Researchers discover new species of dinosaur that flew above the reefs and lagoons around Lebanon 95 million years ago and lived on crustaceans

  • A new kind of flying dinosaur has been identified from fossils found in Lebanon
  • The pterosaur roamed above the shallow waters of the Tethys Seaway
  • There could have been as many different species of pterosaurs as there are birds

Researchers have classified a new kind of flying dinosaur after analyzing fossils collected from a limestone quarry in Lebanon.

The fossils are believed to be more than 95 million years old and come from a pterosaur, the most common form of which is the pterodactyl.

The newly identified pterosaur, called Mimodactylus libanensis, is believed to have inhabited the Tethys Seaway, an enormous and shallow body of water that stood between what would become Europe, North Africa, and southeast Asia. 

Scientists have identified a new species of pterosaur, called Mimodactylus libanensis, which they believe lived of crustaceans in the vast lagoons and reefs around Lebanon some 95 million years ago

They subsisted mostly on crustaceans from the large network of reefs and lagoons in the expansive body of water, and are thought to have traveled as far east as China.

‘The diversity of these ancient animals was much greater than we could ever have guessed at, and is likely orders of magnitude more diverse than we will ever be able to discover from the fossil record,’ University of Alberta paleontologist Michael Caldwell told

The new findings suggest that there could have been as many different species of pterosaur as there are bird species today.

The fossil is the first complete pterosaur from Lebanon, and has revealed new insight into the life of the flying dinosaur, which had wingspans of 30 feet and could weigh as much as 550 pounds.

The pterosaur fossil was originally discovered in Lebanon more than 15 years ago

The fossils were originally discovered more than 15 years ago, but it has taken researchers years to fully analyze them. 

The fossils are currently stored in the Mineralogy Museum at Saint Joseph University in Beirut, and the analysis was done in collaboration with researchers from University of Alberta and the Museu Nacional in Rio de Janeiro, Razil.

The pterosaurs were the first vertebrates known to have developed the capacity for flight.

Pterosaurs have been discovered all over the world, and with a number of unique characteristics.

Researchers say the fossils from Lebanon is the first complete pterosaur sample ever discovered

One set of pterosaur fossils was found in Queensland, Australia with sharp fangs that led researchers to suggest it had acted as an apex predator in the region.

Last year, researchers in Utah found evidence of another new kind of pterosaur in Utah, and in Kansas the remains of a prehistoric shark believed to have been one of the pterosaur’s natural predators was found.

Scientists believe that these ancient sharks would jump out of the water and attack pterosaurs when the airborne dinosaur flew low to the surface of the ocean to hunt for fish.


Neither birds nor bats, pterosaurs were reptiles who ruled the skies in the Jurassic and Cretaceous periods.

Scientists have long debated where pterosaurs fit on the evolutionary tree.

The leading theory today is that pterosaurs, dinosaurs, and crocodiles are closely related and belong to a group known as archosaurs, but this is still unconfirmed.

Pterosaurs evolved into dozens of species. Some were as large as an F-16 fighter jet, and others as small as a sparrow.

They were the first animals after insects to evolve powered flight – not just leaping or gliding, but flapping their wings to generate lift and travel through the air.

Pterosaurs had hollow bones, large brains with well-developed optic lobes, and several crests on their bones to which flight muscles attached.
