Three New Species of Flying Reptiles Discovered – Pterosaurs That Inhabited the Sahara 100 Million Years Ago

A group of flying reptiles that inhabited the Sahara 100 million years in the past has been came upon by way of a University of Portsmouth palaeobiologist and a global workforce of scientists. 

Professor David Martill from Portsmouth and researchers from the United States and Morocco recognized the 3 new species of toothed pterosaurs. The pterosaurs had been section of an historical river ecosystem in Africa that was once complete of lifestyles, together with fish, crocodiles, turtles, and a number of other predatory dinosaurs.

“We are in a golden age for discovering pterodactyls. This year alone we have discovered three new species and we are only into March.” — Professor David Martill, Professor of Palaeobiology

The analysis was once led by way of Megan Jacobs from Baylor University, Texas, who labored along Nizar Ibrahim from the University of Detroit Mercy and Professor Martill from Portsmouth.

The new fossils, printed in the magazine Cretaceous Research, are serving to to discover the very poorly identified evolutionary historical past of Africa all the way through the time of the dinosaurs. The new unearths display that African pterosaurs had been rather very similar to the ones discovered on different continents. 

These flying predators soared above a global ruled by way of predators, together with crocodile-like hunters and carnivorous dinosaurs. Interestingly, herbivores reminiscent of sauropods and ornithischian dinosaurs are uncommon. Many of the predators, together with the toothed pterosaurs, preyed on a superabundance of fish.

Professor Martill,  from the School of the Environment, Geography and Geosciences, mentioned: “We are in a golden age for discovering pterodactyls. This year alone we have discovered three new species and we are only into March.”

The new pterosaurs recognized by way of the researchers from chunks of jaws and enamel, present in the heart Cretaceous Kem Kem beds of Morocco, had wingspans of round 3 to 4 meters. These aerial fishers snatched up their prey whilst on the wing, the use of a murderous having a look set of massive spike-like enamel that shaped a extremely efficient enamel snatch. Large pterosaurs reminiscent of those would were ready to forage over huge distances, very similar to present-day birds reminiscent of condors and albatrosses.

“These new finds provide an important window into the world of African pterosaurs,” mentioned Ibrahim, assistant professor of Biology at Detroit Mercy. “We know so much more about pterosaurs from places like Europe and Asia, so describing new specimens from Africa is always very exciting.”

One of the species, Anhanguera, was once in the past best identified from Brazil. Another, Ornithocheirus, had till now best been present in England and Middle Asia.
