Based on faunal similarities, the present Pv. eugubina Zone is equivalent to
the same zone recorded from Tunisia (Keller, 1998 b); Egypt (Elnady & Shahin,
2001, Samir 2002 , Luning et al, 1998, Shahin 1992); Spain (Smit 2005); Ain
Settara ,Tunisia (Arenillas et al., 2000); (Li & Keller, 1998 b); (Abramovich and
Keller, 2003); Egypt (Keller, 2002); Eastern Tethys Israel (Keller, 2004), general
(Olsson et al.2000); (Berggren & Norris 1997); (Berggren et al.1995); (Keller
1996); to P1a of (Pardo et al. 1996), (Fig 3. 13-14)
The age estimation of this biozone by Olsson et al., 2000, Li and Keller
1998a, Keller, 2002, 2004, records the earliest Paleocene (Danian), with the
time span of (64.97Ma) to (64.90Ma) estimating absolute ages based on
magnetochron ages. 70Ky ages with 4 Ky/m high rate of deposition in Gali
section. (Figs. 3.12 -14)
Age: Earliest Paleocene (Danian).
