Scientists found that the spread of dinosaurs around the world originated from South America
According to the report, the professionals consider them to be dinosaurs.
The opening was based on the reconstruction of skeletons found in 2009-2010 during excavations in the State of Rio Grande do Sul in southern Brazil.
"The remains of this quality are extremely rare to be found anywhere in the world. These are the best remaining samples. They provide us with vital information on the origin and evolution of dinosaurs, noted by the professor of the University of Lutheran of Brazil.
At the same time, Max Cardoso Langere of the University of São Paulo believes that the facts revealed suggest that South America was the homeland of the dinosaurs.
South America and Africa were the only continent, and according to the data available to date, the dinosaurs spread from South America, according to the scientist.
The names of Buriolestes schultzi and Ixalerpeton polesinensis were assigned to new species. According to scientists, they lived 320 million years ago. The length of Buriolestes schultzi was 1, 4-1, 5 meters, 50 centimetres, weighing 7 kg. Through the reconstruction of this animal skeleton, researchers concluded that the oldest dinosaurs were predators of small sizes and moved on two laps.
With regard to Ixalerpeton polesinensis, it is a 40 cm long, 15 cm high, which weighed about 150 grams. According to scientists, it was compared to medium birds.
