Are Tyrannosauri to become racist?

If our planet does survive that long, many millennia from now, when alien life forms - or even dominant species on Earth at that time - discover the bones of extinct chimpanzees, humans and bonobos, all primates under the rubric of 'Great Apes', the investigators could be liable to think that all three were members of the same species. The two species of the genus Pan would likely find this scenario demeaning, considering the species of the genus Homo may well be responsible for the demise of all three. It turns out that - for obvious reasons, only posthumously - there may be a similar reaction among the dinosaur we know as the Tyrannosaurus rex. Palaeontologists now think that T rex was not one species but three. How this could amount to racism among dinosaurs is not a question that needs to be answered.

The scientists studying the remains of the extinct predator(s) figure that the bone structures or 'robustness' varied not between individual T rexes but between the T rex, the T   imperator and T regina. Also, the number of lower teeth vary, which may not be attributable to individual oral hygiene practices. If, indeed, this turns out to be true, political correctness would suggest equal representation in popular culture for T imperator and T regina - even though T rex is still the easiest to utter on our teeth.
