Paleoceanographic changes during the early Cretaceous (Valanginian-Hauterivian): evidence from oxygen and carbon stable isotopes

, 2000
We investigated Valanginian-Hauterivian bulk rock and belemnite samples from Vocontian Basin sections in southeastern France for their stable carbon and oxygen isotope signature.

Upper Hauterivian-upper Barremian planktonic foraminiferal assemblages from the Arroyo Gilico section (southern Spain)

, 2018
Late Hauterivian-earliest late Barremian planktonic foraminifera from the Arroyo Gilico section (Subbetic domain, Betic Cordillera) have been investigated to correlate their distribution to ammonite zonation and calcareous nannofossil bioevents. The 72-m-

Upper Valanginian to Lower Hauterivian coral faunas from the Sierra Larga (Prebetic zone, SE Spain)

, 2019
From the Upper Valanginian and Lower Hauterivian of the Sierra Larga (Prebetic zone, SE Spain) two small faunas of colonial corals are taxonomically described. The Valanginian fauna encompasses 23 species and the Hauterivian fauna 11 species.

A revision of the Lower Cretaceous foraminiferal genus Falsogaudryinella from northwest Europe and Romania, and its relationship to Uvigerinammina [PDF]

, 1995
We emend the definition of the foraminiferal genus Falsogaudryinella Bartenstein, 1977 based on observations of the type species, F. tealbyensis from the Barremian Lower Tealby Clay of Lincolnshire, U.K.

Palaeotemperatures, polar ice-volume, and isotope stratigraphy (Mg/Ca, delta 18O, delta 13C, 87Sr/86Sr) : the Early Cretaceous (Berriasian, Valanginian, Hauterivian)

, 2007
Temporal trends through Early Cretaceous time of δ13C, δ18O, Mg/Ca, and 87Sr/86Sr in calcite, and δ18O in seawater, are discussed using belemnites from SE France and SE Spain.

Turtles from the Early Cretaceous (Hauterivian-Barremian) of La Rioja (Cameros Basin, Spain)

, 2010
The information about the turtles from the Early Cretaceous of the Iberian Peninsula is, until now, very poor. We describe here three specimens found in the Lower Cretaceous (Hauterivian-Barremian) of La Rioja, of at least two different taxa, being one ...

Early cretaceous (Valanginian and Hauterivian) belemnites and organic-walled dinoflagellate cysts from a marine hydrothermal vent site and adjacent facies of the Mecsek Mts., Hungary

, 2013
The first record of belemnites from fossil hydrothermal vent sites in the Mecsek Mountains of Hungary emphasizes the occurrences of belemnites in Mesozoic chemosynthetic-microbial based ecosystems reported only from cold seep carbonates to date. From the
