World’s earliest known fossil trackways discovered in China

Chinese researchers have discovered the world’s earliest fossilized animal trackways dating back as far as 551 million years in the area of Three Gorges of Yangtze River in central Hubei Province.

The trackways, characterized by two parallel rows of imprints, were found on a dozen fossils, said Chen Zhe, leader of the research program and a member with the Nanjing Institute of Geology and Palaeontology under the Chinese Academy of Sciences.
