> \*\*In Michael Crichton’s The Lost World, he talks about the Tyrannosaurs as having that reverse sexual dimorphism, because the females were so much larger than their male counterparts. I don’t know if that’s true, but it’s the first thing that popped into my head. \*\*

The problem with Tyrannosaurs is that we have a dismally small sample size (only about two dozen specimens of _T. rex_ have been found so far) from which to work. The largest one we have to date (nicknamed “Sue”) is a female. But that does not mean that the general trend is that females were larger than males.
