Abstract

Here we question the conclusions of Rogov et al. (2012), who claim to describe “the oldest evidence of bioturbation on Earth” in the form of meniscate backfi lled burrows and escape traces from late Ediacaran car- bonates of the Siberian Khatyspyt Formation. Because trace fossils can constrain early Metazoan origins, and are used to defi ne the base of the Cambrian Period (Brasier et al., 1994), such a signifi cant claim requires jus- tifi cation by careful interpretation of the material, and critical analysis, both of which appear wanting here. Although we agree that multiple biological and ecological revolutions took place during the late Ediacaran Period, we question whether those events can be tied to these problematic fossils.
