"The Vertebrata of the Cretaceous formations of the West. Marsh, O. C. 1881. Two species of Pteranodon are traditionally recognized as valid: Pteranodon longiceps, the type species, and Pteranodon sternbergi. [12], The wing shape of Pteranodon suggests that it would have flown rather like a modern-day albatross.

Marsh, O. C. 1882. However, the name Sternbergia was preoccupied, and in 1978 Miller re-named the species Pteranodon (Geosternbergia) sternbergi, and named a third subgenus/species combination for P. longiceps, as Pteranodon (Longicepia) longiceps.

Pterosaurs were carnivores, though some may have occasionally ate fruits, Hone said. [12], Scientific interpretations of the crest's function began in 1910, when George Francis Eaton proposed two possibilities: an aerodynamic counterbalance and a muscle attachment point. longiceps. [12] Eaton had suggested that a secondary function of the crest might have been as a counterbalance against the long beak, reducing the need for heavy neck muscles to control the orientation of the head. Because the specimen was millions of years younger than any known Geosternbergia, he assigned it to the new species Geosternbergia maysei. Given the large number of different types of pterosaurs, the physical characteristics of the winged reptiles varied widely depending on the genera. The suggestion that the crest was an air brake, and that the animals would turn their heads to the side in order to slow down, suffers from a similar problem. The smallest pterosaur, called Nemicolopterus crypticus, was discovered in the western part of China's Liaoning Province.

Due to this, and to their gross overall similarity, he suggested that they probably represent chronospecies within a single evolutionary lineage lasting about 4 million years. Schultze, H.-P., L. Hunt, J. Chorn and A. M. Neuner, 1985. [3], While the first Pteranodon wing bones were collected by Marsh and Cope in the early 1870s, the first Pteranodon skull was found on May 2, 1876, along the Smoky Hill River in Wallace County (now Logan County), Kansas, USA, by Samuel Wendell Williston, a fossil collector working for Marsh. Seeley, Harry G. 1871. [12], The sex of the different size classes was determined, not from the skulls, but from the pelvic bones. Kellner followed Miller's opinion that the differences between the Pteranodon species were great enough to place them into different genera.

Pteranodon (/ t ɪ ˈ r æ n ə d ɒ n /; from Greek πτερόν ( pteron, "wing") and ἀνόδων (anodon, "toothless")) is a genus of pterosaur that included some of the largest known flying reptiles, with wingspans over 7 meters (23 feet).They lived during the late Cretaceous geological period of North America in present-day Kansas, Alabama, Nebraska, Wyoming, and South Dakota. Pteranodon was the first pterosaur found outside of Europe. It had a wingspan that ranged from 9 to 20 feet (2.7 to 6 m), according to a 2000 study in Current Research in Earth Sciences, a peer-reviewed bulletin of the Kansas Geological Survey.

"New evidence on the tail of the pterosaur, von Kripp, D. (1943). 1872. More fossil specimens of Pteranodon have been found than any other pterosaur, with about 1,200 specimens known to science, many of them well preserved with nearly complete skulls and articulated skeletons. Marsh recognized that this characteristic warranted a new genus, and he coined the name Pteranodon ("wing without tooth") in 1876. and Schoch (1984) somewhat oddly published another revision that essentially returned to Marsh's original classification scheme, most notably sinking P. longiceps as a synonym of P.

Both size classes lived alongside each other, and while researchers had previously suggested that they represent different species, Christopher Bennett showed that the differences between them are consistent with the concept that they represent females and males, and that Pteranodon species were sexually dimorphic.

Oceans of Kansas – A Natural History of the Western Interior Sea. Nonetheless, Pteranodon is frequently featured in dinosaur media and are strongly associated with dinosaurs by the general public.

Pterosaurs lived among the dinosaurs and became extinct around the same time, but they were not dinosaurs. They subsisted on giant fish that lived in the island's waters. [8], The most distinctive characteristic of Pteranodon is its cranial crest. Species (often dubious ones now known to be based on sexual variation or juvenile characters) have been reclassified a number of times, and several subgenera have in the 1970s been erected by Halsey Wilkinson Miller to hold them in various combinations, further confusing the taxonomy (subgenera include Longicepia, Occidentalia, and Geosternbergia).

Pteranodon, discovered in 1876 by Othniel C. Marsh, was much bigger.

Because the key distinguishing characteristic Marsh noted for Pteranodon was its lack of teeth, any toothless pterosaur jaw fragment, wherever it was found in the world, tended to be attributed to Pteranodon during the late nineteenth and early twentieth centuries. Marilyn Monroe (1926 – 1962) American actress, singer, model

Wellnhofer, P. 1991. A number of additional species of Pteranodon have been named since the 1870s, although most now are considered to be junior synonyms of two or three valid species. However, Miller made several mistakes in his study concerning which specimens Marsh had assigned to which species, and most scientists disregarded his work on the subject in their later research, though Wellnhofer (1978) followed Miller's species list.

Based on these specimens, Cope named two new species, Ornithochirus umbrosus and Ornithochirus harpyia, in an attempt to assign them to the large European genus Ornithocheirus, though he misspelled the name (forgetting the 'e'). Stay up to date on the coronavirus outbreak by signing up to our newsletter today. There are several lines of evidence that support this function of the crests, Hone explained, perhaps most notably that juveniles, which look like miniature versions of adult pterosaurs, don't have crests, suggesting the structures are used for something that is only relevant to adults, such as mating.

NY 10036. Notable authors who have discussed the various aspects of Pteranodon include Bennett, Padian, Unwin, Kellner, and Wellnhofer.

[21], The fact that females appear to have outnumbered males two to one suggests that, as with modern animals with size-related sexual dimorphism, such as sea lions and other pinnipeds, Pteranodon might have been polygynous, with a few males competing for association with groups consisting of large numbers of females. He considered both P. comptus and P. nanus to be specimens of Nyctosaurus, and divided the others into small (P. velox), medium (P. occidentalis), and large species (P. ingens), based primarily on the shape of their upper arm bones.

Marsh reclassified all the previously named North American species from Pterodactylus to Pteranodon. Comments which violate these guidelines may be removed by administrators.

There was some confusion early on as to the size of the Pterodactylus, because some of the specimens turned out to be juveniles rather than adults.

But then things got a complex Given the established status of Pteranodon taxonomy it came as something of surprise when, in 2010, a counterargument to Bennett's interpretation of Pteranodon was published.Another big name in modern pterosaur research, Alexander Kellner, proposed that Bennett's Pteranodon was in fact a 'complex' of at least four species (perhaps five) in three genera …
