- •
We examined 3.25 Ga pyritic filamentous objects at the nano-scale.
- •
The filaments contain potential chemical, morphological and textural biosignals.
- •
- •
Isotopic data are consistent with a hydrothermal vent setting for the filaments.
- •
The data are consistent with a biological formation mechanism but not compelling.
