The eon that follows the Proterozoic Eon. That part of geologic time represented by rocks in which the evidence of life is abundant.
the period from about 5,400 million years ago until the present
The period of time, also known as an eon, between the end of the Precambrian and today, The Phanerozoic begins with the start of the Cambrian period, 544 million years ago. It encompasses the period of abundant, complex life on the Earth.
(see Geological Timescale)
the eon of geologic time from 540 Ma to the present.
Period of Earth's history from 670 million years ago to present.
An eon comprising the whole of geologic time since the end of the Precambrian era, as opposed to Cryptozoic before that. It is comprised of the Paleozoic, Mesozoic, and Cenozoic eras and represented by rocks in which the evidence for life is abundant. It means ``obvious life''.
n. The geologic eon that includes the interval of time from approximately 543 million years ago to the present, comprising the Paleozoic, Mesozoic, and Cenozoic eras.
The most recent eon of geologic time beginning 543 million years ago and continuing to the present. Derived from the Greek phaneros "visible" + zoe "life".
Geologic eon that occurs from 2500 million years ago to today. During this time period, life becomes more diversified and complex.
geologic time period between 544 million years ago and present
The Phanerozoic (occasionally Phanaerozoic) Eon is the period of geologic time during which abundant animal life has existed. It covers roughly 545 million years and goes back to the time when diverse hard-shelled animals first appeared. The Phanerozoic eon is still ongoing.
