The four large sections on the geologic time scale are eons, eras, periods, and epochs. Each of these divisions represents a different scale of time with eons being the largest and epochs being the smallest.
The earth first formed at the beginning of the Precambrian supereon which spans a very large period of time from 4,567 million years ago, through to 542 million years ago.The beginning of the Precambrian where Earth formed is known as the Hadean eon, stretching from 4.7 Ga (billion years ago) and ended roughly 3.8 billion years ago.
During the Paleozoic era, the supercontinent Pangaea began to form, leading to extensive glaciation and high sea levels. The continents were mostly located in the southern hemisphere, with vast tropical seas occupying large parts of the northern hemisphere. The land was dominated by shallow seas, swamps, and diverse marine life.
The large nation located approximately 1,200 miles north of Almaty (formerly Alma-Ata), Kazakhstan, is Russia. This distance places it well within the vast expanse of Siberia, which is part of northern Russia. The geographical proximity highlights the significant border and historical ties between Kazakhstan and Russia.

Precambrian would have been dominant because there were so many of them. They lived in very large groups in that were known as stromatolites which were reef like in many ways.

The Precambrian is the informal name for the large expanse of time preceding the current Phanerozoic Eon. It began with the Earth's formation about 4.5 billion years ago and lasted until the advent of multicellular life about 542 million years ago. Overall the planetary environment was drastically different. Life appeared sometime late in the Precambrian, but it is not known when. The Precambrian "supereon" is divided into three eons: the Hadean, Archaean, and Proterozoic. Very little is known about the Precambrian, despite the fact that it comprises nearly 90% of the Earth's history. This is simply because Precambrian rocks are so old, and are either heavily metamorphosed, have been destroyed by erosion, or remain buried deep beneath Phanerozoic strata.
