Age of the Dinosaurs
|We at Geologic Resources
are fascinated by dinosaurs and since they no longer exist, have
collected some pictures of reconstructed dinosaurs. The
period of time (Geologic Time) known as the "Age of the Dinosaurs" was during the
geologic Mesozoic Era which has been dated as from about 65 to 248
million years ago (USGS). Mesozoic time has been divided into three
major periods: the first was named the Triassic Period,
the second the Jurassic Period, and the third the
Cretaceous Period. The Mesozoic Era was brought to a
close by an episode of widespread diastrophism (mountain building
and earth movement) known as the Laramian Revolution.
The close of the Mesozoic Era has been called the "great dying out"
because dinosaurs and many other life forms ceased to exist after
this time (Stovall, et al, 1955).
