# List of vertebrate fauna of the Maastrichtian stage

This is an incomplete list that briefly describes vertebrates that were extant during the Maastrichtian, a stage of the Late Cretaceous Period which extended from 72.1 to 66 million years before present. This was the last time period in which non-avian dinosaurs, pterosaurs, plesiosaurs, and mosasaurs existed.

Its fossils consist solely of a partial skull. Long, low and horse-like with frontally located peg-like teeth, it is similar enough to the skulls of Diplodocus and its kin to have prompted informed speculation that the missing body was formed like those of diplodocids. It is possible that Nemegtosaurus, also known from only skull material, is a very close relative of Quaesitosaurus, if not indeed a variation of the same animal. | Aeolosaurus Alamosaurus Ampelosaurus Bruhathkayosaurus Huabeisaurus Hypselosaurus Isisaurus Magyarosaurus Nemegtosaurus mongoliensis Opisthocoelicaudia Quaesitosaurus Rapetosaurus Saltasaurus |

| †Saltasaurus †Saltasaurus loricatus | 85-70 Ma | Lecho Formation, Salta Province, Argentina Uruguay | A well-known saltasaurine saltasaurid. Relatively small among typically sized sauropods, though still massive by the standards of modern terrestrial creatures, Saltasaurus is characterized by a diplodocid-like head (with blunt teeth, only in the front of the mouth). It was the first genus of sauropod known to possess armour of bony plates embedded in its skin. The small bony plates (osteoderms) have since been found on other titanosaurs. When the plates of a saltasaur were originally found, independently of skeletal remains, they were assumed to be from an ankylosaur, whose plates they resemble. A crest of scutes has also been discovered running down the back of diplodocid sauropods. | Aeolosaurus Alamosaurus Ampelosaurus Bruhathkayosaurus Huabeisaurus Hypselosaurus Isisaurus Magyarosaurus Nemegtosaurus mongoliensis Opisthocoelicaudia Quaesitosaurus Rapetosaurus Saltasaurus |

Titanosaurus has traditionally been treated as a "wastebin taxon" for poorly preserved sauropod remains that demonstrate a distinctive vertebrae anatomy. The original Titanosaurus remains consist only of limb bones and a few vertebrae that have these characteristics. However, discoveries of more and better-preserved titanosaur species have shown that these once distinctive features are in fact widespread across many genera. Therefore, Titanosaurus itself is considered a nomen dubium by most paleontologists, since the original Titanosaurus specimens cannot be distinguished from those of related genera. | Aeolosaurus Alamosaurus Ampelosaurus Bruhathkayosaurus Huabeisaurus Hypselosaurus Isisaurus Magyarosaurus Nemegtosaurus mongoliensis Opisthocoelicaudia Quaesitosaurus Rapetosaurus Saltasaurus |

| †Vahiny †Vahiny depereti | 70–66 Ma | Maevarano Formation, Mahajanga Province, Madagascar | A rare titanosaur coexisting with the more common Rapetosaurus. It is distinguished from other titanosaurs by characteristics of its braincase, including the basal tubera, basipterygoid processes, parasphenoid, and cranial nerve foramina. Differences in the braincases of Vahiny and Rapetosaurus indicate that they are not closely related to one another. Vahiny is most similar to Jainosaurus, and bears similarities to Muyelensaurus and Pitekunsaurus. | Aeolosaurus Alamosaurus Ampelosaurus Bruhathkayosaurus Huabeisaurus Hypselosaurus Isisaurus Magyarosaurus Nemegtosaurus mongoliensis Opisthocoelicaudia Quaesitosaurus Rapetosaurus Saltasaurus |

| †Arenysuchus †Arenysuchus gascabadiolorum | 67.6–66 Ma | Tremp Formation, province of Huesca, Aragon, Spain | A crocodyloid known a partial skull and four teeth. One feature linking it to early crocodilians is the contact of the frontal bones with the margin of the supratemporal fenestrae, two holes in the top of the skull. The frontal bone is also unusual in that its front end is extremely long. A sharp projection of the frontal divides the nasal bones, making up most of the midline length of the snout. Usually, the nasal bones would occupy the midline and the frontal would be restricted near the eye sockets. Near the frontal, the lacrimal bones are unusually wide in comparison to their length. | Adamantinasuchus Allodaposuchus precedens Armadillosuchus Araripesuchus wegeneri Brachychampsa Baurusuchus salgadoensis Chenanisuchus Itasuchus Mahajangasuchus Mariliasuchus Montealtosuchus Morrinhosuchus Simosuchus Stratiotosuchus Uberabasuchus |

