Their fossil remains have been found all over the world in rocks dating between the Early Paleocene and the Pliocene - Pleistocene boundary.
The Odontoanserae is a proposed clade that includes the family Pelagornithidae (pseudo-toothed birds) and the clade Anserimorphae (the order Anseriformes and their stem-relatives). [2] The placement of the pseudo-toothed birds in the evolutionary tree of birds has been problematic, with some supporting the placement of them near the orders ...

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 ...

Mesoplodont whales are 16 species of toothed whale in the genus Mesoplodon, making it the largest genus in the cetacean order. [2] Two species were described as recently as 1991 (pygmy beaked whale) and 2002 (Perrin's beaked whale), and marine biologists predict the discovery of more species in the future. [3]

The first spade-toothed whale bones were found in 1872 on New Zealand’s Pitt Island. Another discovery was made at an offshore island in the 1950s, and the bones of a third were found on Chile ...
