The Berriasian carbonate successions cropping out in the shallow-water platform of easternmost Prebetic Domain (SE Spain) involve reef-associated environments including a diverse epibiota with diceratid representatives unreported so far. Interpretation different sub-environments suggests proximal-distal shallow transect. In shallowest nearshore environment, high energy conditions are recorded, ...

A review of the type material crocodylomorph ichnotaxon Crocodylopodus meijidei Fuentes Vidarte and Meijide Calvo, 2001 from Berriasian Spain is carried out. The allows a better characterization this provides interesting new data on candidate trackmakers especially their locomotion. Three different size classes possibly related to ontogenetic states or sexual dimorphism same small- medium-sized...

Over the past decades, abundant and well-preserved vertebrate fossils, known as Urho Pterosaur Fauna, have been recovered from Lower Cretaceous Tugulu Group in Junggar Basin, Xinjiang, NW China. Excavated materials belong to pterosaur, plesiosaur, dinosaur, crocodylomorph, turtle taxa. As such, they provide key insights into evolutionary history of several critical groups Early Cretaceous. The ...

ABSTRACT The Jurassic to Cretaceous strata exposed in the Rollrock Section, Sverdrup Basin, Arctic Canada, represent one of northernmost continuous outcrops spanning this poorly understood transition. Oxfordian–Valanginian mudstones Section were deposited a shallow marine environment and, as such, provide ideal lithology investigate response high latitude dinoflagellate cyst populations frequen...