## †Pterosaurs

†Pterosaurs of the Maastrichtian :
| Taxa | Presence | Location | Description | Images |
| †Aerotitan †Aerotitan sudamericanus | 70 Ma, Maastrichtian | Allen Formation, Argentina | Known to be the first unambiguous azhdarchid from South America. The wingspan has been estimated as at least 5 m (16 ft). | Aerotitan Arambourgiania Eurazhdarcho Hatzegopteryx Phosphatodraco Quetzalcoatlus |
| †Alcione †Alcione elainus | 66 Ma | Oulad Abdoun Basin, Khouribga Province, Morocco | A tiny Nyctosaurid from Africa. | Aerotitan Arambourgiania Eurazhdarcho Hatzegopteryx Phosphatodraco Quetzalcoatlus |
| †Arambourgiania †Arambourgiania philadelphiae | 70.6–66 Ma | Zarqa Governorate, Jordan | An azhdarchid known only from fragmentary remains, this pterosaur had a very complicated past. The neck vertebrae that the species is known from was highly elongated, more so then the vertebrae of Quetzalcoatlus; indicating that this creature was indeed quite large. | Aerotitan Arambourgiania Eurazhdarcho Hatzegopteryx Phosphatodraco Quetzalcoatlus |
| †Barbaridactylus †Barbaridactylus grandis | 66 Ma | Oulad Abdoun Basin, Khouribga Province, Morocco | A relatively large animal for a Nyctosaurid native to Africa. | Aerotitan Arambourgiania Eurazhdarcho Hatzegopteryx Phosphatodraco Quetzalcoatlus |
| †Eurazhdarcho †Eurazhdarcho langendorfensis | 69 Ma | Sebes Formation, Alba County, Romania | A medium-sized azhdarchid (having an estimated wingspan of 3 meters) with some distinctive traits, all present in the cervical vertebrae. | Aerotitan Arambourgiania Eurazhdarcho Hatzegopteryx Phosphatodraco Quetzalcoatlus |
| †Hatzegopteryx †Hatzegopteryx thambema | 66 Ma | Densus-Ciula Formation, Hunedoara County, Romania | An azhdarchid known from incomplete remains. The skull fragments, left humerus, and other fossilized remains indicate it was among the largest pterosaurs, very similar (almost identical) to Quetzalcoatlus. The authors estimated the size of Hatzegopteryx by comparing the humerus fragment, 236 mm (9.3 in) long, with that of Quetzalcoatlus, of which one specimen has a 544 mm (1 ft 9.4 in) long humerus. Observing that the Hatzegopteryx fragment presented less than half of the original bone, they established that it could possibly have been "slightly longer" than that of Quetzalcoatlus. They noted that the wing span of the latter had in 1981 been estimated at 11 to 12 meters (36 to 39 ft), while earlier estimates had strongly exceeded this at 15 to 20 meters (49 to 66 ft). From this they concluded that an estimate of a 12 m (39 ft) wingspan for Hatzegopteryx was conservative if its humerus was indeed somewhat longer than that of Quetzalcoatlus. In 2003 they moderated the estimates to a close to 12 m (39 ft) wing span and an over 2.5 meters (8 feet 2 inches) skull length. In 2010 Mark Witton e.a. stated that any appearance that the Hatzegopteryx humerus was bigger than TMM 41450–3 had been caused by a distortion of the bone after deposition and that the species thus likely had no larger wingspan than Quetzalcoatlus, today generally estimated at 10 to 11 meters (33 to 36 ft). | Aerotitan Arambourgiania Eurazhdarcho Hatzegopteryx Phosphatodraco Quetzalcoatlus |
| †Navajodactylus †Navajodactylus boerei | 75.56–74.44 Ma, Campanian to Maastrichtian | Kirtland Formation, New Mexico, USA | A pterosaur of uncertain affinities with an estimated wingspan of 3.5 m (11 ft). Its autapomorphies largely exist in the unique form of the process on the first wing phalanx for the extensor tendon. | Aerotitan Arambourgiania Eurazhdarcho Hatzegopteryx Phosphatodraco Quetzalcoatlus |
| †Phosphatodraco †P. mauritanicus | 66 Ma | Oulad Abdoun Basin, Khouribga Province, Morocco | The first azhdarchid found in North Africa, as well as being unusual among azhdarchids for having elongate vertebrae at the base of the neck (also with neural spines), interpreted as modified dorsal vertebrae; the neck is also one of the most complete known for azhdarchids. The cervical vertebrae are thought to be a series from the fifth (the longest with a length of thirty centimeters) to the ninth. The individual to which the neck belonged would have had a wingspan of about 5 m (16 ft). | Aerotitan Arambourgiania Eurazhdarcho Hatzegopteryx Phosphatodraco Quetzalcoatlus |
| †Quetzalcoatlus †Quetzalcoatlus northropi | 68–66 Ma | Hell Creek Formation, Montana, USA Javelina Formation, Texas, USA | An azhdarchid named after the Mesoamerican Aztec feathered serpent god Quetzalcoatl. Alongside Q. northropi, a second species exists without an official specific name yet, currently called Quetzalcoatlus sp.. One of the largest-known flying animals of all time, it had a stork-like lifestyle. When it was first discovered, scientists estimated that the largest Quetzalcoatlus fossils came from an individual with a wingspan as large as 15.9 m (52 ft), choosing the middle of three extrapolations from the proportions of other pterosaurs that gave an estimate of 11, 15.5 and 21 meters, respectively (36 feet, 50.85 feet, 68.9 feet). In 1981, further study lowered these estimates to 11–12 m (36–39 ft). More recent estimates based on greater knowledge of azhdarchid proportions place its wingspan at 10–11 meters (33–36 ft). It is known to have a scavenging lifestyle similar to a marabou stork, rather than a fishing lifestyle. | Aerotitan Arambourgiania Eurazhdarcho Hatzegopteryx Phosphatodraco Quetzalcoatlus |
| †Simurghia †Simurghia robusta | 66 Ma | Oulad Abdoun Basin, Khouribga Province, Morocco | A Nyctosaurid native to Africa. | Aerotitan Arambourgiania Eurazhdarcho Hatzegopteryx Phosphatodraco Quetzalcoatlus |
| †Tethydraco †Tethydraco regalis | 66 Ma | Oulad Abdoun Basin, Khouribga Province, Morocco | A late surviving Pteranodontid native to Africa. | Aerotitan Arambourgiania Eurazhdarcho Hatzegopteryx Phosphatodraco Quetzalcoatlus |
| *†Pterosauria indet †Pterosauria indet | 70 to 66 Ma | Inter-trappean beds, India | The only late cretaceous Pterosaur native to India. | Aerotitan Arambourgiania Eurazhdarcho Hatzegopteryx Phosphatodraco Quetzalcoatlus |
