Hybrid Librarian continues its quest for the largest animals to ever roam the planet, such as Gigantopithecus, the largest ape. Gigantopithecus came on the scene 5 million years ago in the bamboo forests of China and India. The animal stood 10-feet-tall and disappeared nearly 100,000 years ago, but many believe it didn’t go completely extinct. There are nine other new animals featured in Hybrid Librarian’s World’s 10 Biggest Animals of All Time, Part II.
