The geological time scale divided up and organized according to what life forms existed on earth?
The geological time scale, divided into eons, eras, periods, epochs, and ages, is organized based on key events in Earth's history, such as mass extinctions and the appearance of significant life forms. Each division represents a period when particular types of plants and animals dominated the planet, leading to the classification of geological time periods based on the fossil record and evolutionary history of life on Earth.

The Precambrian is actually the longest block (division) of time in earth geological history. But the Paleozoic era is the longest of the three "eras". The paleozoic era started about 550 million years ago and is marked by the appearance of abundant invertebrate life in the oceans. The paleozoic era ended about 225 million years ago with the forming of the supercontinent Pangaea.
