†Acynodon †Acynodon adriaticus †Acynodon iberoccitanus	Early Campanian – Late Maastrichtian 83.5–66 Ma	Italy	Initially placed within Alligatoridae but has since been reclassified as a more basal globidontan, the oldest and most primitive known to date. Recent studies have since resolved Acynodon as a basal eusuchian crocodylomorph, outside of the Crocodylia crown group, and a close relative to Hylaeochampsa.	Allodaposuchus precedens Brachychampsa montana Deinosuchus hatcheri Deinosuchus riograndensis Deinosuchus rugosus Paralligator gradilifrons
†Aigialosuchus †Aigialosuchus villandensis	Early Campanian 83.5–80.5 mya	Kristianstad Basin, Sweden	A member of the extinct family Dyrosauridae, Aigialosaurus was a long- and narrow-snouted crocodylomorph.

The main feature that distinguishes this species from other related crocodylomorphs is the orientation of a groove at the back of the skull called the cranioquadrate passage; unlike the cranioquadrate passages of other crocodylomorphs, which are only visible at the back of the skull, the cranioquadrate passage of this variety is visible when the skull is viewed from the side. The genus includes many species but it may be paraphyletic in regards to its contemporary relative genera Agaresuchus and Lohuecosuchus.

Pteranodon		Kansas, USA, North America	Pteranodon is a genus of pterosaurs which included some of the largest known flying reptiles, with wingspans over 6 metres
Volgadraco		Saratov, Russia	A large pterosaur, either an azhdarchoid, a pteranodontid or a nyctosaurid.

Dinosaurs

During the Campanian age, a radiation among dinosaur species occurred. In North America, for example, the number of known dinosaur genera rises from 4 at the base of the Campanian to 48 in the upper part. This development is sometimes referred to as the "Campanian Explosion". However, it is not yet clear if the event is artificial, i.e. the low number of genera in the lower Campanian can be caused by a lower preservation chance for fossils in deposits of that age. The generally warm climates and large continental area covered in shallow sea during the Campanian probably favoured the dinosaurs. In the following Maastrichtian stage, the number of North American dinosaur genera found is 30% less than in the upper Campanian.

Colepiocephale	Middle Campanian, 80–77.5 mya	Foremost Formation, Alberta	Colepiocephale lambei is a domed pachycephalosaur characterized by the lack of a lateral and posteriosquamosal shelf, a steeply down-turned parietal, and the presence of two incipient nodes tucked under the posterior margin of the parietosquamosal border.	Colepiocephale lambei Goyocephale Hanssuesia sternbergi Homalocephale Prenocephale Sphaerotholus Stegoceras Tylocephale Wannanosaurus yansiensis
Foraminacephale	Late Campanian, 75–73 Mya	Dinosaur Park Formation, Belly River Group, Alberta	Foraminacephale was a small to medium sized pachycephalosaur.
Goyocephale	76 mya	Boro Khovil, Djadochta Formation, Mongolia	Goyocephale is a primitive pachycephalosaurian, and was originally included in the family Homalocephalidae, which united the genus with Homalocephale, which also has a flat skull roof, however, many more recent phylogenetic analyses tend to find Homalocephalidae to be a paraphyletic family, with the genera included simply being consecutive branches sister to Pachycephalosauridae, or as consecutive branches within Pachycephalosauridae. Goyocephale is distinguished from Homalocephale by its overall proportions, the shape of its supratemporal fenestra, and heterodont dentition, although the two share multiple features.
Gravitholus	Late Campanian, 75 mya	Belly River Group, Alberta	There is some debate amongst paleontologists as to whether the animal represents a distinct genus, or if it is synonymous with Stegoceras. Some recent publications indicate it may be a valid genus.
Hanssuesia	Campanian, 77.5–75 mya	Belly River Group, Dinosaur Park Formation and Oldman Formation, Alberta; Judith River Formation, Montana	Distinguished from other pachycephalosaurs by having a depressed parietal region, wide frontoparietal dome, broad nasal characteristics, reduced prefontal lobes, and a reduced parietosquamosal shelf. A possible synonym of Stegoceras.
Homalocephale	Late Cretaceous	Omnogov, Nemegt Formation, Mongolia	Sporting a flat, wedge-shaped skull roof, Homalocephale was different from other pachycephalosaurs.
Ornatotholus	Campanian	Dinosaur Park Formation, Alberta	Likely a synonym of Stegoceras.
Prenocephale	Late Cretaceous	Djadochta Formation, Mongolia	It was similar in many ways to its close relative, Homalocephale but unlike the flattened wedge-shaped skull of later (a possible juvenile trait also potentially seen in early growth stages of Pachycephalosaurus), the head of Prenocephale was rounded and sloping.

Aralosaurus	Upper Santonian-Lower Campanian boundary 85.8 mya	Bostobe Formation, Kazakhstan	A basal lambeosaurine hadrosaur, Aralosaurus was about the size of an elephant. Although very little is known about Aralosaurus (only one near complete skull has been found); it was identified by a beak with nearly 1,000 small teeth in 30 rows. The back of an Aralosaurus skull was wide, a feature suggestive of large jaw muscles used to power its chewing apparatus.

Hadrosaurus	79.5 mya	New Jersey, USA	One of the most basal hadrosaurids and the namesake genus of the family. It was likely bipedal for the purposes of running, but could use its forelegs to support itself while feeding.
Hypacrosaurus	75-67 mya	Alberta, Canada	A derived lambeosaurine, Hypacrosaurus is most easily distinguished from other hollow-crested duckbills by its tall neural spines and the form of its crest. The neural spines, which project from the top of the vertebrae, are 5 to 7 times the height of the body of their respective vertebrae in the back,[4] which would have given it a tall back in profile. The skull's hollow crest is like that of Corythosaurus, but is more pointed along its top, not as tall, wider side to side, and has a small bony point at the rear
Hypsibema		North Carolina and Missouri, USA	A large hadrosauroid known only by a couple of vertebrae.

The upper arm was relatively short.
Pteropelyx	75 mya	Montana, USA	A dubious genus of lambeosaurine hadrosaurs. Historically, several species were assigned to it, all based on extremely fragmentary remains, but there is no evidence to support these assignments.
Rhabdodon	72 mya	France; Spain; Haţeg Island, Romania	It is unclear whether it was an iguanodont or a hypsilophodont, and may be a "missing link" between the two. Current evidence indicates it is an iguanodont similar to Tenontosaurus.
Saurolophus	69.5–68.5 mya	North America, Asia	Saurolophus is known from material including nearly complete skeletons, giving researchers a clear picture of its bony anatomy. S. osborni, the rarer Albertan species, was around 9.8 meters (32 feet) long, with its skull a meter long (3.3 feet). Its weight is estimated at 1.9 tonnes (2.1 tons). S. angustirostris, the Mongolian species, was larger; the type skeleton is roughly 12 meters (39 feet) long, and larger remains are reported.
Sektensaurus	~76–72 mya	Lago Colhué Huapí Formation, Golfo San Jorge Basin, Patagonia, Argentina	A genus of ornithopod dinosaur, possibly an elasmarian. Sektensaurus is the first known non-hadrosauroid ornithopod of central Patagonia.

Theropoda

David J. Varrichio observes that during the late Campanian Alberta and Montana had very similar theropods despite significant differences in the types of herbivorous dinosaur faunas.

†Canadaga			A genus of flightless hesperornithid birds.
†Castignovolucris			An enantiornithe of uncertain affinities. It was estimated to have a wingspan of around 127–185 cm and may have been 75 to 110 cm long when fully grown, making it one of the largest known enantiornitheans to date.
