Pelagornis

Pelagornis is an extinct genus of giant marine birds characterized by tooth-like bony projections along the beak. Its fossils date from the Paleogene to the Pliocene.

Pelagornithidae: Pelagornithidae is an extinct family of seabirds with tooth-like bony projections on their beaks. Pelagornis belongs to this family of large, long-winged marine birds.
Pelagornis sandersi: Pelagornis sandersi is a species known from a fossil discovered in South Carolina and described in 2014. Its exceptionally large wingspan makes it the best-known example of the genus's giant size.
Dynamic soaring: Dynamic soaring is a flight technique that extracts energy from differences in wind speed or direction across air layers. It is a proposed way Pelagornis could travel long distances over the ocean.
Odontopterygiformes: Odontopterygiformes is an extinct order commonly used for pelagornithid birds with pseudoteeth. This higher-level grouping places Pelagornis among other toothed-beaked seabirds.
Pseudoteeth: Pseudoteeth are pointed bony projections along the beaks of pelagornithid birds. These projections gave Pelagornis its distinctive toothlike beak.
Pelagornis chilensis: Pelagornis chilensis is a species described from Miocene fossils found in Chile. Its well-preserved remains provide evidence about the genus's South American history.
Albatross: Albatrosses are living seabirds known for long-distance flight using extended glides over the ocean. Their soaring offers a living comparison for hypotheses about Pelagornis's flight.
Argentavis: Argentavis is an extinct South American bird often considered one of the largest flying birds known. It provides a terrestrial-associated giant-bird comparison to Pelagornis's marine specialization.
Neornithes: Neornithes is the crown group containing all living birds and their most recent common ancestor. Pelagornis was a member of the broader group that includes every living bird.
Pelagornis mauretanicus: Pelagornis mauretanicus is a species known from Pliocene fossils found in Morocco. It documents the genus's presence in the North Atlantic region late in its history.
