You guys can see the project, too, if you like. The progect is a website. You have to design a bedroom for a boy who loves the Geologic time scale. Go to www.wix.com/lawnmower1979/earthsciencebedroom to see it. I think thats right, any way...

Precambrian was 4.6 billion to 540 million years ago. Paleozoic was 540 to 245 million years ago. Mesozoic was 245 million to 65.5 million years ago. Cenozoic was 65.5 mya to the present.

I literally just learned this in Earth Science, so trust me.

The Precambrian started about 550-500 million years ago. Up to the Cenozoic era, I think that was the last one before the Triassic era, where dinosaurs first began to appear, I think it was about 150 million years ago.

No no, the Precambrian started 4.6 billion years ago. Then it went into Paleozoic, Mesozoic, and Cenozoic. The Triassic period isn't an era.

Apparently the precambrian era had three eons included, which are Hadean, Archean and Proterozoic. Then Phanerozoic Eon, including the Paleozoic Era and the Cambrian period. The exact time Erath form ed was 4.54 billion years ago. 90 percent of that was the Precambrian Era, up to the Cambrian Period, 530 million years ago, called the 'Cmabrian Explosion'.

Ya know... You're supposed to do science projects yourself. And learn the information that's been given to you so you can do that project. It's like youre asking us to help you cheat on a test...

Asking fanpop to do your homework will never help you learn.

Maybe it will, maybe it won't. Everyone learns in a certain way, as there are many ways tp pick up information and retain it for long periods of time. XD
