Changes in land‐snail communities and steppe environments in the lower Rhône valley during the Lateglacial–Holocene transition

Boreas, EarlyView.
Land snail successions in the lower Rhône valley allow us to reconstruct the postglacial recolonization. From the Lateglacial period onwards, Mediterranean steppe communities appeared. The arrival of forest taxa was significantly delayed by aridity. The question of glacial refugia, both local and distant, primarily concerned Mediterranean species of ...

THE PALYNOLOGY CONTRIBUTION IN PALAEOENVIRONMENT INVESTIGATION. A CASE-STUDY OF A LATEGLACIAL-HOLOCENE SEDIMENTARY SEQUENCE NEAR BOLOGNA (NORTHERN ITALY)

EQA, 2017
The palynological studies are extremely relevant in the investigation of the evolution of palaeoenvironments. A case of pedopalynological studies was applied to the Lateglacial to Holocene sedimentary sequence derived from a small site located in San ...

Recognition of fossil keratose sponges in carbonates using petrographic and machine‐learning classification

Sedimentology, EarlyView.
ABSTRACT Filamentous, anastomosing spar‐filled networks in Phanerozoic carbonates have been interpreted as the mineralised remains of keratose (non‐spiculate) sponges, yet their recognition remains contested because fabrics of broadly similar appearance may arise from microbial, diagenetic or physical processes. This study combines direct fossil–modern

Palaeoenvironments at Sehonghong, Lesotho

, 2013
This thesis presents palaeoenvironmental analyses of material from Sehonghong rockshelter, a Middle and Later Stone Age site in the highlands of Lesotho. Stable carbon isotope analyses of late Pleistocene and Holocene sediments and faunal enamel allow for an assessment of altitudinal shifts of C3 and C4 grasslands with changing temperature.

Outcrop and subsurface characterisation of a mixed tidal and wave‐influenced coastline (Triassic Red Beds, SE Spain)

Sedimentology, EarlyView.
ABSTRACT Paralic depositional systems are complex and heterogeneous sedimentary environments, presenting challenges for predicting reservoir architecture and connectivity. Their stratigraphic and facies variability arises from the dynamic interplay between fluvial, tidal and wave processes, and their sensitivity to sea‐level fluctuations, sediment ...

Early Pliocene Varanus (Squamata, Varanidae) remains from Megalo Emvolon, Thessaloniki, Greece

The Anatomical Record, Volume 309, Issue 8, Page 2100-2123, August 2026.
The article describes new cranial and postcranial varanid material from Megalo Emvolon Lower Pliocene vertebrate fossil site near Thessaloniki. The fossils, likely representing a single individual, are referred to Varanus cf. marathonensis. Abstract This study describes new fossil varanid material from a recently discovered fossil spot (MVL site) at ...

Palaeoenvironments and elemental geochemistry across the Permian–Triassic boundary at Ursula Creek, British Columbia, Canada, and a comparison with some other deep‐water Permian–Triassic boundary shelf/slope sections in western North America

The Depositional Record, 2022
The Permian–Triassic boundary sediments at Ursula Creek accumulated in a continental shelf basin, or on the continental slope of the western Canadian passive margin, at 30°N palaeolatitude along the eastern Panthalassic Ocean margin.

Hydraulic reconstruction of catastrophic drainage from the Late Glacial, Lake Fraser, British Columbia, Canada

Journal of Quaternary Science, Volume 41, Issue 6, Page 873-887, August 2026.
ABSTRACT Glacial Lake Fraser, which formed in British Columbia against the retreating Cordilleran Ice Sheet, stored ~520 km3 of water before its near‐total drainage into the Salish Sea during an outburst flood event. Despite the impact of the outburst flood on sediment transport and landscape evolution in the Fraser River valley, its peak discharge and

Columnanidus calitzdorpensis ichnogen. ichnosp. nov: A new Middle Pleistocene subterranean termite trace fossil from South Africa

Journal of Quaternary Science, Volume 41, Issue 6, Page 933-949, August 2026.
ABSTRACT Termites are landscape geo‐engineers whose nesting activities substantially modify the physical and chemical properties of soils. Fossilised termite nests commonly constitute the only identifiable evidence of ancient termite activity and represent valuable trace fossil archives for reconstructing past environments.
