A bottomless pit has been discovered in Guizhou, and archaeologists have been digging it for three years. What's in the cave?

As one of the birthplaces of ancient humans, Guizhou has many ancient human fossils and cultural sites. In Guizhou, there are two things that belong to local civilization, one is paper-cutting, which has various forms and unique characteristics; One is delicious food, the main feature of which is sour. Guizhou can be said to be a good place to eat, drink and have fun.

In Guizhou, there is a place called Niupo. In 2008, when an archaeologist conducted a general survey of cultural relics here, he found many holes of different sizes, but it did not attract much attention. It was not until 20 12 that the investigation and exploration of excavated cultural relics began in this place. This excavation doesn't matter, it can't stop at all, and it will take three years to dig!

The most interesting thing about this place is that Niupo site is like a cornucopia. Six different excavations back and forth have unearthed many cultural relics. In the whole process, a * * * unearthed more than 65,438+10,000 stone products, 100 bone wares and some pottery pieces, which can be said to be a bumper harvest, which is of great significance to the history postgraduate entrance examination. In the whole site of civilization, a * * * found seven ash pits, seven tombs, 10 fire sites and two movable walls.

The excavation of the whole Niupo site shows that the whole timeline can be divided into five stages: the first stage is the limestone stone tools made 15000 years ago; The second stage is the fine grinding of stone products before 10200~8700; The third stage is grinding stone tools 8000~5500 years ago; The fourth stage was dominated by stone tools from 5000 to 3000 years ago, but pottery began to appear; The fifth stage is the pottery products in the Spring and Autumn Period and the Warring States Period.

Why is Niupo site like a "bottomless pit", and new discoveries can be made every time it is excavated? The reason lies in the superposition of the bottom layer. With the deepening of excavation, every time it will cause another level of feeling.

The archaeological excavation of Niupo gives us a new understanding of the civilization and connotation of Guizhou, and also shows the important significance and position of Guizhou in the prehistoric civilization of China!
