Different life forms for each era.
Precambrian, microscopic life.
Paleozoic-sea worms
Mesozoic-trilobytes
cenozoic-horseshoe crabs
The dominant geologic events in the first two was the lack of land masses.

precambrian, formation of eart tectonic plates arose and started to move and arose life: eukaryic cells and first animals
paleozoic, explosion, animal phyla fungi plants and insects aka period of incursions of continents
mesozoic, middle animals. dino's birds angiosperms and cycads
mass extinction
cenozoic, present day, flowering plants insects fish birds mammels......
