In the Triassic deposits of Madagascar have found a small fossil reptile. Animal of no more than ten centimeters refers to the group, that led to the giant dinosaurs and pterosaurs. Detailed description of the findings given in the journal Proceedings of the National Academy of Sciences.
Dinosaurs and flying reptiles, the pterosaurs are famous for their huge size. It is therefore surprising that their immediate ancestors were very small. In the Triassic sediments age 237 million years in the South-West of Madagascar found the bones of reptiles, called Kongonaphon kely, or "tiny killer bugs".
Paleontologists from St. Petersburg created the first detailed virtual 3D model of the brain and blood vessels of the head ankylosaur — herbivorous dinosaur, fragments of skull which was found in Uzbekistan. The study is published in the journal Biological Communications.
Ankylosaurs appeared in the middle Jurassic about 160 million years ago and existed until the end of the age of dinosaurs, which ended 66 million years ago. In the course of the study, the authors examined the fragments of fossil skulls of ankylosaur Bissektipelta archibaldi discovered during a series of international expeditions in the late 1990s and early 2000-ies in the area Djarkuduk in the Central Kyzylkum desert in Uzbekistan.
