Dinosaurs became extinct 65 million years ago, after living on earth for a staggering 165 million years, foreshadowing the growth of larger mammals and the rise of the human race.

Within the first five million years of the Paleocene Epoch, largeĀ  mammals had appeared for the first time. Some of them were the earliestĀ  members of modern groups, including primitive carnivoransĀ and ungulates.Ā  The first primates (members of the mammalian order that includesĀ  humans) appeared about 10 million years after the K/T boundary event.Ā  Modern bird groups diversified as well, in the absence ofĀ pterosaursĀ  (which had also gone extinct). Perhaps without the extinction ofĀ  the dinosaurs, the evolution ofĀ mammals and the subsequent riseĀ  of humans would have never happened. And although recent historyĀ  might well be called the Human Age, the time that the human raceĀ  has dominated planet Earth is but a blink in geologic terms.

They say that the biggest mammals that lived during the reign of the dinosaurs weighed no more that 10 KG. I assume this was because they were the bottom of the food chain so time to grow and develop was very limited.

I know there are lots of different theories about how the world began and how the human race evolved. What fascinates me the most is all the wonderful amazing things that helped create this world, before I was part of it. I really wish I hadĀ decided to be a historian, when I was growing up.
