List the major events of the Precambrian supereon and of thePaleozoic, Mesozoic, and Cenozoic eras`

What years was the Eocene period? Did Euprimates appear during this time?

The Permian extinction, which was the second most recent mass extinction, occurred about 251 million years ago. What is the leading hypothesis to explain the Permian extenction?     An asteroid about 6 km in diameter collided with Earth, which vaporized the caribbean ocean, set fire to north and south America, and expelled enough dust into the atmosphere to block the sun enough to result in a winter like environment all across the globe for several years     The Indian sub-continent collided with the Asian techtonic plate, giving rise to the Hymalayan mountains which altered the jet stream and caused the planet to enter an ice age     Massive amounts of volcanic activity released tons of CO2, enough to significantly increase the temperature of the planet     A new group of predators evolved that were significantly better at capturing prey, to the point that they drove many species (including other predators and eventually themselves) to extinction

Briefly describe the distinguishing organisms and major biological events of the Ediacaran period and the Paleozoic, Mesozoic, and Cenozoic eras.

What are the divisions of the geologic time scale?

In biological (paleontological) correlation, the zone created by comparing the start of the age range of one fossil, with the end of the age range of another (as shown below) is called what?  a concurrent age range zone an assemblage zone an index fossil zone a double range zone

Discuss how excess carbon dioxide lead to a mass extinction in the Permian period.
