Hopefully the new guy will have his own Twitter account too.
For more than 17 years, Sue the Tyrannosaurus rex has reigned supreme at Chicago's Field Museum.
In the past few years she's even built up an online reputation as being one of the best accounts to follow on Twitter, provided you love memes and puns (and who doesn't?).
In 2018, however, Sue is getting some competition. Massive competition.
In 2014, the world got a look at a behemoth dinosaur known as the "titanosaur" when it was discovered in Argentina. Now, it's making its way to Sue's home in the Windy City.
