Abstract
According
to solar nebula structured ,our planetary system bear from accretion of the dust particles and
planetesimal period, after that
condensation in solar nebula. Thus most of celestial bodies of our
planetary system,like planet,natural satellite,comet, meteorite & asteroids
exhibit the different kind of planetary habitable. Base on energy source as a
sun like star, carbon as a most prominent element of life forms on earth
& percentage of liquid water which consist of celestial bodies. Due to
study of the origin,evolution, distribution & future of life in universe , earth
is the only place know to harbor life. It is depend on minimal condition for
life such as temperature,water,radiation shielding,the stuff of life , sunlight,
oxygen, when planet belongs to G2 type star forming like ours. To revealed evidences
for the planetary habitability & harbor life of planet earth,
paleontological factors are the one of most prominent way . It’s provide a
unique view into the history of life by showing the forms and features of life
in the past & tell us how species
have changed across long periods of the Earth’s history. Though the fossil
record does not include every planet and animal that ever lived, also
compatibility substantial evidence for
the common descent of life via evolution & tend to explain about other
habitable planets(one upon which living beings not unlike terrestrial organisms)
like Gliese 581c & Kepler-452b which consisted in out of our solar system. There
are massive possibility of habitable zone around other stars &
search for extraterrestrial microbial life,such as found from the examination
of the Allan hills 84001 meteorite like
microfossil .Also undeniable fossils (meteorite
type) which carried out from
aranaganwila _sri lanka , exhibited the ample evidences for
extraterrestrial microbial life. Thus
our aims to be explore dominate paleontological factors (Macro fossils/
Pleistocene) in sabaragamu basin sri lanka,which tend to explain comparative
model of Harbor life of planet earth.
