End-Pleistocene Palaeolagoons  The palaeolagoons can have few
tens or hundreds of meters, to few kilometer sice. These shallow
elipticall aligned palaeolagoons are found everywhere in Brazil,
as well as in Argentina, Bolivia, USA, South Africa,
Australia... worldwide, and their cosmogenia could be related to
an actual south palaeometeor shower.... an old meteoroid stream
from a defunct prehistoric comet.... and it may still exist in
the form of a meteor shower in the present. Many astronomers
believe that there is long-term fifteen or thirty million year
cycle to impacts as the result of galactic tides affecting
comets in the Oort cloud believed to surround the solar system
like a halo. In 1982, two British astronomers, S. V. M (Victor)
Clube and William Napier, published a book entitled The Cosmic

occasionally divert giant comets (more than 50 kilometers in
diameter) into the inner solar system into short-period orbits.
