    • Mesozoic In geology, lying, as a part of the geological series so designated, between the Paleozoic and the Tertiary rocks. It is a synonym of Secondary as that term is employed by geologists. The whole series of fossiliferous rocks is divided into Paleozoic, Mesozoic or Secondary, and Cænozoic or Tertiary. The principal subdivisions of the Mesozoic are the Trias or Triassic, the Jura or Jurassic, and the Cretaceous. (See these terms.) The Mesozoic is distinguished for the great development of the Reptilia, and its period has hence been called the “Age of Reptiles.” In the Mesozoic occur the first traces of mammals, of birds, and of fishes with bony skeletons. as well as the first palms and angiosperms.
