Experts believe tracks made by mystery animal are earliest ever uncovered

The parallel tracks were formed in mud up to 551 million years ago in southern China’s Yangtze Gorges.
They potentially date to 10 million years before the Cambrian Explosion, when arthropod and other animal life rapidly flourished, and when creatures with pairs of legs capable of leaving such footprints were thought to have arisen.
Scientists from the Chinese Academy of Sciences’ NanjingInstitute of Geology and Palaeontology, along with colleagues from Virginia Tech in the US, studies the tracks and burrows found within part of the Denying Formation, a fossil-rich area near the Yangtze River.

Yangtze Gorges:

Some of the cities along the Yangtze like Chongqing have houses/dwellings (along the edges of the Yangtze) that are still be inhabited by families who have been there since the 11th Century -- which is nothing compared to the recently discovered footprint obviously!
