1. Foraminiferal faunas from the DSDP originally described as »bathyal« or »abyssal« have to be derived from shallower water deposits (Herb &Scheibnerová, 1977). This contrasts the palaeo-water depths of 3000–4000 m which result from sedimentological and palaeo-geographical investigations.

2. There exists a certain diversity in the sedimentary accumulations in both the lower (Kasserine area) and upper (Bled Zelfane area) sectors of this palaeo-relief.
