  abstract = {{T}he evolution of crocodylians as sea dwellers remains obscure because living representatives are basically freshwater inhabitants and fossil evidence lacks crucial aspects about crocodylian occupation of marine ecosystems. {N}ew fossils from marine deposits of {P}eru reveal that crocodylians were habitual coastal residents of the southeastern {P}acific ({SEP}) for approximately 14 million years within the {M}iocene (ca 19 to 5 {M}a), an epoch including the highest global peak of marine crocodylian diversity. {T}he assemblage of the {SEP} comprised two long and slender-snouted (longirostrine) taxa of the {G}avialidae: the giant {P}iscogavialis and a new early diverging species, {S}acacosuchus cordovai. {A}lthough living gavialids ({G}avialis and {T}omistoma) are freshwater forms, this remarkable fossil record and a suite of evolutionary morphological analyses reveal that the whole evolution of marine crocodylians pertained to the gavialids and their stem relatives ({G}avialoidea). {T}his adaptive radiation produced two longirostrine ecomorphs with dissimilar trophic roles in seawaters and involved multiple transmarine dispersals to {S}outh {A}merica and most landmasses. {M}arine gavialoids were shallow sea dwellers, and their {C}enozoic diversification was influenced by the availability of coastal habitats. {S}oon after the richness peak of the {M}iocene, gavialoid crocodylians disappeared from the sea, probably as part of the marine megafauna extinction of the {P}liocene.},
