Paleoclimate. In general, the climate of the Cretaceous Period was much warmer than at present, perhaps the warmest on a worldwide basis than at any other time during the Phanerozoic Eon.The climate was also more equable in that the temperature difference between the poles and the Equator was about one-half that of the present. Floral evidence suggests that tropical to subtropical conditions ...Ordovician Period, in geologic time, the second period of the Paleozoic Era.

In its earliest stage of formation, it was uninhabitable as it clumped from a cloud of dust. About 1,000,000,000 years ago, Earth had its first signs of life. Single-celled organisms consumed the sun's energy.The last spiriferid brachiopod (abundant during the Paleozoic Era) went extinct at this time, and in some regions 84 percent of bivalve species went extinct. Although best documented in Europe, biodiversity during this period seems to have decreased around the globe.
