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.

Detailed explanation-2: -The Quaternary Period is the third and last of the three periods of the Cenozoic Era. You and I are living in this period, which began only 2.58 million years ago.

Detailed explanation-3: -The Cenozoic Era is the “Age of Mammals.” North America’s characteristic landscapes began to develop during the Cenozoic. Birds and mammals rose in prominence after the extinction of giant reptiles. Common Cenozoic fossils include cat-like carnivores and early horses, as well as ice age woolly mammoths.

Detailed explanation-4: -Officially, the current epoch is called the Holocene, which began 11, 700 years ago after the last major ice age.

Detailed explanation-5: -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.
