The Paleozoic Era was the second in geological time. It was between 541 to 251 million years ago. Phyla, fish, arthropods reptiles and amphibians all evolved during the Paleozoic era. The end of the Paleozoic period ended with the largest mass extinction in history.
Darwin witnessed various geological phenomena and formations during his travels, including volcanic eruptions, uplifted coral reefs, and fossil evidence of past life forms. These observations played a significant role in shaping his understanding of geological processes and the concept of deep time.
The four eras of geologic time are the Precambrian, Paleozoic, Mesozoic, and Cenozoic. These eras represent significant periods in Earth's history, each characterized by distinct geological and biological events.
The budget of the Geological Survey of Canada is determined annually by the Canadian government and can vary from year to year. Specific budget information can be found in the organization's annual reports or by contacting their financial department directly.

The Precambrian is the geological era about which we have the least information, as it covers an extensive period of time from the formation of the Earth to the beginning of the Paleozoic era, and much of the evidence from this era has been altered or eroded over time.
Precambrian.
The era that is divided into smaller units of time scale is the "Geological Era." Geological eras are major subdivisions of geological time and are further divided into periods, epochs, and ages, allowing scientists to study Earth's history in more detail. The three primary geological eras are the Paleozoic, Mesozoic, and Cenozoic, each encompassing significant events in the planet's evolutionary history.

The Cenozoic era
No, the Mesozoic Era is not the first geological era. It is the era that followed the Paleozoic Era and preceded the Cenozoic Era in Earth's history. The Mesozoic Era is known for the age of the dinosaurs and lasted from about 252 million years ago to 66 million years ago.
