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! For example, the Cenozoic Era began about 65.5 million years ago and continues to the present day. This means that the Cenozoic Era is about 1% of the total geologic time scale, but it is also the only era that is still ongoing.
