写作资料技巧|Dinosaur Found in China 中国山东发现恐龙化石群

Zhucheng in Shandong province is known locally as dinosaur^{1 恐龙 city and has been the scene of several important finds since the 1960s.}

But researchers from the Chinese Academy of Sciences say a fossil field 化石场 discovered during mining explorations 矿产开采 earlier this year appears to be the largest in the world.

3000 dinosaur bones have been dug up from a single pit 坑 just a few hundred metres long and several thousand others have been unearthed^{2 挖掘 at a number of sites nearby.}

State media say the find includes tyrannosaurus 暴龙 bones as well as what could be the largest duck-billed 鸭嘴恐龙 dinosaur ever excavated^{3 挖掘.}

Most of the fossils dated so far go back to the late Cretaceous period白垩年代, which is around the time when dinosaurs^{4 became extinct 灭绝.}

The scientists say the discovery of so many remains^{5 in a small area could provide clues 线索 as to how they died out.}

Detailed^{6 research on the fossil find is due to be published later next year but further excavations7 will take place in the meantime and the researchers are hoping to find even more dinosaur remains 遗迹.}
