List of informally named pterosaurs

Last updated

This list of informally named pterosaurs is a list of pterosaurs that have not been formally published. This can include unavailable names that have not been published under a valid name. The following types of invalid names are present:

Contents

P

Pricesaurus

"Pricesaurus megalodon" ("Llewellyn Ivor Price lizard") is a nomen nudum based on remains currently assigned to Anhanguera . The remains were first brought up in a lecture by Rafael Gioia Martins-Neto in 1986. He notes several distinct features, but further research proved that all noted features are non-diagnostic and the taxon was ruled invalid due to improper naming conventions. [1]

R

Rhamphodactylus

"Rhamphodactylus" is a nickname given to fossils of what is likely a basally-branching pterodactyloid from the Mörnsheim Formation by Oliver Rauhut in 2012. The name references the mosaic of features that seem to recall both Rhamphorhynchoidea and Pterodactyloidea. The preserved skull bones are especially similar to Pterodactylus , the tail is similar to rhamphorhynchoids but also Darwinopterus , the shoulder and arm bones are similar to Rhamphorhynchus , and the metacarpal is almost exactly intermediate the two major clades. While the fossil material has been recognized as likely belonging to a new taxon, a proper description has not been published. [2] Some publications have used the nickname "Rhamphodactylus" in reference to this important fossil, even including it in phylogenetic analyses, which have recovered it as a basal pterodactyloid within Monofenestrata. [3] [4] A similar fossil, also with mosaic "transitional" features is known from the Painten Formation of Germany. [5]

S

Saraikisaurus

"Saraikisaurus" ("Saraiki lizard") is a nomen manuscriptum based on a dentary (MSM-157-16) found in the Late Cretaceous (Maastrichtian)-aged Pab Formation or Vitakri Formation of Pakistan. The name was proposed by Sadiq Malkani in a conference in 2013 [6] and was described in 2015 but the paper was not peer-reviewed. [7] The intended binomial is "S. minnhui" and it was probably a basal pterodactyloid, although Malkani created further classification (Saraikisauridae, Saraikisaurinae) but both the family and subfamily Malkani assigned to it are monotypic, containing only "Saraikisaurus" itself. In 2021, Malkani attempted to formally described this and other taxa in Scientific Research Publishing, a known predatory publisher. [8]

Satsuma-yokuryu

"Satsuma-yokuryu" (薩摩翼竜, "Satsuma (old name of Kagoshima) pterosaur") is a nickname given to fossil of partial limb bone of pterosaur described from Cenomanian Goshoura Group, Shishijima Island, Kagoshima Prefecture in Japan. [9] Nearby site also produced fossils of plesiosaur, "Satsuma-utsunomiya-ryu". [10] This specimen was first discovered by Satoshi Utsunomiya during TV program, he and Yasuhisa Nakajima analyzed material and found to be a part of limb bone. [11] [12] Its wingspan would be around 4 meters (13 ft). [9]

<i>Tupuxuara</i> Genus of azhdarchoid pterosaur from the Early Cretaceous

Tupuxuara is a genus of large, crested, and toothless pterodactyloid pterosaur from the Early Cretaceous period of what is now the Romualdo Formation of the Santana Group, Brazil, about 125 to 112 million years ago. Tupuxuara is a close relative of Thalassodromeus, and both form a group that is either called Thalassodrominae or Thalassodromidae.

Palaeocursornis is a monotypic genus of pterosaurs. The only known species, P. corneti, was described in 1984 based on a single bone interpreted as the distal part of a left femur, found in Early Cretaceous (Berriasian rocks from a mine at Cornet near Oradea in northwestern Romania. It was initially assumed to be a flightless paleognathe bird, possibly a ratite, and later as a more primitive ornithuromorph or non-avialan theropod. However, re-evaluation of the specimen suggested that it was not a femur at all, but the upper arm bone of a pterodactyloid pterosaur similar to Azhdarcho.

Anhanguera is a genus of pterodactyloid pterosaur known from the Early Cretaceous Romualdo Formation of Brazil and the Late Cretaceous Kem Kem Group of Morocco. This pterosaur is closely related to Ornithocheirus, but belongs in the family Anhangueridae. The generic name comes from the Tupi words añanga, meaning "spirit protector of the animals" + wera "bygone".

