Cenomanian dinosaurs

Spinosaurus (; ) is a genus of large spinosaurid theropod dinosaurs that lived in what is now North Africa during the Cenomanian stage of the Late Cretaceous period, about 100 to 94 million years ago. The genus was known first from Egyptian remains discovered in 1912 and described by German palaeontologist Ernst Stromer in 1915. The original remains were destroyed in World War II, but additional material came to light in the early 21st century. It is unclear whether one or two species are represented in the fossils reported in the scientific literature. The type species, S. aegyptiacus, is mai

Carcharodontosaurus (; "shark-toothed lizard") is a genus of large theropod dinosaur that lived in Northwest Africa from about 100 to 94 million years ago during the Cenomanian stage of the Cretaceous. The taxon was first described in 1925 by French paleontologists Charles Depéret and Justin Savornin as Megalosaurus saharicus, based on two fossil teeth discovered in Algeria, which are now lost. A partial skeleton was discovered in Egypt as early as 1914 by crews of German paleontologist Ernst Stromer, although he did not report the find until 1931. Based on this specimen, together with the tee

Giganotosaurus ( ) is a genus of large theropod dinosaur that lived in what is now Argentina, during the early Cenomanian age of the Late Cretaceous period, approximately 99.6 to 95 million years ago. The holotype specimen was discovered in the Candeleros Formation of Patagonia in 1993 and is almost 70% complete. The animal was named Giganotosaurus carolinii in 1995; the genus name translates to "giant southern lizard", and the specific name honors the discoverer, Ruben Carolini. A dentary bone, a tooth, and some tracks, discovered before the holotype, were later assigned to this animal. The g

Buitreraptor (meaning "La Buitrera seizer") is a genus of unenlagiine theropod dinosaurs that lived during the Late Cretaceous of Argentina at the Candeleros Formation. Buitreraptor was described in 2005 and the type species is Buitreraptor gonzalezorum. It was rooster-sized and had a very elongated head with many small teeth.

Muttaburrasaurus was a genus of herbivorous iguanodontian ornithopod dinosaur that lived in what is now north-eastern Australia sometime between 112 and 103 million years ago during the early Cretaceous period. It has been recovered in some analyses as a member of the iguanodontian clade Rhabdodontomorpha, or alternately as a member of Elasmaria. After Kunbarrasaurus, it is Australia's most completely known dinosaur from skeletal remains. It was named after Muttaburra, the site in Queensland, Australia, where it was found. The dinosaur was selected from twelve candidates to become the official

Smith and colleagues in 2001. The genus contains a single species, Paralititan stromeri, named based on a fragmentary skeleton including vertebrae and limb bones. These fossils were unearthed by an American expedition to the Bahariya Oasis in western Egypt in rock layers of the Bahariya Formation. This formation dates to the Cenomanian stage of the Late Cretaceous, which lasted . An incomplete (back) vertebr

Rugops (meaning 'wrinkle face') is a monospecific genus of basal abelisaurid theropod dinosaur that lived during the Late Cretaceous period (Cenomanian stage, approximately 95 million years ago) in what is now the Echkar Formation in Niger. The type and only species, Rugops primus, is known only from a partial skull. It was named and described in 2004 by Paul Sereno, Jeffery Wilson and Jack Conrad. Rugops has an estimated length of and weight of . The top of its skull bears several pits which correlates with overlaying scale and the front of the snout would have had an armour-like dermis.

