In recent weeks, paleontologists have reported four new species of prehistoric flying reptiles dating back to the mid-Cretaceous, or about million years ago all found in Morocco. These leathery-winged predators, part of an extinct group known as pterosaurs , were excavated from the Kem Kem fossil beds in southeastern Morocco. Three new species of toothed pterosaur, all part of the Ornithocheiridae family, identified from chunks of jaws studded with pointed teeth, were first reported last month in the journal Cretaceous Research.
A fourth pterosaur , Afrotapejara zouhrii , which had no teeth, is the first of its kind found on African soil, identified by part of its skull, according to a University of Portsmouth statement. Researchers hypothesize these soaring hunters had feet-wide wingspans, and snatched fish with their sharp teeth, forming part of an ancient river ecosystem that included crocodiles, turtles and predatory dinosaurs. The fourth species, Afrotapejara zouhrii, would have been similar in size, but toothless with a large crest on the front of its skull.
None of these pterosaurs would have weighed much despite their size. Like modern birds, their bones were thin and hollow, allowing the flying reptiles to reach large sizes without becoming too heavy to take off.

You can find them deep under the ocean, high in the treetops, hidden in swamps, and in fossil records dating back millions of years. They’re reptiles – creatures.

Snakes are elongated, legless, carnivorous reptiles of the suborder Serpentes. Many species of snakes have skulls with several more joints than their lizard ancestors, enabling them to swallow prey much larger than their heads with their highly mobile jaws. To accommodate their narrow bodies, snakes’ paired organs such as kidneys appear one in front of the other instead of side by side, and most have only one functional lung.
Some species retain a pelvic girdle with a pair of vestigial claws on either side of the cloaca. Lizards have evolved elongate bodies without limbs or with greatly reduced limbs about twenty-five times independently via convergent evolution , leading to many lineages of legless lizards.
It might seem puzzling that an economist would study reptiles in the Californian desert – especially their dating rituals. But to Dan Friedman.

Megaevolutionary dynamics and the timing of evolutionary innovation in reptiles
A rare reptile with lineage dating back to the dinosaur age has been found nesting on the New Zealand mainland for the first time in about years. Four leathery white eggs from an indigenous tuatara were found by staff at the Karori Wildlife Sanctuary in the capital Wellington, during routine maintenance work, conservation manager Rouen Epson said. Tuatara, dragon-like reptiles that grow to up to 32ins, are the last descendants of a species that walked the earth with the dinosaurs million years ago, zoologists say.
They have unique characteristics, such as two rows of top teeth closing over one row at the bottom.
The world’s oldest lizard-like reptile, with roots dating back to the Triassic period, has been found breeding again for the first time in years.
A lizard-like creature whose ancestors once roamed the Earth with dinosaurs and today is known to live for longer than years may hold clues to a host of questions about the past and the future. In a study published Aug. It hasn’t changed much in the million to million years since then. Tuatara have been out on their own for a staggering amount of time, with prior estimates ranging from million years, and with no close relatives the position of tuatara on tree of life has long been contentious.
Some argue tuatara are more closely related to birds, crocodiles and turtles, while others say they stem from a common ancestor shared with lizards and snakes. This new research places tuatara firmly in the branch shared with lizards and snakes, but they appear to have split off and been on their own for about million years — a massive length of time considering primates originated about 65 million years ago, and hominids, from which humans descend, originated approximately six million years ago.
One area of particular interest is to understand how tuataras, which can live to be more than years old, achieve such longevity. Examining some of the genes implicated in protecting the body from the ravages of age found that tuatara have more of these genes than any other vertebrate species thus far examined, including humans.
