The Gnathosaurus is a type of ctenochasmatid pterosaur. This dinosaur genus has two species under it, G. subulatus and G. macrurus. The species Gnathosaurus subulatus was discovering in 1833 in the Solnhofen Limestone region of Germany. The remains of the G.macrurus specimen, originally named Pterodactylus macrurus, were captured in the Purbeck Limestone Formation of the United Kingdom.
The meaning of Gnathosaurus translates to 'jawed lizard'. It is said that this species soared above the oceans, feeding on ocean animals. Its fossil remains go back all the way to the Late Jurassic period.
This dinosaur had an extremely wide wingspan of about 5.6 ft (1.7 m)! Juvenile specimens of G. subulatus were identified from the derived bones and skeletons that had previously been identified as those belonging to a separate species, Pterodactylus micronyx. Gnathosaurus subulatus is currently known only from the bones and remains available of the jaw and skulls. Another genus, Aurorazhdarcho, was earlier used as a synonym for the Gnathosaurus genus. However, the adult Aurorazhdarcho micronyx body has a skeleton without a skull. The two cannot be confidently considered to be of the same kind.
The name of this dinosaur species is pronounced 'Naf-oh-sore-us'.
Gnathosaurus dinosaurs are a ctenochasmatid pterosaur type of dinosaur.
The Gnathosaurus species roamed around the Earth during the Tithonian stage of the Late Jurassic period. This species lived 167.7-139.8 million years ago.
The Gnathosaurus became extinct about 139.8 million years ago.
The remains of the two Gnathosaurus species, Gnathosaurus subulatus and Gnathosaurus macrurus were found in different regions. The fossils of the G. subulatus were found in 1833 from the Solnhofen Limestone of Germany. The fossils of G. macrurus were derived from the Purbeck Limestone of the United Kingdom.
It is said that this dinosaur species was an oceanic pterosaur and probably a flying reptile.
Unfortunately, we do not know who the Gnathosaurus, meaning 'jawed lizard', specimens lived with. There is insufficient information on the history of this genus.
We are not aware of the exact lifespan of the Gnathosaurus subulatus.
Sorry, we do not know much information on the reproductive behavior of Gnathosaurus dinosaurs.
The skull of this species was extremely slender and long. The skull was about 11 in (28 cm) long and was adorned with 130 needle-like teeth which were neatly arranged around the side of a slender spoon-shaped tip. It is said that this dinosaur probably led their life similar to modern spoonbills, grabbing food with their jaws.
We've been unable to source an image of Gnathosaurus and have used an image of Plataleorhynchus instead. If you are able to provide us with a royalty-free image of Gnathosaurus, we would be happy to credit you. Please contact us at [email protected].
Unfortunately, there are no records of the total number of bones a Gnathosaurus had.
We do not know how the Gnathosaurus species communicated with each other. It can just be assumed that they might have used vocal and visual displays.
The G. subulatus specimen had an estimated wingspan of about 5.6 ft (1.7 m). Their wingspan was about seven times the wingspan of the Nemicolopterus.
Sorry, we are not aware of this information!
We do not know how much the subspecies of Gnathosaurus dinosaurs weigh.
The female dinosaur of this species was called the Gnathosaura, while the male specimen was called the Gnathosaurus.
Baby dinosaurs, generally, are called hatchlings.
Sorry, we do not have this information. However, it is known that a Gnathosaurus subulatus was a filter feeder. This is quite similar to the Ctenochasma. It is speculated that the teeth formed a 'spoon' structure, which was thought to be the main area to catch prey. This dinosaur would swoop down from the sky, scoop up water in its mouth, and allow it to drain out through the teeth. This would leave behind invertebrates and fish within the mouth, which would be eaten by the G. macrurus and G.subulatus.
Liaodactylus primus from China is one of the earliest pterosaurs to have been discovered which exhibited this filter-feeding technique.
Sorry, there is not much information available on how aggressive the Gnathosaurus was.
Hermann von Meyer was an important name in the dinosaur research field. He proposed a method of classification of all fossil reptiles into different groups based on the usage of limbs or the structure of limbs like toes. Similar to living species such as Protosaurus and Teleosaurus, flying limbs such as Pterodactylus, limbs like heavy mammals such as Iguanodon and Megalosaurus, and limbs used for swimming such as Plesiosaurus and Mosasaurus.
The Solnhofen Plattenkalk, commonly known as Solnhofen Limestone, is a popular geological location that preserves a rare collection of various fossiled organisms. These organisms range from large dinosaurs to soft-bodied organisms like sea jellies. This Jurassic Konservat-Lagerstatte houses fossils of many dinosaur species, including the feathered theropod Archaeopteryx.
The Purbeck Group is also called the Purbeck Limestone Formation, Purbeck Stone, Purbeck Beds, or simply Purbeck Formation. The Purbeck Formation is an Upper Jurassic to Lower Cretaceous lithostratigraphic group located in England. Various insect remains, fossils of dinosaurs, crocodylians, chelonians, and plesiosaurs are found here.
Some dinosaurs to have existed during the Late Jurassic time include the Ceratosaurus, Chaoyangsaurus, Agilisaurus, Barosaurus, Othnielia, and Torvosaurus.
Yes, the Gnathosaurus species did live during the Tithonian stage of the Late Jurassic period.
Parts of the jaws of this dinosaur were first found in 1832. These jaw fragments were derived from the Solnhofen Limestones located in southern Germany. However, these jaw fragments were inaccurately believed to be the jaw piece of a Teleosaurid crocodile by the German paleontologist, Georg zu Munster. He was the one who titled and named the species Crocodilus multidens in 1832.
Following this, another German paleontologist, Hermann von Meyer, classified the same specimen altogether as a new genus and species, Gnathosaurus subulatus. Various scientists such as the German Albert Oppel compared the jaw fragment of various pterosaurs with the G. subulatus jaw fragment. These comparisons concluded that the latter species was more of a ‘flying reptile’, rather than a crocodilian.
In 1951, a better, more complete skull belonging to an adult pterosaur was found and was classified as that of the Gnathosaurus subulatus. Since the G. subulatus is known only through the remains of its jaws and skulls, and the adult Aurorazhdarcho micronyx is known only on the basis of its skeleton which lacks a skull, the two cannot be considered the same. Additionally, in the cladistic analysis carried out to analyze the relationships of both taxa, they were found to be distinct.
Another large specimen, originally called the Pterodactylus macrurus, is known from the United Kingdom’s Purbeck Limestone Formation. Being represented only with neck vertebrae and a partial lower jaw, it is considered to have a much closer connection to the Gnathosaurus, and the binomial name of this species has been changed to G. macrurus.
