The Paleozoic era was from 540 million years ago to about 245 million years ago. After that came the Mesozoic era, and that lasted from the end of the Paleozoic to 65 million years ago, when the earth entered the Cenozoic era.
The Paleozoic, the Mesozoic and the Cenozoic are the 3 Eras of the Phanerozoic Eon.The Paleozoic Era occurred between 542 and 251 million years ago. It lasted 291 million years. It was made up of 6 geological periods. The Cambrian Period(542 - 488Ma), the Ordovician(488 - 443Ma), the Silurian(433 - 416Ma), the Devonian(416 - 359Ma), the Carboniferous(359 - 299Ma) and the Permian(299 - 251Ma).The Mesozoic Era occurred between 251 and 65.5 million years ago. It lasted 185.5 million years. It was made up of 3 geological periods. The Triassic Period (251 - 199.6Ma), the Jurassic(199.6 - 145.5Ma) and the Cretaceous(145.5Ma).The Cenozoic Era occurred between 65.5 million years ago to now. It has lasted 65.5 million years to date. It has been made up of 3 geological periods to date. The Paleogene(65.5 - 23.03Ma), the Neogene(23.03 - 2.588Ma) and the current period the Quaternary Period (2.588Ma - Now)
The major subdivisions are the Precambrian, Palaeozoic, Mesozoic and Cenozoic, which are subdivided into Archean and Proterozoic (Precambrian), Cambrian, Ordovician, Silurian, Devonian, Carboniferous (or Missisipian and Pennsylvanian in the US) and Permian (Palaeozoic), Triassic, Jurassic and Cretaceous (Mesozoic) and Tertiary and Quaternary (Cenozoic).

The term "lute" refers to an old stringed instrument. It was popular from the Medieval to the Baroque eras, and was an extremely important instrument in secular music during the Renaissance.

The geological eras are divided into four main eras: Precambrian, Paleozoic, Mesozoic, and Cenozoic. Each era represents a significant period in Earth's history characterized by distinct geological and biological events. These eras help scientists understand the evolutionary history and changes that have occurred on our planet over millions of years.
The 4 eras are Cenozoic era, the mesozoic era, the paleozoic era, and the precambrian era.
Four. Precambrian, Paleozoic, Mesozoic, Cenozoic.
Precambrian Era Paleozoic Era Mesozoic Era Cenozoic Era
The three eras of geologic time are the Paleozoic, Mesozoic, and Cenozoic eras. The Paleozoic era is known for the development of marine life, the Mesozoic era is often referred to as the "Age of Dinosaurs," and the Cenozoic era is characterized by the diversification of mammals and the rise of humans.
The geologic time scale is divided into four eras: the Precambrian, Paleozoic, Mesozoic, and Cenozoic eras. Each era represents a distinct span of time in Earth's history with characteristic geological and biological features.
Pangaea, the supercontinent, was formed during the late Paleozoic and early Mesozoic eras, specifically around 300-200 million years ago. It existed during the late Paleozoic and early Mesozoic eras before breaking apart into the continents we recognize today.
Precambrian, Paleozoic, Mesozoic, and Cenozoic.
Paleozoic and Mesozoic eras about 250 million years ago
The Eras go like this: Precambrian Era Paleozoic Era Mesozoic Era Cenozoic Era Dinosaurs lived during the Mesozoic Era, and we live in the Cenozoic Era. Paleozoic means "ancient life" Mesozoic means "middle life" Cenozoic means "recent life" All eras end in a huge disaster
