Washington: A stout built mammal cousin the size & # 39; elephant that munched on plants filled with cartilage European landscape together dinosaurs Triassiku during the period around 205 million to 210 million years ago, scientists said on Thursday.
Scientists announced the surprising discovered in Poland & # 39; of & # 39 fossils; Beast & # 39; four & # 39; Lisowicia feet called Bojan has shown that dinosaurs behemoths were not the only ones on Earth at that time and the group & # 39; mammal-like reptile that was Lisowicia belongs, called dicynodonts, did not die from the end as previously thought.
"We think it is one of the most unexpected discoveries from the Triassic fossils of Europe", said palaeontologist Grzegorz Niedzwiedzki of & # 39; University & # 39; Uppsala in Sweden.
Lisowicia, the largest animal of not living dinosaur art in his time, was & # 39; about 15 feet (4.5 meters) long, 8.5 feet (2.6 meters) tall and weighed 9 tons. The only other Giants & # 39; at that time were early members of the dinosaur group called sauropods had four & # 39; legs, long necks and long tails.
"The skull Lisowicia and tips were very specialized: toothless mouth and was equipped with & # 39; horny pakkru, such as turtles and lamb dinosaurs"Niedzwiedzki said, adding that it was unclear whether it had tusks and some of her relatives did.
The Triassic was the opening chapter in the age of & # 39; dinosaurs, Followed by Jurassic and Cretaceous periods. First dinosaurs appeared roughly 230 million years ago. Many of the earliest dinosaurs were & # 39; modest size, overshadowed by large reptiles of & # 39; land including fearsome predator called rauisuchians and phytosaurs like crocodile.
"The Triassiku latest period was not only the increasing term & # 39; dinosaurs, Was also the time when the latter decided to compete with deċizjonarji dinosaurs. Finally, dinosaurs won this evolutionary competition ", said Tomasz palaeontologu Sulej of Paleobioloġija Institute of the Polish Academy of Sciences.
Dicynodonts mixed reptilian and mammalian features. First appearing million & # 39; years before the first mammalevolved in the late Triassic, these plant eaters ranged in size from small to large burrowers browsers. They are herbivores become & # 39; the dominant land in the middle and late Triassiku, but & # 39; now thought to have died before dinosaurs became the dominant land animals.
Scientists have unearthed about 100 samples & # 39; bones representing various subjects & # 39; Lisowicia in Polish village & # 39; Lisowice.
foot analysis showed the creature whose bones had rate & # 39; rapid growth similar to a mammal or dinosaur.
The research was published in the journal science.
