Was the tyrannosaurus rex the biggest dinosaur?

Answer 1

Tyrannosaurus Rex was one of the biggest carnivorous dinosaurs, but no, Spinosaurus Aegyptiacus is the longest known carnivore (by about 5 ft). Spinosaurus, however, weighed only up to 4 1/2 tons whereas T. Rex weighed up to 7 1/2. Other Tyrannosaurs have also been found that may have been bigger than both T. Rex and S. Aegyptiacus, but there are not enough specimens of these species as of yet to make an accurate measurement. Argentinasaurus, however, is possibly the largest dinosaur known to man, weighing an estimated 73 tons and with a length of about 30 meters (Possibly longer than the Blue Whale).

In terms of size in dinosaurs it is customary to use the length or erect height of the animals, but the weight is often unjustly discounted. In terms of weight the Tyrannosaurs are the largest theropods and as a result in life they probably would have looked 'bigger' than S. Aegyptiacus, though neither of them were anywhere near as heavy, or as long, as most of the giant suaropods (Argentinasaurus included). Also, in terms weight no animal has ever come close to the size of the blue whale, its whopping 180 metric ton average weight approached only by other whales.
