Cataclysm and Mass Extinctions

From Ancient Origins:
According to geologists, in the interval from 10,000 to 8,000 BC, some 35 to 45 species of large mammals became extinct. This is called a mass extinction . Mass extinctions can be defined as species death within a relatively short interval of time. None of the mainstream theories which attempt to account for these great extinctions are entirely satisfactory. This is likely because orthodox geologists are operating out of the straitjacket of the theory of uniformitarianism, which suggests a rather slow, gradual change over time. 
In geology, the present is key to the past. However, it’s commonly agreed that geologic time is marked by a relatively sudden change in climate about 10,000 years ago or more, from a cold glacial to warm interglacial environment. During this time, there were catastrophic changes across the planet. For example, the asphalt and tar seeps of California, like those in South America and Africa, host a rich assemblage of evidence of faunal and floral life, the most spectacular having occurred in Rancho La Brea where the remains of numerous animals are tightly packed together. 
Approximately 700 skulls of saber-toothed tigers have been systematically excavated, accompanied by a huge number of remains from horses, camels, bison, mammoths, mastodons, coyotes, wolves, sloths, and other faunal contemporaries, broken, mashed, and contorted. This suggests a sudden mass extinction where animals, predator and prey alike, were suddenly thrown together. (Read more.)

Yes, Greta, the planet is in constant flux and it did not just begin this in order to ruin your dreams.
