Taphonomy and ontogeny of the brachyuran crab Exucarcinus gonzagai, from the Lower Cretaceous (Aptian) Romualdo Formation, Araripe Basin, NE Brazil
Matos, Suzana Aparecida; Castilho, Antonio Leão ; ; ; ; ; ; Assine, Mario Luis ; Simões, Marcello Guimarães (Journal of South American Earth Sciences, 2021) [Artigo]
Brachyurans played important ecological and evolutionary roles in the marine benthic communities of the past and were the components of the Mesozoic Decapod Revolution. Therefore, the search for their fossil remains is ... -
Daily time series of groundwater recharge derived from temporal variation of water level
Teramoto, Elias Hideo; Crioni, Pedro Luiz Becaro ; Chang, Hung Kiang (Sustainable Water Resources Management, 2021) [Artigo]
The estimation of groundwater recharge volume is a crucial requirement for the management of subsurficial water resources. The implementation of monitoring of the water table in shallow aquifers allows the seasonal variation ... -
Sedimentary evolution of distributive fluvial systems within intraplate tectonic active basins: Case study of the Early Cretaceous Araripina Formation (Araripe Basin, NE Brazil)
