Reconstructing paleo-trophic relationships on the Brazilian Romualdo Formation (Early Cretaceous) through mercury analysis in fossils

Mercury (Hg) biomagnification values tend to reflect relationships between species in the trophic web the larger the value, the higher their position in the web. Here we present the first attempt to reconstruct paleo-trophic linkages during the onset of the Romualdo Formation in the Araripe Basin (Northeastern Brazil), based on analyses of Hg ...
