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.",
