Figure 3. Cenozoic CO 2 atmospheric mixing ratio and seawater partial pressure. Notice the huge difference between atmospheric CO 2 and pCO 2.Also notice that pCO 2 was higher before and after the PETM and that stomata data indicate that CO 2 was about what it is today, apart from a short duration spike to about 800 ppmv 55.2 Mya. Talk about settled science!

The era that began with the demise of the dinosaurs and the rise of "recent" species and continues to the present; it also is known as the Tertiary. Compare Paleozoic , Mesozoic .

McKenna and Farrell ( 5) present two main conclusions regarding diversification rates in Cephaloleia. First, they infer an across-clade slowdown in rate over time. Second, they localize the most significant shifts in diversification rate to the Eocene, with some additional shifts in the Oligocene in nested clades arising ...The Cenozoic Era is the most recent of the four major divisions in animal history.

Of course, just like we divide up the year into months, weeks, and days, geologists divide the history of Earth into several different time periods. The longest time period geologists use is called an "eon." Eons are divided into shorter time periods called "eras," and eras are divided into even shorter times called "periods."

This terrifying predator, with 7 inch long teeth, used to eat whales. The Megalodon was not the only giant shark found in the oceans during the cenozoic era, another shark the Otodus grew to a staggering 39 feet in length, twice the length of the biggest great white sharks.
