P1 Fossil: Dinosaur

It was found by scientists 500,000 year ago, on and expedition in south America after a earthquake, it was buried through a crack when the ground cracked . They found the entire skeleton in the ruins of many office buildings. After it was over some of the workers went to look for things that weren't damaged. Eventually they got bulldozers to move all the broken pieces of the building and they stumbled across a rib bone and called some scientists to look at the rest.

Precambian Time

The atmosphere was made of CO2 and H2O. The earth was made from molten rock. The oceans were really big because of Pangaea. The moon in the Hadean eon. The earth is 4.6 billion years old. The continents formed in the proterozoic eon. Hadean had marine life, Archaea had plant life, Proterozioc had human life, and phanerozoic had everything that had been created this far.

Phanerozoic Eon

The earth's current atmosphere is an oxidization atmosphere. The Phanerozoic eon is divided into three eras, Paleozoic, Mesozoic and Cenozoic. Paleozoic is the first of these three eras. Invertebrates, marine life, bugs, amphibians, plants, Appalachian Mountains and coal swamps were all made during this era. Next is the Mesozoic. Reptiles, dinosaurs, birds and the Rocky Mountains were all created in this era. Lastly is the Cenozoic. Mammals, man the Ice Age and and great lakes were created in this era.
