Evolution of the northern Tethyan Helvetic Platform during the late Berriasian and early Valanginian [PDF]
The Depositional Record, 2016 AbstractThe Early Cretaceous period is characterized by widespread carbonate production in tropical and subtropical epicontinental seas, which was modulated by changes in sea‐level, detrital and nutrient fluxes, and the global carbon cycle. As a result, carbonate platforms were sensitive recorders of environmental change, which often anticipated global

Sedimentology, EarlyView.ABSTRACT Shelf‐edge deltas are commonly interpreted to record basinward facies migration across uninterrupted, gently dipping shelf margins; however, examples from mixed siliciclastic‐carbonate margins reveal more complex depositional dynamics. Periods and areas of carbonate sedimentation within mixed siliciclastic‐carbonate margins can modify shelf ...

Mercury enrichment indicates volcanic triggering of Valanginian environmental change
Scientific Reports, 2017 AbstractThe Valanginian stage (Early Cretaceous) includes an episode of significant environmental changes, which are well defined by a positive δ13C excursion. This globally recorded excursion indicates important perturbations in the carbon cycle, which has tentatively been associated with a pulse in volcanic activity and the formation of the Paraná ...

Fish remains from the Lower Cretaceous (Valanginian-Hauterivian) of Hárskút (Hungary, Bakony Mts) [PDF]
, 2017 Lower Cretaceous (Valanginian-Hauterivian) fish remains, collected in the Közöskút Ravine (nearby Hárskút, Hungary) in the 1960s are detailed here. Although the material is poorly preserved, it is of great importance, because this geographical region and

Late Valanginian extinction and turnover of Tethyan brachiopods: A signal of the Weissert Event (Bakony Mountains, Hungary) [PDF]
, 2020 Brachiopods, together with ammonoids, were collected bed-by-bed from several Lower Cretaceous pelagic sections and localities in the Bakony Mountains (Transdanubian Range, Hungary), dated by detailed ammonoid and nannofossil biostratigraphy.

The sinemydid turtle Ordosemys from the Lower Cretaceous Mengyin Formation of Shandong, China and its implication for the age of the Luohandong Formation of the Ordos Basin [PDF]
PeerJ, 2019 Chronostratigraphic correlation of terrestrial Early Cretaceous biotas in China is highly problematic due to the lack of marine deposits, few absolute dates, and limited number of index fossils.
