The Cretaceous was about 145 million to 66 million years ago. The Cretaceous gets its name from the latin word for chalk, creta, because it includes the layers of this distinctive pure white limestone. It is the last period of the Mesozoic ("middle life") Era.
65 million years ago

In short, no. The Cretaceous period ended 65.5 million years ago, and mammoths first evolved about 5 million years ago.
Velociraptors lived during the Cretacous, 80 million years ago.
probably spinosaurs although not technically dinosaurs the sea living retiles of the late cretacous were truly gigantic
Cockroaches appeared in the early Cretacous period 190-65 million years ago. They were probably the first insects to fly and survived the asteroid impact 65 million years ago probably because they were so widespread.
Tyrannosaurus rex lived between 68 and 65.5 million years ago. That was during the Maastrichtian stage, which was the last stage of the Cretaceous period. The Cretaceous period was the last period of the Mesozoic era.
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!
1) Pangea begun to break apart during this period. 2) Dinosaurs began to evolve during the Triassic Period. 3) The joining and separating of the continents affected which kinds of dinosaurs lived where.
after Jurrasic period it is the Cretaceous period
you are on your period
1st period -Formative Period 2nd period-International Period 3rd period -National Period 4th period -World Music Period
The period after the Devonian Period (416 to 359.2Ma) is the Carboniferous Period (359.2 to 299Ma).
