Scientists say that the built mammal built by mammoth-sized mammals that engulfed plants with its horny beak engulfed the European landscape along with the dinosaurs during the Triassic period of 205 to 210 million years.
Scientists have announced a surprising discovery in Poland of fossils of a four-year-old beast called Lysovichi Boyan, which showed that dinosaurs at that time were not the only refugees on Earth.
It also found that a group of reptiles similar to mammals belonging to Livichica, called dicynodonts, had not died out long ago as previously believed.
"We think that this is one of the most unexpected finds of fossils from the European Triassic," says paleontologist Gzegorz Nidzigi from Uppsala University in Sweden.
Lisowicia, the largest known land that is not a dinosaur, lived at that time, was about 4.5 meters high, 2.6 meters high and weighing 9 tons. The only other giants at the time were the early members of the dinosaur group called sauropods who had four legs, long necks and long tails.
"Skulls and jaws of Lisovci were highly specialized: without teeth and mouth was equipped with a horny beak, like in turtles and horned dinosaurs," said Niedzwiedzki, adding that it is unclear if he had bones as some of his relatives did.
The trias was the first opening of the dinosaurs, followed by the Jurassic and Creda periods. The first dinosaurs appeared approximately 230 million years ago. Many of the earliest dinosaurs were modest in size, overshadowed by large terrestrial reptiles, including terrible predators called rausuhans and phytosaurs like crocodiles.
"The late Triassic period was not only the time of dinosaur growth, it was also the time when the last dicynodonts decided to compete with the dinosaurs. Finally, the dinosaurs won this evolutionary game," said palaeontologist Tomasz Suley of the Polish Academy of the Institute of Paleobiology.
Dicynodonts blended with reptilene and mammals. The first ones that appeared millions of years ago before the first mammals evolved into the late triassic, these plant nuances vary in size from small ointments to large browsers. They became the dominant soil herbivores in the middle and late Triass, but until now they were thought to have died out before dinosaurs became dominant land animals.
Scientists have unearthed about 100 bone fragments representing several foxes in the Polish village of Lidovice.
An analysis of the limbs of the creature showed that the bones had a rapid growth rate similar to a mammal or dinosaur.
The research was published in the journal Science.
