Pelagornis was a prehistoric bird known for its enormous wingspan, estimated to be over 20 feet, making it one of the largest flying birds ever. It lived in marine environments, soaring over oceans much like modern-day albatrosses. Its beak was lined with tooth-like spikes for catching fish.

The Pelagornis is an extinct genus of seabird known to have existed during the late Paleogene and Miocene epochs. Fossils have been discovered in various locations across the globe, suggesting a widespread distribution. Notable fossil sites include regions in North America, South America, Europe, and Africa. This indicates that Pelagornis species were likely distributed across the Atlantic Ocean and potentially other major oceanic regions.

Pelagornis species were adapted to marine environments, likely inhabiting coastal areas and open oceans. The environmental conditions of these regions during their time would have included a warm climate with abundant marine resources, which facilitated their lifestyle as large, soaring seabirds.

As seabirds, Pelagornis species occupied a niche similar to that of modern albatrosses and petrels. They were likely pelagic, spending much of their life over open water, feeding on fish and squid. Their large wingspans, among the largest of any known bird, suggest they were expert gliders, capable of covering vast distances over the ocean with minimal energy expenditure.
