Actually it is not quite a dinosaur, but only dynozavromorf - intermediate between Archosaur and dinosaurs. To date dynozaropodibni animal paleontologists were known only to the territories of Argentina and Brazil, who lived in the late Triassic period of the Mesozoic era. It was thought that the first dynozavromorfy like Laґozuhusy or dinosaurs, such as Hererazavry were small predators horoscope elle that walked on its hind legs. Have happened as they emerged on the territory of South America, and after the extinction of Archosaur spread across the Earth.
In the Triassic period all the continents were joined together in a single nadmateryk - Pang, through horoscope elle which passed some huge faults and mountain ranges. North America and Europe are housed in the northern hemisphere and the south separated by mountain ranges of South America, Africa and India. Southern boundaries of Pangea were merged Antarctica and Australia, which are high mountains in the north and dissociated themselves from Africa and South America. These mountains were a barrier to the spread of different types of contemporary animals and plants. The finds of ancient skeletons Dinosauriformes animals from South America gave reason paleontologists consider the area a center of origin of dinosaurs. However, remained unclear why dinosaurs have arisen there, if between South America and Africa were not barriers, and animals freely spread their vast spaces ... It was suggested that in the middle of the continent there is a huge desert, horoscope elle which also served border.
... In 2007, the international paleontological expedition conducted excavations in southern Tanzania, Africa. Scientists examined sediments of the middle Triassic period, where they found 14 incomplete skeletons Dinosauriformes unknown creatures. The time of residence of the animal on Earth was estimated 243 m milyonolittya from the current day. As it turned out, her age is more ancient horoscope elle by 10-13 million years, rather than the South American Laґozuhusiv (Lagosuchus talanpayenisis Romer, 1972) or Hererazavriv horoscope elle (Herrerasaurus ischigualastensis Reig, 1963); It was only in 2010, after three years of research and preparation of the manuscript, the researchers published in the journal "Nature" (Nature) description oldest Dinosauriformes horoscope elle animals, calling it Asilizavr old (Asilisaurus kongwe horoscope elle Nesbitt, Sidor, Irmis, Angielczyk, Smith et Tsuji, 2010) . The name comes from two languages Swahili and Greek. Asili - Swahili meaning "founder", saurus - Greek means "lizard" and kongwe - from Swahili meaning "ancient." This is the first finding dynozavromorfiv in present-day Africa. horoscope elle
Asilizavr horoscope elle old was fine animal height of 0.5-1 m and a length horoscope elle of 1-3 m, and unlike previously known dynozavromorfiv, moved on four legs. The approximate weight of the animal, depending on the size, was 10-30 kg. He had triangular horoscope elle teeth, and mandibular available rostral outgrowth, which led scientists to omnivorous Asilizavra. Later, horoscope elle this anatomical feature arose independently in two evolutionary branches omnivorous dinosaurs. It is believed that omnivorous in all three cases evolved from predatory horoscope elle ancestors.
The main attention is paid to paleontologists studying ancient Asilizavra relationships. According to the study, this species is the sister group to the family Sylezavryd (Silesauridae Langer et cet., 2010), which combined a primitive Archosaur as signs and symptoms proґresyvnishyh dinosaurs. Sylezavrydy were distributed widely throughout the earth - from Poland to Argentina, they belonged to Dynozavromorfiv. Scientists believe that it is the parent group dynozavromorfy dinosaurs. After the occurrence of the latter, they lived with Sylezavrydamy by the end of the Triassic period when a regular extinction caused by asteroid.
At sites other than bone Asilizavra ancient skeletons were found the remains of various primitive Krokodylomorfiv. Sediments of the two groups horoscope elle of animals in one place and at one time suggests that the ancestors of crocodiles and birds emerged much faster, than it was thought until now.
