Detailed explanation-1: -Cenozoic (66 million years ago until today) means ‘recent life. ‘ During this era, plants and animals look most like those on Earth today. Periods of the Cenozoic Era are split into even smaller parts known as Epochs, so you will see even more signposts in this Era.

Detailed explanation-2: -The Cenozoic is sometimes called the Age of Mammals, because the largest land animals have been mammals during that time. This is a misnomer for several reasons. First, the history of mammals began long before the Cenozoic began. Second, the diversity of life during the Cenozoic is far wider than mammals.

Detailed explanation-3: -Age of Mammals. The Cenozoic Era, from 65 million years ago to today, is the age of mammals and flowering plants and is marked by global cooling. The extinction of the dinosaurs allowed mammals to diversify and grow in size during the Cenozoic.

Detailed explanation-4: -From the extinction of the dinosaurs until today, the Cenozoic Era is the age of mammals. Mass extinctions create opportunities for new life to thrive, and mammals filled the gap that dinosaurs left behind. They evolved into many species you would recognize today-including humans!
