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)

Where was precambrian era?
The Precambrian era was a geological period that spanned from about 4.6 billion years ago to around 541 million years ago. It encompasses the earliest part of Earth's history, including the formation of the planet and the evolution of life forms. The Precambrian era was followed by the Paleozoic era, which marked the beginning of complex life on Earth.

Is The Paleozoic Era the longest time period in the history of Earth.?
The Precambrian is actually the longest block (division) of time in earth geological history. But the Paleozoic era is the longest of the three "eras". The paleozoic era started about 550 million years ago and is marked by the appearance of abundant invertebrate life in the oceans. The paleozoic era ended about 225 million years ago with the forming of the supercontinent Pangaea.

What was the longest era?
The longest era in geologic time is the Precambrian era, which lasted from about 4.6 billion years ago to 541 million years ago. It encompasses about 90% of Earth's history and is divided into several eons, including the Hadean, Archean, and Proterozoic.
What is the sequence of the eras of the earth's history from the oldest to the most recent?
The sequence of the eras of Earth's history from oldest to most recent is: Precambrian, Paleozoic, Mesozoic, and Cenozoic. The Precambrian era comprises the earliest stages of Earth's formation, followed by the Paleozoic era known for the rise of complex life forms. The Mesozoic era is characterized by the age of dinosaurs, and finally, the Cenozoic era represents the current era with the dominance of mammals.
