Abstract
The Hirnantian (latest Ordovician, ~ 444 Ma) glacial advance on the Gondwana shelf succession is documented throughout the Arabian and North African regions with resulting tunnel valleys described for instance in Mauritania (Ghienne et Deynoux 1998) or Libya (Le Heron et al., 2004). Following the work of Abed et al. (1993), Powell et al. (1994) and Turner et al. (2005), field work in Southern Jordan has permitted us to identify nine points with palaeovalley outcrops (fig. 1).
