To confirm that Asia's largest dinosaur fossil was from Gansu, which was very important to Gansu. In China, Sichuan, Xinjiang and Inner Mongolia were known as 'the home of the dinosaurs': now, Gansu was also be added to this rank.

Ancient dinosaurs only grew in beautiful and natural environment, due to climate change, they lost the original environment and finally led to the extinction of dinosaurs and the formation of fossils, which was enough to illustrate that ancient the Haishi Bay was a place that with dense forests, warm climate, rippling blue waves and was suitable dinosaurs and other marine animals.
    The extinction of the dinosaurs was a great loss and there should be a deep thinking. The society was in progress every passing day, science and technology was developing to the trend of high, refined, sharp and new, but our partners have no room for survival.

With regard to this issue, we have held class meeting with a theme of "The Mamenxi dinosaurs that we do not understand”. First of all, we carried out promotion activity among students about our content; we told them our experience in the whole process with a speech and also talked about some of the knowledge of dinosaurs, such as: Mamenxi habits. Although many people often see the stone sculpture there, but they didn’t know the history about it and not to mention that they know the dinosaur’s name. Although it only took a short span of 45 minutes, students have learned a lot of knowledge, a class meeting inadvertently set off a “dinosaur hot”, students who interested in it searched on the internet and exchanged with classmates.

Over-developed industry and the use of fossil fuels contributed to climate warming; excessive deforestation, the decline of "Earth's lungs" function, over-grazing, large areas of land was bare, dust storms swept; over-fishing, and even poaching, species developed from rare to extinctive. The environment was deteriorating and we should wake up and protect our environment for survival. Learning about knowledge about dinosaurs, students had positive response and began to protect and care for the environment. The value of this activity was best expressed.
