IT IS AN AGE OF HOMININS -THE AGE WHICH MARKS THE BEGINNING OF THE OLD STONE AGE OF OUR PREHISTORY.OUR TRIBE /'RACE ' HAD BEGUN IN LATE MIOCENE BUT IT BECAME CLEARLY RECOGNISABLE IN PLIOCENE AND ARDI OR LUCY -COMMON MOTHER OF ALL HUMANS LIVED IN IT
THIS EPOCH WAS MARKED BY GREAT AMERICAN EXCHANGE DUE TO FORMATION OF PANAMA BRIDGE IT IS ALSO KNOWN FOR MAMMOTHS IN NORTHERN AND TERROR BIRDS AND MARSUPIALS IN SOUTHERN HEMISPHERE .IT WAS ALSO AN AGE OF DECIDUOUS FORESTS SAVANNAS AND GRASSLANDS AND CONTINUED DOMINATION OF ANGISPERMS AND MAMMALS

the latest form of primates
childrenof the great apes we all
Cooling and drying trend had caused
extention of the deciduousforests,and
appearanceof deserts,leadingto greater
restrictionof the tropical jungles.
Coniferousforest had extended
in the north up to arcticcircle
but it is the flora and fauna of
the tropicswhich wrote history
for it is in the tropics& subtropics
in jungles woodlands & grasslands
the evolutionwhich proceeded became
the hallmarkof this epoch in particular
