MESOZOIC ERA

This article appears in Volume V18, Page 188 of the Encyclopedia Britannica.

Encyclopedia Britannica - Main :: MEC-MIC
MESOZOIC ERA , in geology, the name given to the period of time between the Palaeozoic and Cainozoic eras; it is synonymous with the older and less satisfactory
term
  " Secondary " as applied to the major divisions of
geological
  time and with the " Flozgebirge " of the Wernerian school. This era is sub-divided into a lower, Triassic, a middle, Jurassic, and an upper, Cretaceous period or epoch. The duration of the Mesozoic era was not more than one fourth of that of the Palaeozoic era, measured by the thickness of strata formed during these periods. It was an era marked by peaceful conditions in the earth's crust and by a general freedom from volcanic activity. The sediments as a whole are characterized by the prevalence of limestones as compared with those of the preceding era; they are seldom much altered or disturbed except in the younger
mountain
  regions. Mammals, represented by small marsupials, and primitive forms of birds and bony fishes make their first
appearance
  in rocks of Mesozoic age. Saurian
reptiles
  played an extremely prominent
part
 ; ammonites and belemnites lived in extraordinary variety in the seas along with the echinoids and pelecypods, which had to a
great
  extent supplanted the crinoids and brachiopods of the preceding periods. The first clear indications of monocotyledonous and dicotyledonous angiosperms made their
appearance
 , while Cycads and Conifers constituted the bulk of the land
flora
 .
