Beschreibung:
Planktonic foraminifera first appeared in the
Early Jurassic, approx. 200 million years ago.
They occurred in great abundance in the oceans
only after an important marker Ievel of 130
million years (Early Cretaceous). Since that
time, planktonic foraminifera are the most important
first ranking Stratigraphie markers and
indicators forachanging world's ocean. Knowledge
of the ecological demands of living
planktonic foraminifera help one to understand
their environment in the past because of their
high sensitivity to environmental changes; thus,
they can be used to reconstruct the oceanic paleoclimate
by means of their morphology, faunal
assemblage and chemical composition.
