Scientists discovered the dinosaur tomb 220 million years ago. Who buried it?
Scientists believe that the collective death of as many as ten dinosaurs here may be related to the climate and environment at that time. It used to be a water source. Dinosaurs who moved here because of drought thought they could get enough water, but in fact, they didn't, and a large number of dinosaurs still died. In order to explain the accumulation of bones in dinosaur tombs, scientists speculate that there may be a very rare water source, a small lake, where herbivores come in droves to drink. As the lake evaporated and dried up, some weak dinosaurs died around this small lake.
Dinosaurs lived on the earth for 65.438+0.6 billion years, and then died out in an asteroid impact event in 65 million years (not only dinosaurs, but three-quarters of the species on the earth died out at that time). The 220 million-year-old dinosaur tomb discovered by scientists this time was actually discovered in September last year, but the excavation of the whole area was not completed until this year.
Generally speaking, the so-called dinosaur tomb is not surprising. These are just normal "operations" in nature.
