, 2018 Most reports of Paleozoic and Mesozoic vertebrates from Venezuela are anecdotical, with few detailed descriptions of mostly ‘fish' groups. Synapsids (e.g., mammals) are totally unknown, and dinosaurs are only reported from the La Quinta Formation.Brinkmann, Winand, Lozsán, Roberto, Sánchez-Villagra, Marcelo +2 morecore Surface freshwater storage variations in the Orinoco floodplains using multi-satellite observations [PDF]
, 2014 Variations in surface water extent and storage are poorly characterized from regional to global scales. In this study, a multi-satellite approach is proposed to estimate the water stored in the floodplains of the Orinoco Basin at a monthly time-scale ...Calmant, Stéphane, Frappart, F., Leon, J.
