List of sauropod species

Last updated

Sauropoda is a clade of dinosaurs that consists of roughly 300 species of large, long-necked herbivores and includes the largest terrestrial animals ever to exist. The first sauropod species were named in 1842 by Richard Owen, though at the time, he regarded them as unusual crocodilians. Sauropoda was named in 1878 by Othniel Marsh. [1]

Contents

Scope

For historical value, this list includes every sauropod species that has been formally named, regardless of whether the species is currently considered to be valid. Invalid species (i.e., species that are regarded as dubious or as a junior synonym of another species) are given a darker gray background.

Mussaurus

Phylogenetic relationships of near-sauropod sauropodomorphs according to McPhee and Choiniere 2018, [2] with Sauropoda sensu lato highlighted in pink and Sauropoda sensu stricto highlighted in red to show the difference between the two definitions

The precise definition of Sauropoda is disputed. One proposed dividing line is to consider as sauropods all species more closely related to derived sauropods than Melanorosaurus , one of the most sauropod-like taxa historically classified as a "prosauropod". The other is to exclude from Sauropoda any species more distantly related to derived sauropods than Vulcanodon , one of the earliest and most basal taxa historically accepted as a sauropod. This leaves an interval of species more closely related to derived sauropods than Melanorosaurus but not so closely as Vulcanodon that are sauropods under one definition but not the other. Many characteristics of sauropods, such as opisthocoelous cervical vertebrae and columnar limbs, evolved within this transitional region, so that species within it may exhibit a combination of characteristics regarded as sauropod-like or non-sauropod-like.

For the purposes of this list, species whose phylogenetic position may fall within the interval between Melanorosaurus and Vulcanodon, or whose status as a sauropod is otherwise regarded as uncertain, are listed separately from unambiguous sauropods.

The third section of this list covers species that were once classified as sauropods, but have been reidentified as belonging to other groups.

The fourth section of this list covers informally named sauropod species.

Unambiguous sauropods

The following is a list of every species of sauropod that has ever been formally named, regardless of whether it is currently considered valid, dubious, or synonymous with another species. Invalid species are given a darker gray background. It does not contain species that have been recovered as basal to Vulcanodon by phylogenetic analysis, which are covered in a separate list below. The list contains the following information:

Sauropodomorphs of uncertain affinity

This section of the list contains sauropodomorphs that are more closely related to eusauropods than Melanorosaurus but not as closely as Vulcanodon, thus lying between the two proposed boundaries of Sauropoda, as well as sauropodomorphs of unspecified phylogenetic position whose status as sauropods is disputed.

Non-sauropodomorphs misidentified as sauropods

This section of the list covers taxa that were at one point referred to Sauropoda, its historical synonyms Cetiosauria or Opisthocoelia, or referred to a taxon that is now regarded as a sauropod, such as the genus Cetiosaurus. However, it excludes sauropodomorphs that were referred to Sauropoda as a result of debate over where the boundary between sauropods and non-sauropod sauropodomorphs lie.

Species misidentified as sauropods
Scientific nameTaxonomic statusCurrent classificationNotes
Cetiosaurus brachyurus
Owen, 1842
Nomen dubium [101] Iguanodon One of the four original species of Cetiosaurus . Referred to Iguanodon in 1849 by Melville, [102] a referral that was still upheld as of 2003. [5]
Hypsibema crassicauda
Cope, 1869
Regarded as a sauropod by Baird and Horner in 1979. [103]
Cetiosaurus rigauxi
Sauvage, 1874
Pliosaurus Sauvage initially interpreted this species, based on a single vertebra, as belonging to Cetiosaurus. In 1895, he reinterpreted it as belonging to the marine reptile Pliosaurus. [104]
Apatodon mirus
Marsh, 1877
Listed as a sauropod by Kuhn in 1937
Tichosteus lucasanus
Cope, 1877
Listed as a member of Cetiosauria by Osborn in 1898 [105]
Epanterias amplexus
Cope, 1878
Theropoda Regarded as a sauropod by Cope; still listed as a sauropod by Romer in 1956.
Brachyrophus altarkansanus
Cope, 1878
Ornithopoda Listed as a sauropod by Kuhn in 1937
Symphyrophus musculosus
Cope, 1878
Subjective junior synonym of Camptosaurus dispar Ornithopoda Listed as a member of Cetiosauria by Osborn in 1898. [105] Has been synonymized with Camptosaurus dispar , but may be a chimera that includes crocodylian material. [106]
Morosaurus marchei
Sauvage, 1898
Nomen dubium Theropoda A tooth formerly referred to this taxon, MG 8779, does come from a sauropod
Succinodon putzeri
Huene, 1941
Teredinidae Described by Huene as the jaw of a sauropod, but later discovered to be the borings of shipworms.
Hypsibema missouriensis
(Gilmore & Stewart, 1945)
Valid Ornithopoda Originally described as a sauropod under the name Neosaurus missouriensis, [107] but the name Neosaurus was preoccupied so it was renamed Parrosaurus missouriensis. Reclassified as a species of Hypsibema in 1979 by Baird and Horner, who regarded the genus as belonging to Sauropoda. [108]
Astrodon pusillus
Lapparent & Zbyszewski, 1957
Nomen dubium Dinosauria Originally described as a species of the sauropod Astrodon . In 1981, Galton reidentified it as belonging to the stegosaurid Dacentrurus . [109] In 2008, Maidment et al. concluded it lacked evidence of stegosaur affinities and should be regarded as an indeterminate dinosaur. [110]

