More than 4,300 dinosaur footprints have been discovered in Zhangjiakou, North China's Hebei province, the most found in one spot in the country,
在中国北部的河北省张家口市，人们发现了超过4300个恐龙脚印，这是全国在同一地点发现的恐龙脚印最多的一次，
according to the Department of Natural Resources of Hebei, which recently disclosed related survey results.
相关调查结果由河北省自然资源厅于近日对外公布。
From the footprints, scientists can determine how dinosaurs walked, calculate their length, weight and size, and even estimate their walking speed.
通过这些脚印，科学家可以确定恐龙是如何行走的，计算它们的长度、重量和大小，甚至估计它们的行走速度。
"This rock layer was formed between the Jurassic Period and the Cretaceous Period.
“这一岩层形成于侏罗纪和白垩纪之间。
At that time, the huge layer bestrewed with footprints was preserved.
就是在那个时候，这一巨大的足迹面留存了下来。
Such a huge layer must be the largest currently known in China."
像这么巨大的足迹面，一定是目前中国已知的最大的。”
The site in Zhangjiakou has surpassed the record set at a site in Sichuan province that has over 900 dinosaur footprints.
张家口的这处遗址，已超过此前位于四川省的一处拥有900多个恐龙脚印的遗址的记录。
The site has been covered up for protection after experts carried out three-dimensional imaging and cast molds of the footprints, according to Hebei's natural resources department.
据河北省自然资源部门表示，专家们已对这些脚印进行了三维成像并铸模，之后该遗址被掩盖起来进行保护。
"The process of preserving the footprints is very demanding.
“保护这些足迹的过程，要求非常苛刻。
These exquisite dinosaur footprints that we have discovered have gone through many difficulties and are therefore very rare and precious."
这些精美的恐龙脚印，是我们历经千辛万苦才发现的，因此非常罕见和珍贵。”
