nite fauna is famous, and has been studied since the 1800s, Haug, 1889; Uhlig, 1887).
The hemipelagic stratigraphic succession continues with the Scaglia Rossa (Santonian – Maastrichtian),
a powerful unit of well-stratified reddish micritic limestones with Globotruncana (5-25 cm) for
the most part plate-shaped and sometimes chert-containing. The very powerful and complex Mesozoic
succession ends with this basin unit. Paleogene and even Neogene sediments are documented in
marginal areas of the Dolomites system.
In the heart of the Dolomites a very important outcrop of Oligo-Miocene clastic sediments is documented
in the Col Bechei – Croda del Becco/Seekofel/Sas dla Porta crest, in the area of Fanes. These
are absolutely the youngest rocks to be found in the Dolomites. They comprise rounded pebbles of
various nature and size, intermixed with sand and shell remains, algae and shark teeth and are called
Monte Parei Conglomerate. Monte Parei Conglomerate represents coastal sediments deposited at
the base of cliffs or on an articulated and jagged rocky coast dating back to about 25 million years
ago. They are lying uncomformably on Jurassic faulted and folded sediments, therefore documenting
and dating the mesoalpine phase in the Dolomites orogenesis. The Monte Parei conglomerate is
then truncated by a south-vergent overthrust belonging to the neoalpine phase of the orogenesis, being
thus a good constraint to two principal phases of formation of the Southern Alps.
