Excessive fossils unearthed in Argentina’s southern Patagonia region provide ancient evidence that some dinosaurs thrived in complex and well-organized herds, and that adults cared for the young and shared common ground.
Scientists said on Thursday that the fossils contained more than 100 dinosaur eggs and 80 teens and adults eating jurasic time plants. Musawrus Patagonikus20 Including amazingly complete skeletons.
The researchers said that the animals had suffered mass deaths, perhaps due to drought, and that their bodies had been buried in wind-blown dust.
Archaeologist Diego Paul, who co-authored the magazine’s research, said: Scientific reports.
He grew up to 20 feet (6 m) tall and weighed about 1.5 tons. He had two pedals as an adult but four times as many newborns. Musawrus lived at the beginning of the Jurassic period, the second of three dynasties. It was a relatively large beast – much larger than the carnivorous dinosaurs of its time. The dinosaurs later became real giants.
“The site is the same,” Paul said. “It protects the dinosaur’s nest, including the weak and tiny dinosaur skeletons, as well as the eggs in the embryo.
At the time of the slaughter, the animals were found to be fragmented and eggs were hatched in one area, and the bones of youngsters were piled up nearby. The eggs are laid in layers in layers. Adults were found alone or in pairs. The so-called “age gap” shows a complex social structure, the researchers said, including adults who eat and care for young people. The researchers assessed the suspicion that members of the herd had returned to the same place on several occasions to create breeding colonies.
“Young people stay with adults until they reach adulthood. According to Vincent Fernandez, a fossil researcher and researcher at the London Museum of Natural History, there is no evidence to support that hypothesis. Herd behavior can protect young and vulnerable individuals from predators.
“It’s a strategy for the survival of a species,” says Fernandez. The earliest evidence of the behavior of dinosaurs was 150 million years ago. The cottage is located on the dry shores of the lake, which show ferns and conifers in hot but seasonal climates. The eggs are about the size of a chicken, and the skeleton fits into the palm of a man’s hand. The adults are as heavy as hippos.
High-resolution X-ray computed tomography has confirmed that the embryos in the eggs are musculoskeletal. Musausus was a type of dinosaur called the Sapodomor, which represents the first great success story among plant dinosaurs. The Saropodomorphs were the forerunners of the evolution of the Saropoods, known for their long necks, tails, and four-legged legs. The largest terrestrial animals in the history of the earth were the successors of the Saropodomorphs, for example, later known as the Argentinian Defendant of Patagonia, probably 118 feet (36 m) tall and over 70 tons.