Footnotes

  1. In 2004, Upchurch, Barrett, and Dodson listed Cetiosaurus brevis as a nomen dubium. [4] In 2011, Upchurch, Mannion, and Barrett regarded Cetiosaurus brevis and Pelorosaurus conybeari to be objective synonyms and, based on both the caudal vertebrae associated with the name C. brevis and humerus associated with P. conybeari, regarded the taxon, which they called Pelorosaurus conybeari, to be a valid species. [8]
  2. Some authors have treated Cetiosaurus conybeari Melville, 1849 and Pelorosaurus conybeari Mantell, 1850 as distinct taxa, with the former being based on a series of four caudal vertebrae and the latter on a humerus. [11] [12] [13] Others have regarded Pelorosaurus conybeari as simply Cetiosaurus conybeari assigned to a new genus. [14] [10] [8] Among those who treated P. conybeari as having been named by Mantell and based on a humerus, Blows regarded P. conybeari as a nomen vanum [15] and Upchurch et al. treated it as a valid taxon. [4]
  3. According to Naish and Martill, "sauropod experts seem in universal agreement that ʻC. gigasʼ is a camarasauromorph". [26] Naish and Martill themselves regarded Chondrosteosaurus to be a camarasaurid; [27] in contrast, Upchurch, Mannion, and Barrett regarded the specimen to be a titanosauriform. [8]
  4. Both Marsh and Lydekker named a sauropod genus Titanosaurus in 1877. Because Lydekker's Titanosaurus indicus was published first, Marsh renamed Titanosaurus montanus to Atlantosaurus montanus later that year. [30]
  5. In 2015, Tschopp, Mateus, and Benson argued that D. longus was a nomen dubium. [29] In 2017, Carpenter disputed their claims regarding the status of D. longus [34]
  6. Originally described as Ischyrosaurus , without a species name, by John W. Hulke in 1874. [24] Edward Drinker Cope had already named a genus Ischyrosaurus. In 1888, Lydekker assigned it to Ornithopsis , giving the species name as Ornithopsis manseli, which he credited to an unpublished manuscript by Hulke. [38]
  7. Hatcher incorrectly believed that Haplocanthus had to be changed because it was too similar to Haplacanthus Agassiz, 1845. [42] Nonetheless, the name Haplocanthosaurus became widely used, and in 1991, the ICZN ruled to conserve the name Haplocanthosaurus. [43]
  8. Gigantosaurus had to be renamed because Seeley had already used the name for a different sauropod
  9. In 1988, He et al. regarded it as uncertain whether O. changshouensis belonged to Omeisaurus or Mamenchisaurus. [51] In 1996, Zhang and Chen referred O. changshouensis to Mamenchisaurus in 1996. [52] In 2019, Tan et al. used the name Omeisaurus changshouensis but regarded it as more like Mamenchisaurus than Omeisaurus [53]
  10. Kim formally named a genus Ultrasaurus two years before Jensen did, so Ultrasaurus mcintoshi was renamed Ultrasauros.
  11. The name Protognathus was preoccupied
  12. Issue 10 of volume 30 of the Canadian Journal of Earth Sciences is dated October 1993, but was not actually available until February or March 1994 [56]
  13. Exact date disputed. Article dated July 1, 2005, but copies apparently did not become available until December 18, 2005. [67]
  14. The issue is dated 2009, but the paleontologist Darren Naish reported that it was actually published in 2008. [75]
  15. Originally described as a diplodocid, and recovered as such by Tschopp et al. in 2015 [29] and Tschopp and Mateus in 2017. [77] In contrast, recovered as a dicraeosaurid by Whitlock and Wilson Mantilla in 2020. [39]

