No. The Cenzoic Era is the current era.
What length of time does the geological time scale cover?
There is no definite length of a geological time scale, unless you wish to use some 13 billion years which the universe has existed for. The geological time scale tends to use the units of time: 109 (billion) years, and 106 (million) years. E.g. the Earth is 4.6 billion years old; the Carboniferous period was around 350 million years ago. The scale is greatly varied. If you were to plot all major events, you might consider making your scale logarithmic, especially if you were planning to put the appearance of Homo Sapiens (us) on the same scale as the formation of the Solar System.
How old was earth when life appeared on it?
The Earth is about 4.5 billion years old. Life appeared on Earth about 3.5 billion years ago. The Earth would have been about 1 billion years old at that time.
when was the era of geologic time was the longest?
The Precambrian ... about 3 billion years.
The epoch spans the time between 65 million and 56 million years ago?
Paleocene
The Archean Eon spans the time from the formation of the Earth until years ago?
2.5 billion years ago
What length of time is covered by the geologic time scale?

How long did the precambrian last?
There is some debate among experts, but it is generally accepted that the Precambrian lasted from 3.9 to 4 billion years. This time period is made up of three eras which are the Paleoproterozoic, the Mesoproterozoic, and the Neoproterozoic era.
What era was earth first formed Cenozoic Mesozoic Paleozoic or Precambrian PLEASE HELP?
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.
How many decades have there been?
Scientists believe that about 13.7 billion years have passed since the beginning of time. 13.7 billion years is 1.37 billion decades.
Is earth 4.8 years old?
The Earth is 4.6 billion years old, give or take a hundred million years. It has been habitable for almost 4.5 billion years. The Earth and the Sun and other planets formed at the same time, give or take a hundred million years. The Universe is much older, over 13 billion years.
About 85 percent of geologic time is represented by the time span called?
PrecambrianThis period is also split into two Eons: Archean (from 2.5 billion to 4.5 billion years ago) and Proterozoic (from 542 million to 2.5 billion years ago).
What is million and billion?
One billion = 1,000,000,000 One million = 1,000,000
How does deep time differ from human time?
Divide 10^6 ( a million years ) by an average U.S. life span, ~75 years. 10^6/75 = 13,333 life spans. That is the incomprehensible difference between deep time and ' human time. '
What is the equivalent of 1 million years in biblical time?
In biblical time, there isn't an exact equivalent measurement for 1 million years. The Bible does not provide a specific timeframe or conversion for this length of time. It primarily focuses on the history of humanity and the relationship between God and humankind, rather than providing detailed time measurements.
Is 1 million years still young for a planet?
One million years, in astronomical terms is a short period of time. Models of star development dates our solar system at around 5 billion years; this ties in with radioactive dating of meteorites and moon rock samples which dates them at 4.5 billion years.
