Unlocking paleo-environmental information from Early Cretaceous shelf sediments in the Helvetic Alps: stratigraphy is the key! [PDF]
The northern alpine Helvetic thrust-and-fold belt includes an Early Cretaceous shallow-water carbonate succession, which was part of an extensive carbonate platform rimming the northern Tethyan margin.

Early Cretaceous (Valanginian) sea lilies (Echinodermata, Crinoidea) from Poland
Valanginian strata in central epicratonic Poland have recently yielded crinoids, not previously recorded from the area. The fauna comprises isocrinids (Balanocrinus subteres, B. gillieroni, “Isocrinus?” lissajouxi), millericrinids (Apiocrinites sp.) and comatulids (Comatulida indet.).

A Neoselachian shark from the non-marine Wessex Formation (Wealden Group: early Cretaceous, Barremian) of the Isle of Wight, southern England [PDF]
Bulk screening of Early Cretaceous (Barremian) Wessex Formation strata exposed on the south-east coast of the Isle of Wight, southern England, has resulted in the recovery of neoselachian shark teeth referred to the scyliorhinid Palaeoscyllium. These are

LATE BERRIASIAN–EARLY VALANGINIAN EVOLUTION AND DROWNING OF THE GETIC CARBONATE PLATFORM (SE SERBIA)
The Early Cretaceous was a time of significant development of carbonate platforms on the margins of the Tethys Ocean, including the Getic Carbonate Platform, in the northern peri-Tethys realm, cropping out in the Southern Carpathians (Romania) and ...
