Short summary
In our study we propose new interpretation of commonly found trace fossil of genus Trichichnus which can be regarded as a fossilised bacterial mat system produced by giant sulphur bacteria related to genus Thioploca. We suggest that the bioelectrical processes may occur during some stages of live and/or post-mortem history of Thioploca-housed bacterial consortium. This greatly improves our understaniding of initial colonization of the marine sea floor after improvements of oxygenation.
