‘End of the Megafauna’ examines why so many giant Ice Age animals went extinct

- New book's colorful illustrations also offer perspective of just how large these creatures were!


Something that probably happened 50,000 years ago: A large 'goanna dragon' snaps at a too-rotund wallaby, who had only itself to blame.  All the other wallabies got away, and survived the vanquished lizard.

End of the Megafauna
Ross D.E. MacPhee and Peter Schouten (illustrator)
W.W. Norton & Co., $35

Today’s land animals are a bunch of runts compared with creatures from the not-too-distant past. Beasts as big as elephants, gorillas and bears were once much more common around the world. Then, seemingly suddenly, hundreds of big species, including the woolly mammoth, the giant ground sloth and a lizard weighing as much as half a ton, disappeared. In End of the Megafauna, paleomammalogist Ross MacPhee makes one thing clear: The science on what caused the extinctions of these megafauna — animals larger than 44 kilograms, or about 100 pounds — is far from settled.

MacPhee dissects the evidence behind two main ideas: that as humans moved into new parts of the world over the last 50,000 years, people hunted the critters into oblivion, or that changes in climate left the animals too vulnerable to survive. As MacPhee shows, neither scenario matches all of the available data.

Throughout, Peter Schouten’s illustrations, reminiscent of paintings that enliven natural history museums, bring the behemoths back to life. At times, MacPhee slips in too many technical terms. But overall, he offers readers an informative, up-to-date overview of a fascinating period in Earth’s history.
