First evidence for locomotion in the Ediacara biota from the 565 Ma Mistaken Point Formation, Newfoundland. 2010. A. G. Liu, et al. Geology 38: 123-126.
Abstract: Evidence for locomotion in the Precambrian fossil record is scant. Reliable Ediacaran trace fossils are all younger than 560 Ma, and consist of relatively simple horizontal burrows and trails from shallow-water deposits.
Here we describe an assemblage of macroscopic locomotory traces from deep-water environments at Mistaken Point, southeastern Newfoundland, Canada, dated to ca. 565 Ma.
