Abstract
Arising from: J. V. Bailey, S. B. Joye, K. M. Kalanetra, B. E. Flood & F. A. Corsetti Nature 445, 198–201 (2007)10.1038/nature05457; Bailey et al. reply
Bailey et al.1 propose that the Ediacaran microfossils Megasphaera and Parapandorina, previously interpreted as animal resting eggs and blastula embryos2, represent _Thiomargarita_-like sulphide-oxidizing bacteria, claiming that this interpretation better explains their abundance and taphonomy. Here we highlight important observations that significantly weaken the authors' conclusions.
