文摘
- •
New sub-micrometre analyses of the famous Apex chert ‘microfossils’ are presented.
- •
Candidate filamentous ‘microfossils’ comprise stacks of phyllosilicate grains.
- •
The distribution of carbon is inconsistent with fossilised prokaryote cells.
- •
Carbon also occurs throughout the quartz matrix and in late stage fractures.
- •
‘Microfossils’ are thus reinterpreted as hydrothermally mediated mineral artefacts.
