220 million years ago, the dinosaur tomb was breathtaking! Where is the dinosaur tomb? What is the c

According to AFP, archaeologists in Argentina announced on Wednesday that a 220 million year old 'Dinosaur Cemetery' with about 10 well preserved fossil remains was found in the ischigalasto nature park, 1100 km west of Buenos Aires, Argentina. Are these dinosaur valleys real? How did these dinosaurs die?

The fossils are all scattered in a radius of 1 to 2 meters, and buried in the same soil layer, without sediment. Archaeologists believe that the site is an ancient water source. Because of the drought, a large number of dinosaurs gathered there to find water, but eventually died of thirst.

In fact, as early as last September, archaeologist RicardoMartinez of the University of San Juan discovered the site, but only recently completed the excavation. Martinez said: 'the fossils also include at least seven to eight mammalian ancestors of the size of a bull, two toothed beasts, and a few reptile ancestors of rare crocodiles. '

Archaeologists have taken samples from the fossils for testing. Martinez stressed that these fossils have a history of nearly 220 million years, belonging to the Triassic period, which is not known by human beings, so they are more valuable for research. At present, the world's recognized largest 'Dinosaur Cemetery' is from Lufeng County, Chuxiong, Yunnan Province, China. According to research, there are more than 600 dinosaurs buried here.
