Resumen
The chondrichthyan fauna from the Pirabas Formation is redescribed.Only thirteen nominal taxa are considered valid. From these taxa, ten were reassigned to extant taxa (Carcharhinus sorrah, Carcharhinus perezii,Galeocerdo cuvier, Rhizoprionodon lalandii, Sphyrna sp., Hemipristis elongatus, Carcharodon carcharias, Isurus oxyrinchus, Nebrius ferrugineus, and indeterminate Myliobatidae), confirming the Neogene age of this formation. This elasmofauna is compared with other Caribbean and African Tertiary faunas. A fauna de Chondrichthyes da Formação Pirabas é redescrita no presente trabalho. Apenas treze taxa nominais são considerados como válidos.Desses taxa, dez foram considerados como ainda viventes (Carcharhinus sorrah, Carcharhinus perezii, Galeocerdo cuvier, Rhizoprionodon lalandii, Sphyrna sp., Hemipristis elongatus, Carcharodon carcharias, Isurus oxyrinchus, Nebrius ferrugineus, Myliobatidae), confirmando a idade Neogênica desta formação. Essa elasmofauna é comparada com as faunas do Terciário do Caribe e da África.
