Ctenopristis is a prehistoric genus of sawfish whose fossils are found in rocks dating from the Maastrichtian stage in Jordan. The anterior teeth of Ctenopristis have a high cusp compared to certain other ancient sawfish genera.

Ceramornis is a prehistoric bird genus from the Late Cretaceous. It lived shortly before the Cretaceous–Paleogene extinction event in the Maastrichtian, some 66 million years ago (mya). Its remains were found in the Lull 2 location, a Lance Formation site in Niobrara County, Wyoming. A single species is known, Ceramornis major, and even that only from a proximal piece of coracoid. This is specimen UCMP V53957, which was collected by a University of California team in 1958.
Congorhynchus is a genus of prehistoric ray-finned fish that was described by E. Darteville and E. Casier in 1949.
Gasteroclupea is a genus of prehistoric clupeiform fish that is related to modern anchovies and herrings. Its fossils date back to the Maastrichtian stage of the Late Cretaceous period. Fossils of the genus have been found in the Yacoraite Formation of Argentina and the El Molino Formation of Bolivia.
Coriops is a genus of prehistoric bony fish. Its fossils are found in Campanian, Maastrichtian, and possibly Paleocene age deposits. This chronological distribution means that the genus may have survived the Cretaceous–Paleogene extinction event that killed the dinosaurs.
Eodiaphyodus is a genus of Elopiformes fish that is classified in the suborder Albuloidea. It is related to the modern Tarpon. This fish lived in what is now Morocco during the Late Cretaceous Period. It crushed its food with bony plates found in the back of its throat.
Coupatezia is a prehistoric genus of ray in the family Dasyatidae whose fossils are found in strata dating from the Maastrichtian stage until the last species' extinction during the Middle Eocene. These rays were found shallow seas in Europe, Africa and the eastern United States.
Dalpiazia is an extinct genus of sclerorhynchid sawfish whose fossils are found in rocks dating from the Maastrichtian stage in mines in Jordan, Libya, Morocco and Syria. The type species D. stromeri was named by Checchia-Rispoli (1933) in honor of Ernst Stromer, and the holotype, a rostral tooth, was found in Tripolitania, Libya.
Igdabatis is a prehistoric genus of ray whose fossils are found in rocks dating from the Maastrichtian stage of Spain, the Dukamaje Formation of Niger and the Takli, Lameta, Fatehgarh and Intertrappean Beds Formations of India.
Pucabatis is a prehistoric genus of ray whose fossils are found in rocks dating from the Maastrichtian stage. The type and only species is P. hoffstetteri. Fossils of Pucabatis have been found in the El Molino Formation of Bolivia and the Bagua Formation of Peru.
Pucapristis is a prehistoric genus of sclerorhynchid ray whose fossils first appear in the fossil record in rocks dating from the Maastrichtian stage. The genus was described in 1963 by Schaeffer. Fossils of Pucapristis have not been found in any subsequent strata. Incidentally, the Maastrichtian is the final portion of the Cretaceous Period and its endpoint marks the advent of the Cretaceous–Paleogene extinction event. This major geological transition is famous for being the mass extinction that wiped out the dinosaurs.
Rhombodus is a prehistoric genus of ray belonging to the family Rhombodontidae.
Erquitaia is a poorly known genus of prehistoric galeomorph shark whose fossils are found in rocks dating from the Maastrichtian stage.
Phyllodus is an extinct genus of bony fish from the Maastrichtian to Middle Miocene. Fossils of the genus have been found in the Maastrichtian to Lancian Hell Creek Formation and the Eocene London Clay.
Mawsoniidae is an extinct family of prehistoric coelacanth fishes which lived during the Triassic to Cretaceous periods. Members of the family are distinguished from their sister group, the Latimeriidae by the presence of ossified ribs, a coarse rugose texture on the dermatocranium and cheek bones, the absence of the suboperculum and the spiracular, and reduction or loss of the descending process of the supratemporal. Mawsoniids are known from North America, Europe, South America, Africa, Madagascar and Asia. Unlike Latimeriidae, which are exclusively marine, Mawsoniidae were also native to freshwater and brackish environments. Mawsoniids represent among the youngest known coelacanths, with the youngest known remains of the freshwater genus Axelrodichthys from France and an indeterminate marine species from Morocco being from the final stage of the Cretaceous, the Maastrichtian, roughly equivalent in age to the youngest known fossils of latimeriids. Species of Mawsonia and Trachymetopon are known to have exceeded 5 metres in length, making them among the largest known bony fish to have ever existed.
Pseudoegertonia is an extinct genus of prehistoric bony fish that lived during the Maastrichtian age of the Cretaceous period and Danian age of the Paleocene epoch.
Goudkoffia is an extinct genus of prehistoric bony fish that lived during the Maastrichtian stage of the Late Cretaceous epoch.
Natlandia is an extinct genus of prehistoric bony fish that lived during the Maastrichtian stage of the Late Cretaceous epoch.
Socognathus is a genus of prehistoric chamopsiid polyglyphanodontian lizards containing species that lived from the Middle Campanian stage to the late Maastrichtian. Several specimens of the type species, Socognathus unicuspis, have been found in Alberta, Canada. A second species, Socognathus brachyodon is known from the late Maastrichtian Lance Formation; its fossils have been found in Wyoming, United States.
Sclerorhynchoidei is an extinct suborder of rajiform rays that had long rostra with large denticles similar to sawfishes and sawsharks. This feature was convergently evolved and their closest living relatives are actually skates. While they are often called "sawfishes", sawskates is a more accurate common name for sclerorhynchoids. The suborder contains five named families: Ganopristidae, Ischyrhizidae, Onchopristidae, Ptychotrygonidae, and Schizorhizidae. Several genera are not currently placed in any of these families. Sclerorhynchoids first appeared in the Barremian and went extinct during the Cretaceous–Paleogene extinction event, with former Paleocene occurrences being misidentifications or reworked specimens.
Kookne is a prehistoric bird genus from the Late Cretaceous. Known from a coracoid, the remains of the only known species Kookne yeutensis were found in rocks from the Late Cretaceous (Maastrichtian) Chorrillo Formation of Santa Cruz, Argentina.