<i>Argentinosaurus</i> Late Cretaceous giant sauropod dinosaur genus

Argentinosaurus is a genus of giant sauropod dinosaur that lived during the Late Cretaceous period in what is now Argentina. Although it is only known from fragmentary remains, Argentinosaurus is one of the largest known land animals of all time, perhaps the largest, measuring 30–35 m (98–115 ft) long and weighing 65–80 t. It was a member of Titanosauria, the dominant group of sauropods during the Cretaceous. It is widely regarded by many paleontologists as the biggest dinosaur ever, and perhaps lengthwise the longest animal ever, though both claims have no concrete evidence yet.

<span class="mw-page-title-main">Titanosauria</span> Extinct clade of dinosaurs

Titanosaurs were a diverse group of sauropod dinosaurs, including genera from all seven continents. The titanosaurs were the last surviving group of long-necked sauropods, with taxa still thriving at the time of the extinction event at the end of the Cretaceous. This group includes some of the largest land animals known to have ever existed, such as Patagotitan, estimated at 37 m (121 ft) long with a weight of 69 tonnes, and the comparably-sized Argentinosaurus and Puertasaurus from the same region.

<span class="mw-page-title-main">Nemegtosauridae</span> Extinct family of dinosaurs

Nemegtosauridae is a family of titanosaurian sauropod dinosaurs based on their diplodocid-like skulls. Only three species are known: Nemegtosaurus, Quaesitosaurus and possibly Tapuiasaurus, each from the Cretaceous.

Agustinia is a genus of sauropod dinosaur from the Early Cretaceous of South America. The genus contains a single species, A. ligabuei, known from a single specimen that was recovered from the Lohan Cura Formation of Neuquén Province in Argentina. It lived about 116–108 million years ago, in the Aptian–Albian stages of the Early Cretaceous Period.

<i>Bonitasaura</i> Extinct genus of dinosaurs

Bonitasaura is a genus of titanosaurian dinosaur hailing from uppermost layers of the Late Cretaceous (Santonian) Bajo de la Carpa Formation, Neuquén Group of the eastern Neuquén Basin, located in Río Negro Province, Northwestern Patagonia, Argentina. The remains, consisting of a partial sub-adult skeleton jumbled in a small area of fluvial sandstone, including a lower jaw with teeth, a partial vertebrae series, and limb bones, were described by Sebastian Apesteguía in 2004.

<span class="mw-page-title-main">Macronaria</span> Extinct clade of dinosaurs

Macronaria is a clade of sauropod dinosaurs. Macronarians are named after the large diameter of the nasal opening of their skull, known as the external naris, which exceeded the size of the orbit, the skull opening where the eye is located. Fossil evidence suggests that macronarian dinosaurs lived from the Middle Jurassic (Bathonian) through the Late Cretaceous (Maastrichtian). Macronarians have been found globally, including discoveries in Argentina, the United States, Portugal, China, and Tanzania. Like other sauropods, they are known to have inhabited primarily terrestrial areas, and little evidence exists to suggest that they spent much time in coastal environments. Macronarians are diagnosed through their distinct characters on their skulls, as well as appendicular and vertebral characters. Macronaria is composed of several subclades and families notably including Camarasauridae and Titanosauriformes, among several others. Titanosauriforms are particularly well known for being some of the largest terrestrial animals to ever exist.

<span class="mw-page-title-main">Dicraeosauridae</span> Extinct family of dinosaurs

Dicraeosauridae is a family of diplodocoid sauropods who are the sister group to Diplodocidae. Dicraeosaurids are a part of the Flagellicaudata, along with Diplodocidae. Dicraeosauridae includes genera such as Amargasaurus, Suuwassea, Dicraeosaurus, and Brachytrachelopan. Specimens of this family have been found in North America, Asia, Africa, and South America. In 2023, a dicraeosaurid fossil was discovered in India for the first time. Their temporal range is from the Early or Middle Jurassic to the Early Cretaceous. Few dicraeosaurids survived into the Cretaceous, the youngest of which was Amargasaurus.

<i>Isisaurus</i> Extinct genus of dinosaurs

Isisaurus is a genus of titanosaurian dinosaur from the Late Cretaceous Lameta Formation of India and Pab Formation of Pakistan. The genus contains a single species, Isisaurus colberti.

Gobititan is a genus of herbivorous sauropod dinosaur from the Aptian faunal stage of the Early Cretaceous. The name of this genus is derived from the Gobi Desert region and the Titans of Greek mythology, which is a reference to its large body size. The specific name shenzhouensis, is derived from "Shenzhou", an ancient name for China.

