This list of informally named Mesozoic reptiles is a listing of prehistoric reptiles from the Mesozoic era (excluding dinosaurs and pterosaurs) that have never been given formally published scientific names. This list only includes names that were not properly published ("unavailable names") and have not since been published under a valid name. The following types of names are present on this list:

  • Nomen nudum, Latin for "naked name": A name that has appeared in print but has not yet been formally published by the standards of the International Commission on Zoological Nomenclature. Nomina nuda (the plural form) are invalid, and are therefore not italicized as a proper generic name would be.
  • Nomen manuscriptum, Latin for "manuscript name": A name that appears in manuscript but was not formally published. A nomen manuscriptum is equivalent to a nomen nudum for everything except the method of publication, and description.
  • Nomen ex dissertationae, Latin for "dissertation name": A name that appears in a dissertation but was not formally published.
  • Nicknames or descriptive names given to specimens or taxa by researchers or the press.

A

Aust Colossus

The "Aust Colossus" is an informal name given to the giant ichthyosaur specimens (BRSMG Cb3869, BRSMG Cb3870, BRSMG Cb4063 and BRSUG 7007) discovered from the Late Triassic (Rhaetian) Westbury Formation at the Aust Cliff.[1][2] "Aust Colossus" has been tentatively estimated to be even larger than the 25 metres (82 ft) long ichthyosaur Ichthyotitan from the same formation, possibly over 30 metres (98 ft) long, though the authors acknowledge that this is a very speculative estimate.[3]

C

Cystosaurus

"Cystosaurus" is a genus of putative teleosaur from France informally named by Étienne Geoffroy Saint-Hilaire in 1831.[4] Because it was never given formal description, "Cystosaurus" remains a nomen nudum.[5] Cryptodraco was used as an unnecessary replacement name for Cryptosaurus by Richard Lydekker (1889) who believed the name Cryptosaurus was already previously in use for "Cystosaurus".[6]

H

Hadongsuchus

"Hadongsuchus" (crocodile of Hadong County) is an Early Cretaceous (Aptian-Albian) crocodyliform from the Hasandong Formation of South Korea. Known from a 52 mm (2.0 in) long complete skull (KIGAM VP 200401) discovered in 2002, it was informally named as "Hadongsuchus acerdentis" in a 2005 thesis. Certain features of the third premaxillary tooth help distinguish it from other related crocodylomorphs. Like other protosuchians, it is believed to have been a fully terrestrial cursorial animal with a semi-erect posture. Lee (2005) suggested that "Hadongsuchus" and three other crocodyliforms (Shantungosuchus, Sichuanosuchus, and Zosuchus) comprise a new family which represents a sister taxa to the Protosuchidae, with Zosuchus being the closest relative.[7]

Hainosaurus boubker

Hainosaurus "boubker" is an informal species of mosasaur from the Sidi Chennane phosphate quarry in Morocco.[8] The description of H. "boubker" was published by a known predatory journal, Scientific Research Publishing, which places the validity of the publication and this taxon in questionable status.[9][10] Some researchers provisionally considered H. "boubker" as a valid taxon.[11]

I

Induszalim

"Induszalim" is an informal genus of crocodyliform named by M.S. Malkani based on fragmentary remains from the Vitakri Formation of Pakistan. The proposed type species, "Induszalim bala", was named in a 2014 conference abstract, rendering this name a nomen nudum.[12]

K

Khuzdarcroco

"Khuzdarcroco" is an informal genus of purported mesoeucrocodylians proposed by M.S. Malkani in a 2015 conference abstract based on a rib fragment from the Goru Formation of Pakistan. The proposed type species is, "Khuzdarcroco zahri".[13]

M

Monster of Aramberri

Main article: Monster of Aramberri

The "Monster of Aramberri", also known as the "Aramberri pliosaur", is an informal name given to a large pliosaur specimen (UANL-FCT-R2) discovered from the Late Jurassic (Kimmeridgian) La Caja Formation, Mexico.[14] The body length of the "Aramberri pliosaur" is estimated around 10–11 metres (33–36 ft).[15]

N

Narynsuchus

"Narynsuchus" is an extinct genus of goniopholidid. Because it has never been formally described, it is currently considered a nomen nudum. The name was first used in 1990 for fossil material found from a formation called the Balabansai Svita, which forms a lens in site FTA-30 of the Sarykamyshsai 1 locality in the Fergana Valley of Kyrgyzstan.[16] The formation dates back to the Callovian stage of the Middle Jurassic.[17] The known material of the intended type species "Narynsuchus ferganensis" consists of large and characteristically striated teeth as well as a robust left tibia.[18] "Narynsuchus" is thought to have been larger than Sunosuchus, another crocodyliform from Sarykamyshsai 1, due to the greater size of the known elements belonging to the genus.[17] This material was first recognized as belonging to a new crocodyliform in 1989, when it was referred to as an indeterminant species of Peipehsuchus.[18]