<i>Arambourgiania</i> Genus of large azhdarchid pterosaur from the Late Cretaceous

Arambourgiania is an extinct genus of azhdarchid pterosaur from the Late Cretaceous period of Jordan, and possibly the United States. Arambourgiania was among the largest members of its family, the Azhdarchidae, and it is also one of the largest flying animals ever known. The incomplete left ulna of the "Sidi Chennane azhdarchid" from Morocco may have also belonged to Arambourgiania.

<span class="mw-page-title-main">Pterodactyloidea</span> Suborder of monofenestratan pterosaurs

Pterodactyloidea is one of the two traditional suborders of pterosaurs, and contains the most derived members of this group of flying reptiles. They appeared during the middle Jurassic Period, and differ from the basal rhamphorhynchoids by their short tails and long wing metacarpals. The most advanced forms also lack teeth, and by the late Cretaceous, all known pterodactyloids were toothless. Many species had well-developed crests on the skull, a form of display taken to extremes in giant-crested forms like Nyctosaurus and Tupandactylus. Pterodactyloids were the last surviving pterosaurs when the order became extinct at the end of the Cretaceous Period, together with the non-avian dinosaurs and most marine reptiles.

Doratorhynchus is a generic replacement name for Pterodactylus validus, in 1875 suggested by Harry Govier Seeley. Today it is considered a nomen vanum.

<i>Altmuehlopterus</i> Genus of pterodactyloid pterosaur from the Late Jurassic

Altmuehlopterus is a genus of pterosaur belonging to the Pterodactyloidea. It lived in the Late Jurassic of what is now Germany. It was formerly known as "Daitingopterus", a nomen nudum, informally coined in 2004.

<span class="mw-page-title-main">Lonchodectidae</span> Family of pteranodontoid pterosaurs

Lonchodectidae or Lonchodraconidae is a group of pterosaurs within the clade Pterodactyloidea. It has variously been considered to be within Ctenochasmatoidea, Azhdarchoidea and Pteranodontoidea. They are notable for their high, conical tooth sockets and raised alveolar margins.

<span class="mw-page-title-main">Ornithocheiroidea</span> Clade of pterodactyloid pterosaurs

Ornithocheiroidea is a group of pterosaurs within the extinct suborder Pterodactyloidea. They were typically large pterosaurs that lived from the Early to Late Cretaceous periods, with fossil remains found all over the world except Antarctica.

<i>Volgadraco</i> Genus of ornithocheiroid pterosaur from the Late Cretaceous

Volgadraco is a genus of pterodactyloid pterosaur from the Upper Cretaceous of European Russia. Volgadraco was originally classified as an azhdarchid. However, recent studies have concluded that it may belong to either the family Nyctosauridae, or the family Pteranodontidae.

<span class="mw-page-title-main">Pteranodontia</span> Clade of pteranodontoid pterosaurs

Pteranodontia is an extinct group of ornithocheiroid pterodactyloid pterosaurs that lived during the Late Cretaceous period of North America and Africa. They were some of the most advanced pterosaurs, and possessed highly specialized cranial crests that may have served as sexual attraction, with males having a much larger crest.

<i>Lonchodraco</i> Genus of lonchodraconid pterosaur from the Cretaceous period

Lonchodraco is a genus of lonchodraconid pterodactyloid pterosaur from the Late Cretaceous of southern England. The genus includes species that were previously assigned to other genera.

<span class="mw-page-title-main">Ornithocheiromorpha</span> Clade of pteranodontoid pterosaurs

Ornithocheiromorpha is a group of pterosaurs within the suborder Pterodactyloidea. Fossil remains of this group date back from the Early to Late Cretaceous periods, around 140 to 92.5 million years ago. Ornithocheiromorphs were discovered worldwide except Antarctica, though most genera were recovered in Europe, Asia and South America. They were the most diverse and successful pterosaurs during the Early Cretaceous, but throughout the Late Cretaceous they were replaced by pteranodontians and azhdarchoids. The Ornithocheiromorpha was defined in 2014 by Andres and colleagues, and they made Ornithocheiromorpha the most inclusive clade containing Ornithocheirus, but not Pteranodon.

<i>Serradraco</i> Genus of pteranodontoid pterosaur from the Early Cretaceous

Serradraco is a genus of Early Cretaceous pterodactyloid pterosaur from the Valanginian aged Tunbridge Wells Sand Formation in England. Named by Rigal et al. in 2018 with the description of a second specimen, it contains a single species, S. sagittirostris, which was formerly considered a species of Lonchodectes, L. sagittirostris. In 2020, Averianov suggested it did not belong in Lonchodectidae.
