Abstract
From the shrimp fauna survey of the upper Aptian–lower Albian Romualdo Formation of the Araripe Basin, State of Pernambuco, Brazil, new records of the sergestid Paleomattea deliciosa Maisey & Carvalho, 1995, have been identified, in addition to description of the Cretainermis pernambucensis gen. et sp. nov. (Penaeoidea). The new fossil is characterized by the short, spiniform and toothless rostrum and well-marked cervical groove. These fossils form associations that differ taphonomically in two types: Type 1 association occurs in shale layers and it is represented by shrimp buried in situ. Type 2 association occurs in layers of calcareous sandstone with shrimps both buried in situ and transported.
