Ray-finned fishes (Actinopterigii) pycnodontiformes compounds a specialized group, small to medium-sized, with laterally compressed body and a batteries of flattened, peg-like teeth on the vomer, adapted for feeding on hard-shelled prey and by its life in near shore environments and/or characterized by reefs. Here is presented their first record to the carbonate deposits included in Estiva Formation, Maracaípe region, in the south of coastal Pernambuco Basin, considered Cenomanian-Turonian in age, where is also the first evidence of vertebrate rests. The record of fish remains open new perspective to this stratigraphic unit and to the basin in general, until the moment poorly known.
