## Step1<br />The Cenozoic Era, also known as the "Age of Mammals", is the most recent of the three major subdivisions of the Phanerozoic Eon. This era began approximately 65 million years ago and continues to the present day. The term "Cenozoic" is derived from the Greek words "kainos" (new) and "zoe" (life), meaning "new life". This era is characterized by the dominance of mammals on Earth, following the extinction of the dinosaurs at the end of the Mesozoic Era.<br /><br />## Step2<br />Pangaea was a supercontinent that existed approximately 335 to 175 million years ago during the late Paleozoic and early Mesozoic eras. It was a massive landmass that consisted of all the Earth's continents joined together. Pangaea began to break apart about 175 million years ago, leading to the formation of the continents as we know them today. The term "Pangaea" comes from the Ancient Greek words "pan" (all) and "gaia" (Earth), meaning "all Earth". It was not a mass extinction event, nor was it the southern or northern portion of a supercontinent. Instead, it was the entire supercontinent itself.