P

Platychelone

"Platychelone" is an informal genus of sea turtle from the Maastrichtian type area of Netherlands. Named by Louis Dollo in 1909, the intended type species "Platychelone emarginata" is considered a nomen nudum as the taxon was based on an undescribed, large carapace with no illustrations.[19]

Procoelosaurus

"Procoelosaurus" is an informal genus of purported pterosauromorph from the Late Triassic Cooper Canyon Formation of Texas. Named in a 2002 thesis, the intended type species "Procoelosaurus brevicollis" was classified as an ornithodiran close to pterosaurs based on its hindlimb morphology.[20] Other potential specimens identified as cf. "Procoelosaurus" were noted in a 2008 thesis.[21]

Pteromimus

"Pteromimus" is an informal genus of purported pterosauromorph from the Late Triassic Cooper Canyon Formation of Texas. Named in a 2002 thesis, the intended type species "Pteromimus longicollis" was classified as an ornithodiran close to pterosaurs based on its hindlimb morphology.[20] A cervical vertebra identified as cf. "Pteromimus" was noted in a 2008 thesis.[21]

R

Raptocleidus

"Raptocleidus" is a plesiosaur from the Early Jurassic (Pliensbachian) deposits of Lyme Regis, southern United Kingdom. The genus contained two species, "Raptocleidus blakei" (LEICT G1.2002) and "Raptocleidus bondi" (NHMUK R16330), both of which were informally named in a 2012 thesis. It was likely a small plesiosaur, with an estimated body length of 3 metres (9.8 ft).[22]

Richmond pliosaur

The "Richmond pliosaur", also known as "Penny", is an informal name given to a complete polycotylid specimen (QM F18041) from the Early Cretaceous (Albian) Allaru Formation, Australia.[23][24] Discovered in October 1989, this complete articulated specimen is measured around 5 metres (16 ft) long.[25] Within the family Polycotylidae, it is classified as a member of the clade Occultonectia, which also includes Plesiopleurodon and Sulcusuchus.[26]

S

Satsuma-utsunomiya-ryu

Mandible of "Satsuma-utsunomiya-ryu"

"Satsuma-utsunomiya-ryu" is the nickname given to an elasmosaurid plesiosaur from Kyushu, Japan. It is the oldest known elasmosaurid from East Asia, dating back to approximately 100 million years ago. The known material includes the mandible, hyoid, fragments of the skull, 40 cervical vertebrae, and a limb bone, possibly belonging to a juvenile individual. Features of the tooth surface ornamentation cervical vertebrae, suggest Satsuma-unomiya-ryu may represent a new species. The name references the former province name of the discovery site and the discoverer, Satoshi Utsunomiya.[27][28] In 2021, Ustunomiya and Yasuhisa Nakajima reported the presence of a regurgitated "pellet" around its throat region.[29]

Stereosaurus

"Stereosaurus" is a plesiosaur from the Cambridge Greensand (Cenomanian). The genus contains three species, "Stereosaurus platyomus", "S. cratynotus" and "S. stenomus", all of which were informally coined in 1869 by British paleontologist Harry Seeley, who considered them to be plesiosaurian.[30][31]

Sulaimanisuchus

"Sulaimanisuchus" is an informal genus of purported mesoeucrocodylians from the Cretaceous Vitakri Formation of Pakistan, mentioned by M. Sadiq Malkani in 2010. The proposed holotype is a partial mandibular symphysis. The intended type species is "Sulaimanisuchus kinwai."[32]

T

Tylosaurus borealis

Tylosaurus "borealis" is an informal species of mosasaur, with the known specimen discovered from approximately 55 kilometers (34 mi) northeast of Grande Prairie. It was named in a 2020 thesis by Samuel Garvey who described a partial skull of Tylosaurus catalogued as TMP 2014.011.0001, which makes the specimen the northernmost known occurrence of this genus.[33]

Z

Zahrisaurus

"Zahrisaurus" is an informal genus of purported plesiosaurs from the ?Jurassic Sulaiman Group of Balochistan, described by M. Sadiq Malkani (2019) in Scientific Research Publishing, a known predatory publisher. The proposed holotype is allegedly a portion of the trunk with associated ribs. The intended type species is "Zahrisaurus kilmoolai."[34]