<i>Phuwiangosaurus</i> Extinct genus of dinosaurs

Phuwiangosaurus is a genus of titanosaur dinosaur from the Early Cretaceous (Valanginian-Hauterivian) Sao Khua Formation of Thailand. The type species, P. sirindhornae, was described by Martin, Buffetaut, and Suteethorn in a 1993 press release and was formally named in 1994. The species was named to honor Princess Maha Chakri Sirindhorn of Thailand, who was interested in the geology and palaeontology of Thailand, while the genus was named after the Phu Wiang area, where the fossil was discovered. The precise affinities of Phuwiangosaurus among titanosauriform sauropods are uncertain, though several studies have classified it as a euhelopodid.

<span class="mw-page-title-main">Saltasauridae</span> Extinct family of dinosaurs

Saltasauridae is a family of armored herbivorous sauropods from the Upper Cretaceous. They are known from fossils found in South America, Africa, Asia, North America, and Europe. They are characterized by their vertebrae and feet, which are similar to those of Saltasaurus, the first of the group to be discovered and the source of the name. The last and largest of the group and only one found in North America, Alamosaurus, was thirty-four metres in length and one of the last sauropods to go extinct.

<span class="mw-page-title-main">Camarasauridae</span> Extinct family of dinosaurs

Camarasauridae is a family of sauropod dinosaurs. Among sauropods, camarasaurids are small to medium-sized, with relatively short necks. They are visually identifiable by a short skull with large nares, and broad, spatulate teeth filling a thick jaw. Based on cervical vertebrae and cervical rib biomechanics, camarasaurids most likely moved their necks in a vertical, rather than horizontal, sweeping motion, in contrast to most diplodocids.

<i>Ruyangosaurus</i> Extinct genus of dinosaurs

Ruyangosaurus is a genus of titanosauriform sauropod dinosaur recovered from the Early Cretaceous Haoling Formation of China. The type species is R. giganteus, described in 2009 by Lü Junchang et al.

<i>Xianshanosaurus</i> Extinct genus of dinosaurs

Xianshanosaurus is a genus of sauropod dinosaur from the Early Cretaceous (Aptian-Albian) of the Ruyang Basin in Henan Province, China. Its type and only species is Xianshanosaurus shijiagouensis. It was described in 2009 by a team of paleontologists led by Lü Junchang. Xianshanosaurus may be a titanosaur, and Daxiatitan may be its closest relative, but its evolutionary relationships remain controversial.

<span class="mw-page-title-main">Aeolosaurini</span> Extinct clade of dinosaurs

Aeolosaurini is an extinct clade of titanosaurian dinosaurs known from the Cretaceous period of Argentina and Brazil. Rodrigo M. Santucci and Antonio C. de Arruda-Campos (2011) in their cladistic analysis found Aeolosaurus, Gondwanatitan, Maxakalisaurus, Panamericansaurus and Rinconsaurus to be aeolosaurids.

Triunfosaurus is a genus of somphospondylan sauropod dinosaur from the Early Cretaceous of Brazil. It contains a single species, T. leonardii, described by Carvalho et al. in 2017. As a genus, Triunfosaurus can be distinguished from all other titanosaurs by the unique proportions of its ischium. It was initially described as a basal titanosaur, making it the earliest basal titanosaur known; however, subsequent research questioned the identification of the taxon as a titanosaur, instead reassigning it to the Somphospondyli.

<i>Dzharatitanis</i> Extinct genus of dinosaurs

Dzharatitanis is a genus of sauropod from the Bissekty Formation in Uzbekistan, dating to the Turonian age of the Late Cretaceous. The genus contains a single species, Dzharatitanis kingi, named after geologist Christopher King, who contributed to the Cretaceous geology of Asia. It is currently one of two known sauropods from the Bissekty Formation, alongside an indeterminate titanosaur. In its original publication it was considered to be a member of Rebbachisauridae, but later papers considered it to be a titanosaur.

The sauropod hiatus is a period in the North American fossil record for most of the Late Cretaceous noted for its lack of sauropod remains. It may represent an extinction event, possibly caused by competition with ornithischian herbivores, habitat loss from the expansion of the Western Interior Seaway, or both. Alternatively, it has been argued that the hiatus represents a decrease in inland deposits that would have effectively preserved the animals, creating the illusion of an extinction. The sauropod hiatus ended shortly before the end of the Cretaceous, with the appearance of Alamosaurus, most likely an immigrant from South America, in the southern parts of North America.
