Pelagornis sandersi comparison with the Andean condor (Vultur gryphus) and the wandering albatross (Diomeda exulans). The sole specimen of P. sandersi has a wingspan estimated between approximately 6.06 and 7.38 m (19.9 and 24.2 ft), [9] giving it the largest wingspan of any flying bird yet discovered, twice that of the wandering albatross, which has the largest wingspan of any extant bird (up ...
Skull of Pelagornis mauretanicus. The biggest of the pseudotooth birds were the largest flying birds known. Almost all [4] of their remains from the Neogene are immense, but in the Paleogene there were a number of pelagornithids that were around the size of a great albatross (genus Diomedea) or even a bit smaller.
Enaliornis was originally named Pelagornis ("sea bird") by Seeley in 1866, but that name was preoccupied by a Miocene bird related to the pelicans. Three species have been described: the small Enaliornis sedgwicki , the medium-sized Enaliornis seeleyi , and the large Enaliornis barretti .
In fact, some studies of skull morphology indicated that the T.merriami were incapable of tearing pieces of flesh off of carcasses in the manner of condors. Alternative viewpoints note that many old world vultures possess large bills, and a longer bill is a common feature among scavenging raptors, as this allows them to probe deeper into large ...
The family Threskiornithidae includes 36 species of large wading birds. The family has been traditionally classified into two subfamilies, the ibises and the spoonbills; however recent genetic studies have cast doubt on this arrangement, and have found the spoonbills to be nested within the Old World ibises, and the New World ibises as an early offshoot.
It is one of the largest flying birds known to have existed, only likely exceeded by measurement of wingspan by Pelagornis sandersi, discovered in 1983. [6] Fossil remains of this species have been dated to Late Miocene, about 6 to 8 million years ago, and one of the few teratorn finds in South America.
Ichthyornis (meaning "fish bird", after its fish-like vertebrae) is an extinct genus of toothy seabird-like ornithuran from the late Cretaceous period of North America.Its fossil remains are known from the chalks of Alberta, Alabama, Kansas (Greenhorn Limestone), New Mexico, Saskatchewan, and Texas, in strata that were laid down in the Western Interior Seaway during the Turonian through ...
