Pelagornis

A long time ago, giant birds lived by the sea.

These birds had very wide wings. One kind had the widest wings of any bird ever found.

Their beaks were special. They had bumps that looked like teeth. These bumps helped the birds grab slippery food.

Some of these birds lived 25 million years ago. Back then, the world was warmer. The place where we found one fossil was an ocean.

Workers found a bone while building an airport. It was in a place called South Carolina.

These big birds are now gone. They were truly amazing creatures of the sea.

Pelagornis was a group of giant seabirds that lived long ago.

They are known as pseudotooth birds. This name describes their unique beaks. Their beaks had bony bumps that looked like teeth. These were called pseudoteeth. These bumps helped the birds grab slippery prey.

One species, Pelagornis sandersi, was truly massive. It had the widest wingspan of any bird ever found. Its wings reached about 6 meters across.

That is twice as wide as a wandering albatross. A wandering albatross is the largest bird living today.

We know about these birds from fossils. A worker named James Malcom found a bone at an airport. He was building a new terminal in South Carolina. This fossil belonged to P. sandersi. That bird lived 25 million years ago. Back then, the world was much warmer. The area where the bone was found was once an ocean.

These giant birds are now extinct, but their fossils tell a big story.

Pelagornis was a group of prehistoric seabirds that lived a very long time ago.

These birds are known as pseudotooth birds. This name describes a very special feature on their beaks. Instead of having real teeth in sockets, they had bony bumps. These bony extensions are called pseudoteeth. These bumps helped the birds grip slippery prey in the ocean.

They were likely very good at soaring over the waves.

These birds had a very interesting way of working. Their pseudoteeth were not like the teeth in your mouth. They did not have enamel. They also did not grow in sockets. Most importantly, the birds did not lose and replace them throughout their lives. Between every two large pseudoteeth, there was often a single smaller one. This helped them catch food more easily. They also had very large salt glands inside their eye sockets. These glands helped them live in the salty ocean water.

Scientists have spent many years studying these fossils. The first species described was Pelagornis miocaenus. It was found in sediments in Armagnac, France. Scientists once thought it lived in the Middle Miocene time period. Later, they realized it was from the Early Miocene. A single bone from this bird was almost as big as a human arm. Another species, Pelagornis mauretanicus, was named much later in 2008. Its remains were found in Morocco.

One species was much larger than all the others. It is called Pelagornis sandersi.

This bird lived about 25 million years ago during the Oligocene. A worker named James Malcom found its fossil in 1983. He was building a new terminal at the Charleston International Airport in South Carolina. The fossil sat in storage for a long time. Then, a scientist named Dan Ksepka found it again in 2010. He identified it as a new species in 2014. The bird is named after Albert Sanders, who led the excavation.

Pelagornis sandersi was truly a giant among birds.

Its wingspan was estimated to be about 6 meters wide. This is the largest wingspan of any bird ever discovered. It is twice as wide as a wandering albatross. The albatross is the largest bird living today. This massive bird even took the record from another extinct bird called Argentavis magnificens. It is amazing to think such huge creatures once flew through the sky.

Pelagornis is an extinct genus of prehistoric seabirds known as pseudotooth birds.

These animals were massive flyers that lived from the Oligocene to the Early Pleistocene. They are defined by unique structures on their beaks that resemble teeth. These features allowed them to thrive in marine environments long before humans existed. Understanding Pelagornis helps scientists learn about the history of flight and ocean life. They represent some of the most extreme examples of avian size in Earth's history.

The most famous feature of these birds is the presence of pseudoteeth. These are not true teeth found in sockets like those in mammals. Instead, they are bony, knob-like extensions of the bill's margin.

These structures lacked enamel and were not replaced throughout the bird's life. Between two large pseudoteeth, there was often a single, smaller one. This arrangement helped the birds grip and grasp slippery prey in the ocean. To manage the salt from their diet, they also possessed extremely large salt glands inside their eye sockets.

Scientists categorize Pelagornis within the family Pelagornithidae. While they were once thought to be related to albatrosses in the order Procellariiformes, they are now placed in the order Pelecaniformes. Within this order, they are sometimes linked to the suborder Sulae, which includes cormorants and gannets. Other researchers unite them in the suborder Odontopterygia. This classification helps biologists understand how these giant soarers fit into the broader tree of life. Their specialized anatomy suggests they were highly adapted for dynamic soaring over open water.

The history of studying Pelagornis began with the description of Pelagornis miocaenus. This type species was found in Early Miocene sediments in Armagnac, France. The original specimen included a left humerus nearly the size of a human arm. While many species were suspected, Pelagornis mauretanicus was not formally named until 2008. Its remains were discovered in Late Pliocene or Early Pleistocene deposits in Morocco.

These discoveries have slowly mapped out the range and timing of the genus.

One species, Pelagornis sandersi, changed our understanding of avian limits.

This bird lived approximately 25 million years ago during the Oligocene. Its fossil was discovered in 1983 by James Malcom during construction at Charleston International Airport in South Carolina. The specimen was later rediscovered by paleontologist Dan Ksepka in 2010. Ksepka identified it as a new species in 2014. The species is named in honor of Albert Sanders, who led the original excavation. At the time this bird lived, the South Carolina area was covered by ocean.

Pelagornis sandersi was a giant that surpassed all other known flying birds.

Its estimated wingspan reached approximately 6 meters. This is twice the wingspan of the wandering albatross, the largest bird alive today. This discovery allowed Pelagornis sandersi to take the record for the largest wingspan from the extinct Argentavis magnificens. While the skeletal wingspan was roughly 6 meters, the total span including feathers was even larger. Such immense proportions highlight the incredible scale of prehistoric life.

Fossils of the genus have been found across the globe, showing a wide distribution. Specimens have been recovered from the United States in Maryland, Virginia, and North Carolina. Other remains were found in Portugal and Chile, specifically in the Bahía Inglesa Formation. Even fossils from New Zealand and Peru have been linked to these massive birds. This widespread presence suggests that Pelagornis was a successful group of ocean travelers. Their existence connects various prehistoric ecosystems across the ancient oceans.
