Geologists and geomorphologists describe the Earth’s geologic history through a temporal system known as the geologic time scale (Table 10b-1).On this scale, time is measured using the following four units of time: eons, eras, periods and epochs.All of these temporal subdivisions are established on the occurrence of some important geologic event.

During the Mesozoic era there were a number of lineages of marine reptiles.In comparison with the mammals, many more types of reptiles, having attained an existence on land, returned to the seas.Aquatic adaptation (whether freshwater, estuarine, or marine) is a common phenomenon among reptiles, due to their low metabolic rate, tolerance of anoxia and of low body temperatures, and easy.

Fossils are the remaining evidence of life that flourished millions of years ago. They are generally found in layers of sedimentary rocks originally deposited by the erosive action of water. Using modern technology, scientists have been able to determine the age of rock and mineral deposits as well as that of the formations in which fossils are found.
