Quizplus · Accepted Answer

The Cenozoic era is the most recent of the geologic eras, covering the last 66 million years up to the present. The rocks from this era are more accessible and have not been as deformed by geological processes as those from older eras. This makes the fossil record contained within them more complete, as the fossils are easier to access, study, and are less likely to have been destroyed or heavily altered.
