Dinosaur Data
Dinosaurs lived on Earth for millions of years. Scientists study dinosaur bones to find out how they lived and what they looked like.
There were more than 700 different types of dinosaurs! Some dinosaurs ate plants and others ate meat. Some walked on two legs and others walked on four legs. Some could fly and others lived in the sea. They were all different but no one knows what colour or pattern they were.
Dinosaurs disappeared 65 million years ago. What happened? Some scientists think that a large rock fell to Earth. This made the earth much colder and there was no longer any food for the dinosaurs to eat.
The most famous dinosaur is the T-Rex. It was 14 metres long and 5.5 metres high, bigger than a house!

Finding Treasure
Known as one of the most important historical sites along the Yangtze River, the Sanxingdui Ruins keep surprising us.
On March 20, Chinese archaeologists （考古学家） said that they found over 500 artifacts （手工艺品） in six sacrificial pits （祭祀坑） at Sanxingdui, which dates back over 3200 years. They include gold masks, bronzeware （青铜器）, ivory （象牙）, jade （玉器）, and textiles （纺织品）.
Built during the mid and late Shang Dynasty, the site is believed to be the remains （遗址） of the ancient Shu Kingdom. A farmer first found it in 1929. But huge surprises came in 1986. Two sacrificial pits were found by accident when local farmers dug up soil to make bricks （砖块）. They were filled with more than 1000 artifacts, including bronzeware, face masks and “divine trees （神树）” — bronze sculptures （雕塑） of trees.
The newly-found artifacts are similar to those found in 1986. For example, divine trees and bronze masks were found once again. Many of the artifacts had been broken and burned before being buried （掩埋）. This means the pits were probably used for sacrifice according to Lei Yu, a researcher who led the archaeology project.
Other kinds of artifacts were also found. One example is cong （琮）, a jade artifact that was also found at the 5000-year-old Liangzhu Archaeological Ruins in Zhejiang province. This means “the Sanxingdui site had a close connection （联系） with Central China,” said Chen Xiandan, another member of the archaeology project.
