Cenomanian genera

Xiphactinus (from Latin and Greek for "sword-ray") is an extinct genus of large predatory marine ray-finned fish that lived during the late Albian to the late Maastrichtian. The genus grew up to in length, and superficially resembled a gargantuan, fanged tarpon. It is a member of the extinct order Ichthyodectiformes, which represent close relatives of modern teleosts.

Kaprosuchus is an extinct genus of mahajangasuchid crocodyliform. It is known from a single nearly complete skull collected from the Upper Cretaceous Echkar Formation of Niger. The name means "boar crocodile" from the Greek , kapros ("boar") and , soukhos ("crocodile") in reference to its unusually large caniniform teeth which resemble those of a boar. It has been nicknamed "BoarCroc" by Paul Sereno and Hans Larsson, who first described the genus in a monograph published in ZooKeys in 2009 along with other Saharan crocodyliforms such as Anatosuchus and Laganosuchus. The type species is K. saha

Thalassomedon (from Greek, thalassa, "sea" and Greek, medon, "lord" or "ruler", meaning "sea lord") is a genus of plesiosaur, named by Welles in 1943.

Gobiconodon is an extinct genus of carnivorous mammals (or possibly non-mammalian mammaliaforms) belonging to the family Gobiconodontidae. Undisputed records of Gobiconodon are restricted to the Early Cretaceous of Asia and North America, but isolated teeth attributed to the genus have also been described from formations in England and Morocco dating as far back as the Middle Jurassic. Species of Gobiconodon varied considerably in size, with G. ostromi, one of the larger species, being around the size of a modern Virginia opossum. Like other gobiconodontids, it possessed several speciations to

Inoceramus (Greek: translation "fibrous shell" for the fibrous structure of the mineral crystals in the shell) is an extinct genus of fossil marine pteriomorphian bivalves that superficially resembled the related winged pearly oysters of the extant genus Pteria. They lived from the Early Jurassic to latest Cretaceous.

Stomatosuchus (meaning "mouth crocodile") is an extinct stomatosuchid neosuchian from the Late Cretaceous (Cenomanian) Bahariya Formation of Egypt. The type and only species is S. inermis. Much of what is known about Stomatosuchus has been inferred from the related genus Laganosuchus.

Oculudentavis is an extinct genus of lizard of uncertain taxonomic placement, originally but inaccurately identified as an avialan dinosaur (bird, in the broad sense). It contains two known species, O. khaungraae and O. naga. Each species is known from one partial fossil specimen in Burmese amber, which differ in several proportions. Their skulls measure in length, indicating that Oculudentavis would have been comparable in size with the modern bee hummingbird if it were an avialan. Both specimens were retrieved from 99-million-year-old deposits of the Hukawng Basin in Kachin State, northern M

Laganosuchus is an extinct genus of stomatosuchid crocodyliform. Fossils have been found from Niger and Morocco and date back to the Upper Cretaceous.

Alanqa is a genus of alanqid pterosaur from the Late Cretaceous period (Cenomanian stage) of what is now the Kem Kem Group of southeastern Morocco. The name Alanqa comes from the Arabic word العنقاء ''al-'Anqā''', for a mythical bird of Arabian culture.

Enchodus (from , 'spear' and 'tooth') is an extinct genus of aulopiform ray-finned fish related to lancetfish and lizardfish. Species of Enchodus flourished during the Late Cretaceous, where they were a widespread component of marine ecosystems worldwide, and there is some evidence that they may have survived to the Paleocene or Eocene; however, this may just represent reworked Cretaceous material.

Siroccopteryx is an extinct genus of anhanguerid pterodactyloid pterosaur which lived in Morocco during the Cenomanian stage of the Late Cretaceous. Some researchers, such as David M. Unwin, consider the genus a junior synonym of Coloborhynchus.

Elosuchus is an extinct genus of neosuchian crocodyliform that lived during the Middle Cretaceous of what is now Africa (Niger, Morocco, and Algeria).

Brachyphyllum (meaning "short leaf") is a form genus of fossil coniferous plant foliage. Plants of the genus have been variously assigned to several different conifer groups including Araucariaceae and Cheirolepidiaceae. They are known from around the globe from the Late Carboniferous to the Late Cretaceous periods.

Armigatus is an extinct genus of marine clupeomorph fishes belonging to the order Ellimmichthyiformes. These fishes lived in the Cretaceous (Albian to Campanian, about 103-72 million years ago); their fossil remains have been found in Mexico, Europe, the Middle East and North Africa, suggesting the genus ranged across the Tethys Sea.

Lonchodraco is a genus of lonchodraconid pterodactyloid pterosaur from the Early and Late Cretaceous of southern England. The genus includes species that were previously assigned to other genera.

Baikuris is an extinct genus of ant in the Formicidae subfamily Sphecomyrminae, and is currently placed in the tribe Sphecomyrmini. The genus contains four described species: the type species Baikuris mandibularis, along with Baikuris casei, Baikuris maximus, Baikuris mirabilis, B. ocellantis.

Bawitius is an extinct genus of giant polypterid from the Upper Cretaceous (lower Cenomanian) Bahariya Formation of Egypt. The type species is B. bartheli, named as a species of Polypterus in 1984, and the genus etymology comes from Bawiti, the principal settlement of the Bahariya Oasis in Egypt. It is known from the holotype TU-B SFB 69 Vb 003 (= Bah 5/12-016): left ectopterygoid scales and some sparse scales.

