A decade later, in 1904, Henry Fairfield Osborn, an American geologist and paleontologist named this creature the Tyrannosaurus Rex. In Greek, Tyrannosaur means tyrant lizard, and Rex means the king in Latin. Like its name suggested, this creature was believed to be the biggest and most fearsome meat eater ever. It was the blood-thirsty villain and the absolute warlord of the earth in movies like the Lost World(1925), King Kong (1933), and Jurassic Park (1993). However, as new dinosaurs had been unearthed, that might have been just as deadly and even larger, the throne of T-Rex had been threatened. Out of all the carnivores, Giganotosaurus and Spinosaurus posed the most serious challenge ever to the title of the tyrant lizard king. Tyrannosaurus Rex had to try its best to prove that it was still worthy of its name.

Zoologists and ecologists like J.A. McLennan and L. Dew believed that size plays an essential role in the world of animals; predators usually try to avoid attacking similarly sized or bigger animals(). The reason behind this natural phenomenon is quite self-explanatory: bigger size provides greater strength. Dinosaurs, as members of the animal kingdom, also obey this law. Up until now, the largest T-Rex skeleton yet discovered was measured 12.8 metres (42 ft) long, and was 4.0 metres (13.1 ft) high from ground to hips (The Field Museum of Natural History). The weight of this monster, according to the latest approximation performed by Peter Makovicky, curator of dinosaurs at the Field Museum of Natural History in Chicago in 2011, was about 9 tons(Discovery News). However, this bulk did not appear very massive when standing besides ...
