T-rexes

T-rex is a word used to describe the prehistoric animals of the Tyrannosaurus genus (though treated as a species by many), and the cultural depictions based on it thereof. The T-rex is named after Tyrannosaurus rex, which is just one species of Tyrannosaurus that scientists have proclaimed. Nonetheless like all dinosaurs, T-rexes are thought of as a one-species-one-race-one-genus sort of deal, except when it's important to depict it otherwise, such as with this article. Sometimes other animals similar to them get mistakenly called T-rexes, like Tarbosauruses and Allosauruses. T-rexes are one of the most popular dinosaurs, appearing in most dinosaur films. And when it doesn't appear, often a T-rex like animal is depicted to take its place (such as those previously mentioned). 
T-rexes themselves represent the huge, mindless, gluttonous violence of a predator. It is monster-like, dragon-like. Not so much creepy as it is threatening, intimidating, and voracious. Sometimes this trope is subverted by making T-rexes smart or vegetarian, often in an in-your-face sort of way. They are sometimes made fun of by the audience for their tiny arms, which in real life "would not be possible to clap with them, due to their sheer size".
