Tyrannosaurus
Like other tyrannosaurids, Tyrannosaurus was a bipedal carnivore with a massive skull balanced by a long, heavy tail. Relative to the large and powerful hindlimbs, Tyrannosaurus forelimbs were small, though unusually powerful for their size, and bore two clawed digits. Although other theropods rivaled or exceeded Tyrannosaurus rex in size, it was the largest known tyrannosaurid and one of the largest known land predators, measuring up to 12.8 m (42 ft) in length, up to 4 metres (13 ft) tall at the hips, and up to 6.8 metric tons (7.5 short tons) in weight. By far the largest carnivore in its environment, Tyrannosaurus rex may have been an apex predator, preying upon hadrosaurs and ceratopsians, although some experts have suggested it was primarily a scavenger. The debate over Tyrannosaurus as apex predator or scavenger is among the longest running in paleontology.
Alamosaurus
A recent analysis has shown that Alamosaurus may have been a bigger dinosaur than originally estimated, possibly in the weight class of its more famous South American cousin Argentinosaurus. It turns out that some of the "type fossils" used to reconstruct Alamosaurus may have come from adolescents rather than full-grown adults, meaning that this titanosaur may well have attained lengths of over 60 feet from head to tail and weights in excess of 70 or 80 tons.
