In what geologic time period did the Triassic Jurrassic and Cretaceous occur?
That is easy, the first is precambrian time, next you get the paleozoic era, which has Cambrian, ordovician, silurian, denovonian, carbonferious periods, Next you get the mesozoic era which contains the next three, which are triassic, jurrasic, and cretacous periods. Lasty you get the Cenozoic era which contains the last two which are the tertiary, and the quaternary!
