

Papers in Palaeontology, Volume 11, Issue 6, November/December 2025.
Abstract The alpha‐taxonomy of continental giant tortoises (Testudinidae, Titanochelon) from the European Neogene is far from settled, which has implications for inferring their phylogenetic relationships. The diagnosis of the type species (Titanochelon bolivari) is dubious because it considered Titanochelon richardi as a junior subjective synonym ...

Re‐evaluation of the Carboniferous tetrapod Asaphestera platyris with comments on the amniote fauna of the Joggins Formation, Canada

Papers in Palaeontology, Volume 11, Issue 6, November/December 2025.
Abstract ‘Microsaurs’ are problematic late Palaeozoic tetrapods that have been grouped with reptiles on the one hand, or regarded as close relatives of amniotes on the other. Early phylogenetic analyses that included broadly sampled tetrapod taxa placed ‘microsaurs’ as close relatives of amniotes. Several recent phylogenetic analyses have, by contrast,

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.

Transition Zones at the Changing Coastal Terrestrial‐Aquatic Interface

Journal of Geophysical Research: Biogeosciences, Volume 130, Issue 11, November 2025.
Abstract Coastal soils are a significant but highly uncertain component of global biogeochemical cycles. These systems experience spatial and temporal variability in biogeochemical processes, driven by marsh‐to‐upland gradients and hydrological fluctuations.

Fluvial Denitrification Rates in an Agricultural River and Its Tributary Vary Due To Size and Season

Journal of Geophysical Research: Biogeosciences, Volume 130, Issue 11, November 2025.
Abstract Anthropogenic impacts such as land use change are increasing dissolved nitrogen (N) loading to streams and rivers, degrading downstream water quality. Denitrification, where nitrate (NO3−‐N) is converted to dinitrogen gas (N2), serves as a permanent N sink.
