Oxygen-related controls on predepositional ichnofacies in turbidites, Guipúzcoan Flysch (Albian-lower Eocene), northern Spain

Sedimentological, geochemical and ichnological analyses of the Albian-Lower Eocene Guipúzcoan Flysch (northern Spain) suggest that dissolved oxygen levels control the size of the preturbidite trace fossils on turbidite bed soles. Low-oxygen-tolerant trace fossils include indistinct, tiny ridges and...
