The Precambrian (or Pre-Cambrian, sometimes abbreviated pЄ, or Cryptozoic) is the earliest part of Earth's history, set before the current Phanerozoic Eon.

The Precambrian is so named because it preceded the Cambrian, the first period of the Phanerozoic eon, which is named after Cambria, the Latinised name for Wales, where rocks from this age were first studied.

The Precambrian represents more than 80 percent of the total geologic record. Precambrian - Precambrian - Precambrian life: Precambrian rocks were originally defined to predate the Cambrian Period and therefore all life, although the term Proterozoic was later coined from the Greek for “early life.” It is now known that Precambrian rocks contain evidence of the very beginnings of life on Earth—which, based on the age of the rocks that contain the oldest evidence.

The Precambrian ( to million years ago) is a vast period of time, nearly 4, million years long, that began with the formation of the Earth and culminated with the Cambrian Explosion.

The Precambrian accounts for seven-eighths of our planet's history. About this book. The motivation for this volume came from the idea that the Precambrian is the key, both to the present, and to the understanding of the Earth as a whole. The Precambrian constitutes about 85% of Earth's history, and of that, about billion years of Precambrian time, represented by rocks, are accessible to geoscientists.

Precambrian definition is - of, relating to, or being the earliest era of geological history or the corresponding system of rocks that is characterized especially by the appearance of single-celled organisms and is equivalent to the Archean and Proterozoic eons.

Precambrian time covers the vast bulk of the Earth's history, starting with the planet's creation about billion years ago and ending with the emergence of complex, multicelled life-forms. The term “Precambrian” is the name that refers to the 4 billion years before hard bodied animals that we see around us today, were even born.
