Algal origin of sponge sterane biomarkers negates the oldest evidence for animals in the rock record

Ilya Bobrovskiy et al.

Summary: The earliest fossils of animal-like organisms have been pushed back into the latest Ediacaran period, as it was found that the biomarkers 24-isopropylcholestane and 24-n-propylcholestane can be generated from algal C-29 sterol in experiments simulating diagenetic processes. This undermines their status as sponge biomarkers and suggests they may have formed through geological methylation of chlorophyte algae sterols in Neoproterozoic sediments.
