Trace fossils from Serpukhovian (Mississipian) sediments of Mospanivska geological structure (Dniper-Donetsk depression)

Вісник Харківського національного університету імені В.Н. Каразіна. Серія Геологія. Географія. Екологія
Introduction. Exhaustion of large oil and gas deposits leads to exploring smaller geological structures, from which large amount of core cannot be extracted.

The Variable Impact of Heinrich Events on the Benthic Environment of the Porcupine Abyssal Plain

Paleoceanography and Paleoclimatology, Volume 41, Issue 5, May 2026.
Abstract Heinrich events (HEs) are Pleistocene climate disturbances caused by massive freshwater discharges from the Laurentide Ice Sheet via the Hudson Strait. They appear in marine sediments as layers of ice‐rafted detritus (IRD) and significantly impact the benthic environment.

Seismic Stratigraphy and Tectonic Evolution of the Forearc Georgia Basin (Upper Cretaceous–Miocene), Canada and USA, With Implications for CO2 Sequestration

Basin Research, Volume 38, Issue 3, May–June 2026.
2D seismic and well data reveal multi‐phase basin filling in the Whatcom Sub‐Basin shaped by syn‐depositional tectonism. An Eocene transition from forearc basin to forearc depression corresponds to decreasing normal‐fault density and throw, both upsection and eastward. Paleogene–Neogene strata are the best CO2 storage targets.

Dinosaur footprints and other Ichnofauna from the Cretaceous Kem Kem Beds of Morocco [PDF]

, 2014
We describe an extensive ichnofossil assemblage from the likely Cenomanian-age 'lower' and 'upper' units of the 'Kem Kem beds' in southeastern Morocco.

‘Typical’ No More: Digital Re-Evaluation of Yanguoxia Caririchnium Trackways Reveals Behavioural Complexity

Geosciences
Ornithopod dinosaur trackways (OA and OB) from the Lower Cretaceous Hekou Group at Yanguoxia (Gansu Province, China) have previously been described as “typical”—a term applied to contrast them with swim traces from the same surface rather than as a ...

Selected Studies in Lower Paleozoic Ichnology

, 1979
Despite the attention recently given to ichnology, intensive investigations have been mounted in only a limited number of critical areas. These include the zoological affinities of, and the paleobathymetric significance of soft-sediment ichnofossils ...