Australovenator (meaning "southern hunter") is a genus of megaraptoran theropod dinosaur from the Late Cretaceous Winton Formation (Cenomanian, 95 million years ago) of Australia. Some specimens from the Albian-aged Eumeralla Formation and the Wonthaggi Formation may belong to Australovenator. It is known from partial cranial and postcranial remains, which were described in 2009 by Scott Hocknull and colleagues, although additional descriptions and analyses continue to be published. It is the most complete predatory dinosaur discovered in Australia. It has been suggested that Australovenator i

The type specimen of Eolambia was discovered by Carole and Ramal Jones in 1993; the species name honors Carole. Since then, hundreds of bones have been discovered from both adults and juveniles, representing nearly every element of the skeleton. All of the specimens have thus far been found in Emery County, Utah, in a layer of rock known as the Mussentuchit Membe

Rebbachisaurus (meaning "Aït Rebbach lizard") is a genus of sauropod dinosaur that lived in what is now Africa during the Late Cretaceous period, between 99 and 97 million years ago. The only valid species is R. garasbae. However, two other species have been assigned to the genus; R. tessonei, now Limaysaurus tessonei, and the nomen dubium R. tamesnensis. Known from a single, incomplete skeleton, much of R. garasbae's anatomy is unknown. The skeleton, discovered in 1948, was unearthed in the Errachidia Province of Morocco from strata of the Kem Kem Beds.

It was described by American paleontologist Paul Sereno and colleagues in 1996. The genus contains a single species, D. agilis, named based on an incomplete postcranial skeleton, the holotype specimen. However, some fossils from the Bahariya Formation of Egypt that were formerly referred to the theropod Bahariasaurus have been suggested to belong to Deltadromeus. The holotype specimen of Deltadromeus was unearthed by a

Skorpiovenator ("scorpion hunter") is a genus of abelisaurid theropod dinosaur from the Late Cretaceous (Cenomanian to Turonian) Huincul Formation of Argentina. The sole species of Skorpiovenator, S. bustingorryi, was named in honour of Manuel Bustingorry, the late owner of the farm on which the type specimen was discovered.

A tibia fragment was assigned to Skorpiovenator in 2022.

Animantarx ( ; meaning 'living citadel') is a genus of nodosaurid ankylosaurian dinosaur from the Early and Late Cretaceous of western North America. Like other nodosaurs, it would have been a slow-moving quadrupedal herbivore covered in heavy armor scutes, but without a tail club. The skull measures approximately 25 cm (10 inches) in length, suggesting the animal as a whole was no more than 3 meters (10 feet) long.

Siats (/see-ats/) is an extinct genus of large theropod dinosaurs known from the Late Cretaceous Cedar Mountain Formation (Mussentuchit Member) of Utah, United States. The genus contains a single species, Siats meekerorum. It was initially classified as a megaraptoran, a clade of large theropods with controversial relationships. Alternative positions within the Neovenatoridae, Allosauroidea, and Tyrannosauroidea have also been proposed.

Sigilmassasaurus ( ; "Sijilmassa lizard") is a controversial genus of spinosaurid dinosaur that lived approximately 100 to 94 million years ago during the Late Cretaceous Period in what is now northern Africa. Named in 1996 by Canadian paleontologist Dale Russell, it contains a single species, Sigilmassasaurus brevicollis. The identity of the genus has been debated by scientists, with some considering its fossils to represent material from the closely related species Spinosaurus aegyptiacus, while others have classified it as a separate taxon, forming the clade Spinosaurini with Spinosaurus as

Amtosaurus () is a genus of ornithischian dinosaur based on a fragmentary skull collected from the Late Cretaceous (Cenomanian to Turonian) Bayanshiree Formation of Mongolia and originally believed to represent an ankylosaurid. Hadrosaurid affinities have also been suggested. However, according to Parish and Barrett, this specimen is too fragmentary to be reliably classified beyond an indeterminate ornithischian. A second species assigned to the genus, A. archibaldi, has become the basis of a valid ankylosaurid taxon, Bissektipelta.

Urbacodon (meaning "URBAC tooth") is a genus of troodontid theropod dinosaur. Two species have been described, both of which are known from a partial dentary: U. itemirensis from the Dzharakuduk Formation (Cenomanian) of Uzbekistan and U. norelli from the Iren Dabasu Formation of China. Possible remains are also known from the Bissekty Formation (Turonian) of Uzbekistan.
