Precambrian
The Carboniferous period lasted 73 million years. It was the longest period in the Paleozoic era.
i think the answer is precambran...but im not quite sure.
So far, the Tertiary period of the Cenezoic Era has been the longest. We are currently in the Quaternary period of the Cenezoic Era.

The earliest geological period is known as the Precambrian. This is a very long period of time which begins about four and a half billion years ago, with the formation of the Earth, ending at the beginning of the Cambrian Era which is about 541 million years ago. So the Precambrian is about four billion years long, longer than all other eras combined.
The Longest Era of Earths History is Paleoproterozoic Eralasting 900 million years.The largest unit of time in relation to Earth's history is the super-eon. Super-eons are divided into eons. Eons in turn are divided into eras, eras are divided into periods, periods into Epochs and Epochs in Ages.Precambrian Super-Eon (4,600 - 542 Ma)Hadean Eon (4,600 - 3,800 Ma)Archean Eon (3,800 - 2,500 Ma)Eoarchean Era (3,800 - 3,600 Ma)Paleoarchean Era (3,600 - 3,200 Ma)Mesoarchean Era (3,200 - 2,800 Ma)Neoarchean Era (2,800 - 2,500 Ma)Proterozoic Eon (2,500 - 542 Ma)Paleoproterozoic Era (2,500 - 1,600 Ma)Mesoproterozoic Era (1,600 - 1,000 Ma)Neoproterozoic Era (1,000 - 542 Ma)Modern Super-Eon (542 Ma - Now)Phanerozoic Eon (542 Ma - now)Paleozoic Era (542 -251 Ma)Mezozoic Era (251 - 65 Ma)Cenozoic Era (65 Ma - Now)
The Precambrian Super-Eon is the informal name for the time on earth before the Cambrian Period. It lasted from 4,576 millions years ago until 542 million years ago, about 4.034 billion years.No geological era lasted as long. The longest era was the Paleoproterozic Era(2,500 - 1,600Ma) which lasted 900 million years.
tortoise has lived the longest
The longest necklace is about 355 feet.
The Precambrian era is the longest geological era, spanning from about 4.6 billion years ago to 541 million years ago, but it is also the era with the least amount of detailed information available due to the lack of well-preserved rocks and fossils from that time period.

It was the Precambrian time period.

The Precambrian time period is the longest time period of Earth's history.Looks like we have the same worksheet in school :)
The answer is NOOOO!!!! It is not the longest Era!!! The Precambrian consisted of the Archean and Proterozoic Eras which each pull roughly 2 billion years of geologic time making up the first 4 billion years of Earth. The Archean from 4.5 Billion Years Ago to about 2.5 BYA and the Proterozoic from 2.5 BYA to about 570 MYA. The Paleozoic which preceded the Mesozoic lasted about 345 Million years (570 MYA- 225 MYA) and the Mesozoic lasted about 215 Million years (225 MYA- 65 MYA).
Precambrian Era.
precambrian times
The Precambrian ... about 3 billion years.
The Precambrian. Hope this helps! :)
The Hadian Eon (4576.2 to 4000 Million years) has not been subdivided into recognised Era's. The named Era's from oldest to newest are. Eoarchean Era (4,000 to 3,600 Ma) Paleoarchean Era (3,600 to 3,200 Ma) Mesoarchean Era (3,200 to 2,800 Ma) Neoarchean Era (2,800 to 2,500 Ma) Paleoproterozoic Era (2,500 to 1,600 Ma) Mesoproterozoic Era (1,600 to 1,000 Ma) Neoproterozoic Era (1,000 to 542 Ma) Paleozoic Era (542 to 251 Ma) Mesozoic Era (251 to 65.5 Ma) Cenozoic Era (65.5 Ma to Now)
The period of Earth's time that would be considered longest is the Precambrian Era.
