Some of my top picks:
Titanoboa, the biggest known snake to ever live
Giant Moa, which survived as recently as the 1500s
Thylacine/Tasmanian Tiger, survived until the 20th century
Woolly Rhinoceros, a resident of the more recent Ice Ages
Basilosaurus, a predatory whale 15-18 meters long
Bet with Liquidlaser: I say PS5 and Xbox Series will sell more than 56 million combined by the end of 2023.
