Pelagornis was a type of giant fossil bird that lived millions of years ago. These amazing birds are now extinct, meaning they no longer exist. One species, called P. sandersi, was one of the biggest birds ever found!
Imagine a bird with a wingspan (the distance from one wingtip to the other) that was twice as wide as the largest Albatross alive today. That's how big P. sandersi was! Its wings could stretch about 6.4 to 7.4 meters (around 21 to 24 feet) across. The fossil of this huge bird is about 25 million years old.
Pelagornis birds belong to an extinct group called pelagornithids. They were special because they had bony, tooth-like bumps on their beaks. These birds were excellent at gliding, which means they could fly long distances without flapping their wings much. Scientists think they lived a life similar to modern albatrosses, soaring over the ocean to find food. The last of these giant birds died out about three million years ago.

What Was Pelagornis?
Pelagornis was a genus of very large birds that are now extinct. They are often called "pseudotooth birds" because of the unique bony projections on their beaks. These weren't true teeth like those of mammals or reptiles, but they looked like them and helped the birds catch slippery prey.
Giant Wingspan and Size
The most famous thing about Pelagornis is its incredible size. P. sandersi had a wingspan of up to 7.4 meters. This makes it one of the largest flying birds known from fossils. To give you an idea, that's longer than a typical school bus!
Other species of Pelagornis were also very large, though perhaps not quite as huge as P. sandersi. Their massive wings allowed them to glide efficiently over the ocean for long periods.
When Did They Live?
Pelagornis birds lived a long time ago, during a period called the Oligocene and Miocene epochs. The oldest fossils are about 25 million years old. The group continued to exist for many millions of years, but they eventually died out around three million years ago. This means they lived for a very long time on Earth.
Where Did Pelagornis Live?
Fossils of Pelagornis have been found in many different parts of the world. This suggests that these birds were widespread across the globe. Their ability to glide over vast ocean distances likely helped them travel far.
Fossil Discoveries Around the World
Scientists have found Pelagornis fossils in places like North America, South America, Europe, and Africa. Each discovery helps us learn more about these ancient birds. For example, P. miocaenus was found in France, and P. chilensis was found in Chile.
How Did Pelagornis Live?
Scientists believe Pelagornis birds lived a life similar to modern albatrosses. They were likely marine birds, meaning they spent most of their lives over the ocean.
Oceanic Lifestyle
Their large wings and light bones were perfect for soaring over the sea. They probably fed on fish and squid that they caught near the water's surface. The bony "pseudoteeth" on their beaks would have been very useful for gripping their slippery prey.
Gliding Experts
These birds were masters of gliding. They could use ocean winds to stay in the air for a long time without much effort. This allowed them to cover huge distances while searching for food. This efficient way of flying is called dynamic soaring.
Why Did Pelagornis Become Extinct?
Like many other ancient animals, the Pelagornis group eventually died out. The exact reasons for their extinction are not fully known.
Possible Causes of Extinction
It's possible that changes in ocean currents, climate, or the availability of their food sources played a role. Competition with other marine predators might also have contributed to their decline. The last Pelagornis birds disappeared about three million years ago.
