The correct order of the four major geologic eras from oldest to most recent is Precambrian, Paleozoic, Mesozoic, and Cenozoic.
The geologic time scale is arranged from the time of Earth's formation through modern day. It is arranged into four eras. Those eras are Precambrian, Paleozoic, Mesozoic, and Cenozoic. Those eras are divided into periods in which the development of various life forms occurred.
The 4 eras are Cenozoic era, the mesozoic era, the paleozoic era, and the precambrian era.
The order of geologic time from smallest to largest is Phanerozoic, Proterozoic, Archean and Hadean (Deep Time). These four periods are called Eons which can be further subdivided into Eras, Periods and Epochs. Most people are more familiar with the periods such as Cambrian, Permian, Triassic, Jurassic and. Cretaceous and many more to numerous to mention. To learn more, Google geologic time scale.
The Geologic Time Scale is divided up by four major intervals. In order from Largest to smallest: Eons are the largest time frame covering hundreds of millions of years. Eons are divided into smaller time intervals known as Eras. Eras are subdivided into Periods. Periods are broken into finer subdivisions known as Epochs.

Four eons comprise Earth's geological time scale. Other time intervals of the Earth are eras, periods, and epochs.
