The osteology of Gladiopycnodus karami gen. et sp. nov., of Monocerichthys scheuchzeri gen. et sp. nov. and of Rostropycnodus gayeti gen. et sp. nov., three new fossil fishes from the marine Cenomanian (Late Cretaceous) of Lebanon, is studied in detail. Some of their cranial characters and the presence of a postcoelomic bone clearly refer these fishes to the order Pycnodontiformes. However, they differ from all other described Pycnodontiformes by two important characters. Their snout is elongated as a rostrum, formed by the enlarged prefrontal and the toothless premaxilla, with this premaxilla sutured by its upper margin to the lower margin of the prefrontal. Their pectoral fin is replaced by a strong spine articulated with the cleithrum. These two apomorphies justify the erection of a new family, the Gladiopycnodontidae. The skull of Monocerichthys scheuchzeri sp. nov. does not differ greatly from a classical pycnodontiform skull and this species seems to be the more primitive member of this new family. Gladiopycnodus karami gen. et sp. nov. and Rostropycnodus gayeti gen. et sp. nov. are much more specialized. They share some apomorphies not present in Monocerichthys scheuchzeri gen. et sp. nov., i. e., an extremely long rostrum and an elongated first anal pterygiophore that sustains with the postcoelomic bone a strong and long anal spine. Gladiopycnodontidae fam. nov. and Coccodontidae share a series of apomorphies that justify the erection of a new superfamily, Coccodontoidea, grouping these two families.

The objective of this article is to describe the first record of a theropod carnivorous dinosaur from the Late Cretaceous of the Adamantina Formation (Bauru Group, Paraná Basin) in the south of the state of Goiás in the Midwest region of Brazil. The methodology of this work was based on a bibliographic survey about the characteristics of teeth of theropods and the geology of the region, in addition to the description and morphological comparisons. This specimen was found in a geodiversity site called Serra da Portaria, in the Paraúna State Park, municipality of Paraúna, where residuals from the Adamantina Formation is exposed. The specimen, a fragmentary tooth covered with iron oxide, but with a partially preserved crown, was assigned as a percentage to an undetermined theropod for having a labiolingually compressed crown and cross section. In addition to the Bauru Group in the state of Goiás, only remnants of sauropod herbivorous dinosaurs are known for the Adamantina and Marília formations, the tooth described here is the first osteological record of a theropod from the south of Goiás.
