First of all, if you have a big test in this, don't you have a textbook or something with this information already in it? Second of all, in the time it took to post this question and wait for an answer you could have easily found this info on the web somewhere else.

Thirdly, it goes like this Cambrian, Ordovician, Silurian, Devonian, Triassic, Jurassic, Cretaceous, then in the cenozoic we have the paleocene, eocene, oligocene, miocene, pliocene, and pleistocene. Please verify this somewhere else on the web as it's been 11 years since I memorized this.

I just want you to know that those periods aren't real. 90% of the Earth doesn't contain most of the periods. And the Grand Canyon the one place on Earth that shows the most of the Geological layers is missing half of them, and the ones it does have, are out of order. (this is from an Evolutionist)
