How Many Humans Would a Tyrannosaur Rex Need to Eat Each Day to Survive? by xkcd

xkcd on T-Rex Metabolism

In the latest installment of what if?, xkcd addresses a reader question about Tyrannosaurus rex metabolism: “If a T-rex were released in New York City, how many humans per day would it need to consume to get its needed calorie intake?” According to xkcd, a T. rex would need to eat half a human per day (or a human every two days). At this rate, the population of New York City could sustain about 1,000 Tyrannosaurs.
