A team from the University of Kansas said the microscopic structures are nothing more than tiny gaps in the rock that are packed with lifeless minerals.
Instead of primeval oxygen-producing cyanobacteria, they were found to be bits of the iron mineral hematite.
The scientists who reexamined the rock known as the Apex Chert, have published a study in the journal Nature Geoscience.