Puzosia is a genus of desmoceratid ammonites, and the type genus for the Puzosiinae, which lived during the middle part of the Cretaceous, from early Aptian to Maastrichtian (125.5 to 70.6 Ma). Sepkoski defines the range from Albian to Santonian. The generic name comes from the Serbian words "Puž" (snail) and "oce/ose" (axis), gaining its name from the shell's snail-like appearance.

Atlanticopristis (meaning "Atlantic saw") is an extinct genus of sclerorhynchoid that lived during the Late Cretaceous (Cenomanian) of what is now the Northeast Region of Brazil, between 100.5 and 93.9 million years ago. It contains a single species, Atlanticopristis equatorialis, originally assigned to the closely related genus Onchopristis.

Leptostomia () is an extinct genus of pterosaur that lived during the Cenomanian and possibly Albian stages of the ?Early-Late Cretaceous period in what is now Morocco, North Africa. Leptostomia is known from only two isolated rostrum (beak) fragments. In 2021, paleontologist Roy E. Smith and colleagues named the type and only known species, Leptostomia begaaensis, based on these fossils. Leptostomia is a small pterosaur, with the complete skull length estimated between , making it much smaller than many contemporary pterosaurs. The beak of Leptostomia is remarkably long, narrow, and compresse

Chimerarachne is a genus of extinct arachnids, containing five known species. Fossils of Chimerarachne were discovered in Burmese amber from Myanmar which dates to the mid-Cretaceous, about 100 million years ago. It is thought to be closely related to spiders, but outside any living spider clade. The earliest spider fossils are from the Carboniferous, requiring at least a 170 myr ghost lineage with no fossil record. The size of the animal is quite small, being only in body length, with the tail being about in length. These fossils resemble spiders in having two of their key defining features:

Belonostomus (from , 'dart' and 'mouth') is a genus of prehistoric ray-finned fish that was described by Louis Agassiz in 1844. It is a member of the order Aspidorhynchiformes, a group of fish known for their distinctive elongated rostrums.

Libycosuchus is an extinct genus of North African crocodyliform possibly related to Notosuchus; it is part of the monotypic Libycosuchidae and Libycosuchinae. It was terrestrial, living approximately 95 million years ago in the Cenomanian stage of the Late Cretaceous. Fossil remains have been found in the Bahariya Formation in Egypt, making it contemporaneous with the crocodilian Stomatosuchus, and dinosaurs, including the famous Spinosaurus.

Confractosuchus is a genus of extinct eusuchian crocodyliform from the Cretaceous Winton Formation of Australia. Described as a macro-generalist, Confractosuchus was found with the bones of a juvenile ornithopod dinosaur in its abdomen. It currently contains a single species, Confractosuchus sauroktonos, which literally means "broken dinosaur killer."

Corusichthys is an extinct marine pycnodontiform that lived during the Late Cretaceous of what is now Lebanon. It contains a single species, C. megacephalus from the late Cenomanian-aged Haqel site of the Sannine Formation.'''' left|thumb|Life restoration C. megacephalus is known from a 34 mm long fossil. It had plates arranged like a helmet around its head, and had a massive, triangular spine on its dorsal side. C. megacephalus is closely related the genera Trewavasia and Hensodon, as well as Coccodus''.

Araripichthys is an extinct genus of marine ray-finned fish that lived from the Aptian to Coniacian stages of the Cretaceous period. The genus is named after the Araripe Basin, where it was found in the Crato and Santana Formations. Other fossils of the genus have been found at Goulmima in Morocco, the Tlayua Formation of Mexico and the Apón Formation of Venezuela.

Coccodus is an extinct genus of marine pycnodontid fish that lived during the Late Cretaceous. The various species had a pair of massive, curved spines emanating from the lower sides of the head, and one curved spine on the top of its head. Unlike most pycnodontids (which tend to have short, marine butterflyfish-like bodies), Coccodus species had a comparatively long body, giving the living animals a superficial resemblance to a scaly chimaera.

Anagaudryceras is an extinct genus of ammonite from the later Cretaceous belonging to the Ammonoidea family Gaudryceratidae. Anagaudryceras has a moderately involute shell with a deep umbilicus and strongly ribbed outer whorl. Ribs are thick and rounded and cross over the venter uninterrupted.

Aipichthys is an extinct genus of bony fish that is possibly polyphyletic. Formerly classified in the Polymixiiformes, it is now thought to be a distant relative of oarfish and opahs.

Carpopenaeus is an extinct genus of prawn, which existed during the Upper Jurassic and Cretaceous periods. It contains three species.

Saratovia is a genus of targaryendraconian pterosaurs that lived during the Late Cretaceous in what is now Russia. The genus contains a single species, S. glickmani, known from a partial lower jawbone, and is named after the city of Saratov, where the specimen was found, and its discover Leonid S. Glickman. The fossil comes from sedimentary rocks of the Melovatka Formation. Uncovered in the 1940s, the only specimen was assigned to various genera such as Ornithocheirus, Anhanguera and Coloborhynchus before being recognized as a new taxon and named in 2025. Likewise, though long thought to belon
