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: -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!
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.
