Petrosavra appeared in the triast period and existed for almost 160 million years.
Paleontologists from the University of Southampton found the remains of a new type of pterosaur, a figure not exceeding the house cat. According to scientists, finding proves that there were flying lizards in the Upper Mills era that did not exceed the size of large birds. Researchers report the opening in an article published in Royal Society Open Science.
The pterosaurs are a unit of extinct flying archosars, which appeared in the triast period and existed for almost 160 million years. These animals became the first known vertebrae to develop the ability to travel actively, and they were assisted by light and thin tube bones, as well as by wings of skin warehouses drawn between the side of the body and a long fourth finger on each of the front limbs.
Ocamenalities, including shoulder bones and some spine fragments, found a paleontologist on the island of Hornby, British Columbia, in Canada, in 2009.
A few years later, Canadian Professor Mark Whitton dated them to the upper meal period, the age of the remains could reach 77 million years. Researchers do not rule out that the remains of Hornby are in fact fragments of skeletons of several animals, as they were not connected.
However, the approximate level of their safety, as well as the absence of repetitive parts, suggest that they belonged to the same individual. The new type to which the paleontologists decided not to give a separate name relates to the Azhdarchoide family, which includes some of the largest known pterosaurs, such as ketzalcoatl. However, detected flying lizard Significantly fell within the dimensions: the size of its wings was barely more than one and a half meters, and growth reached only 30 centimetres. The condition of the bones, however, suggests that it was an adult person who attained full development.
