             abstract = "The lower Miocene Pirabas Formation in the North of Brazil was 
                         deposited under influence of the proto-Amazon River and is 
                         characterized by large changes in the ecological niches from the 
                         early Miocene onwards. To evaluate these ecological changes, the 
                         elasmobranch fauna of the fully marine, carbonate-rich beds was 
                         investigated. A diverse fauna with 24 taxa of sharks and rays was 
                         identified with the dominant groups being carcharhiniforms and 
                         myliobatiforms. This faunal composition is similar to other early 
                         Miocene assemblages from the proto-Carribbean bioprovince. 
                         However, the Pirabas Formation has unique features compared to the 
                         other localities; being the only Neogene fossil fish assemblage 
                         described from the Atlantic coast of Tropical Americas. Phosphate 
                         oxygen isotope composition of elasmobranch teeth served as proxies 
                         for paleotemperatures and paleoecology. The data are compatible 
                         with a predominantly tropical marine setting with recognized 
                         inshore and offshore habitats with some probable depth preferences 
                         (e.g., Aetomylaeus groups). Paleohabitat of taxa particularly 
                         found in the Neogene of the Americas (Carcharhinus ackermannii, 
                         Aetomylaeus cubensis) are estimated to have been principally 
                         coastal and shallow waters. Larger variation among the few 
                         analyzed modern selachians reflects a larger range for the 
                         isotopic composition of recent seawater compared to the early 
                         Miocene. This probably links to an increased influence of the 
                         Amazon River in the coastal regions during the Holocene.",
