Which geological time period is referred to as the "ancient" time, notable for the presence of Gondwana?

The Paleozoic Era is often referred to as the "ancient" time in geology because it is one of the earliest major divisions of Earth's history, spanning approximately from 541 to 252 million years ago. This era is characterized by significant geological and biological developments, including the formation of the supercontinent Gondwana. During the Paleozoic, Gondwana was a vast landmass that included present-day continents such as South America, Africa, Antarctica, and Australia. The era witnessed the emergence of diverse marine life, the colonization of land by plants and animals, and the eventual rise of more complex organisms.

In contrast, the Mesozoic Era is known for the dominance of dinosaurs and the breakup of Pangaea, the earlier supercontinent that included Gondwana. The Cenozoic Era follows the Mesozoic and is often referred to as the "Age of Mammals" after the extinction of the dinosaurs. The Precambrian encompasses a much longer and earlier period which predates the Paleozoic and is known primarily for the development of simple life forms, making it less specifically associated with Gondwana's notable presence. Therefore, choosing the Paleozoic Era directly connects to the concept of ancient geological times as well as
