New dinosaur tracks discovered at the Chenini site, near Tataouine
(southern Tunisia), are described. Isolated tracks as well as
manus/pes couples of a quadrupedal dinosaur are referred to an
hadrosaurian tracemaker and assigned to cf. Apulosauripus federicianus
(Nicosia et al., 2000b), an ichnospecies originally described in the
Upper Cretaceous carbonate platform deposits of southern Italy. This
discovery thus represents the first report of hadrosaurian tracks in
Africa.
The occurrence of tracks similar to A. federicianus in Tunisia also
represents the first evidence of the presence of comparable ichnofauna
in the Upper Cretaceous of both northern Africa and the carbonate
platforms of the Mediterranean area. Supporting these new data, the
Cenomanian theropod ichnofauna recently described from southern
Tunisia, is here compared with coeval theropod tracks from the
peri-Adriatic carbonate platforms. This comparison documents a number
of shared morphological features, suggesting possible affinities of
the trackmakers and supporting the hypothesis of a subaerial
connection linking the carbonate platforms of the Mediterranean area
to the northern margins of Africa in the mid-Cretaceous.
