The biostratigraphy of platform carbonates and adjacent basins outcropping in the Prebetic Zone of Alicante, south-eastern Spain, is presented. With this aim, 42 sections from 13 major outcrops, of Aptian–Middle Cenomanian age, were analysed. Ten biostratigraphic units based upon benthonic foraminifers have been distinguished within this interval. Comparison with other previously published bioz...

Early Cretaceous body and trace fossils in Victoria, Australia, establish the oldest known presence of parastacid crayfish (Decapoda: Astacidea, Parastacoidea) in freshwater environments of Australia, and the oldest known crayfish in Gondwana. Parastacid body fossils, comprised of a partial abdomen (Palaeoechinastacus australianus, gen. et sp. nov.) and two chelae, are from a fluvial deposit in...

The record of Gondwanan Mesozoic lizards is very poor. Among the few species described for this region there is Tijubina pontei, an Early Cretaceous lizard from the Crato Formation (late Aptian) of northeast Brazil. Its description is very brief and lacks most of its diagnostic characters and clear delimitation from other lizard species. Here, a full redescription of the holotype is provided. T...

The Aptian Jiufotang Formation of northeast China is a Konservat Lagerstätte particularly rich in pterosaurs, notably azhdarchoids. Here we describe a new genus and species of toothed pteranodontoid pterosaur, Ikrandraco avatar gen. et sp. nov., based on two laterally flattened specimens. Ikrandraco avatar is diagnosed by a suite of features, including a very low and elongate skull, strongly in...

The fossil record of the turtle clade Baenidae ranges from the Early Cretaceous (Aptian–Albian) to the Eocene. The group is present throughout North America during the Early Cretaceous, but is restricted to the western portions of the continents in the Late Cretaceous and Paleogene. No credible remains of the clade have been reported outside of North America to date. Baenids were warmadapted fr...

The historical view of a uniformly warm Cretaceous is being increasingly challenged by the accumulation of new data hinting at the possibility of glacial events, even during the Cenomanian-Turonian (∼95 Myr ago), the warmest interval of the Cretaceous. Here we show that the palaeogeography typifying the Cenomanian-Turonian renders the Earth System resilient to glaciation with no perennial ice a...
