transgression (Late Paleocene) in the Western Aures (Algeria), based on the foraminiferal assemblages of El Kantara section.
For instance, the Thanetian
Age--a 3.2-million-year stretch during the Paleocene Epoch--is marked by just one of many reversals in Earth's magnetic field.
On the basis of the fauna recorded the age of the Patala Formation in this area (according to modern Shallow Benthic Biozones) is SBZ 4-5 and boundary between SB-4 and SB-5 zones (between Thanetian
and Ilerdian) is marked within Patala Formation at a level of 61 meters from its lower contact with Lockhart Limestone.
The oldest occurrence of accepted Florshuetzia pollen is from the late Paleocene Thanetian
(58.7-55.8 Ma) of south central France which was then at the southern border of the Tethys (Fig.
They prograde toward the northeast and lie at the bottom of two channels, which cut into the underlying Thanetian
In the Gafsa area, the Thanetian
phosphate beds are characteristically exposed on the flanks of elongated dome-like anticlinal structures.
A new late Ypresian species of Asterigerina and the first records of Ornatorotalia and Granorotalia from the Thanetian
and upper Ypresian of Turkey.
On the basis of recorded fauna the age of Lockhart Limestone in this area is Thanetian
Miscillena miscella, Lockhartia conditi, Lockhartia haimei and Ranikothalia sindensis revealed shallow Benthic Foraminiferal Zone SBZ 4 of Thanetian
age for the Lockhart Limestone.
The limestones are fossiliferous and, on the basis of fauna contained in the limestone, a Danian to Thanetian
age has been assigned to the Rakhshani Formation (Raza et al, 2001).
Among these taxa Rotalia trochidiformis appears first in the Late Palaeocene (Thanetian
) SBZ 3 and disappears in the Middle Eocene (late Lutetian) SBZ 16, as documented from various Tethyan regions such as Pakistan, India, Qatar and northeast Turkey (Weiss, 1993; Akhtar and Butt, 1999; Inan et al., 2005; Ozgen-Erdem et al., 2005; Mathur et al., 2009; Afzal et al., 2010).
