Giganotosaurus ("giant southern lizard") is a genus of theropod dinosaur
that lived in what is now Argentina, around 99.6 to 97 million years
ago. It was one of the largest known terrestrial carnivores, but the
exact size has been hard to determine from the incomplete remains found
so far. The holotype specimen, discovered in Patagonia in 1993, is
almost 70% complete, and indicates a length of 12 to 13 m (39 to
43 ft), a skull 1.53 to 1.80 m (5.0 to 5.9 ft) in length, and a
weight of 4.2 to 13.8 t (4.6 to 15.2 short tons). A length of 13.2 m
(43 ft) has been extrapolated from another individual's dentary bone.
Some researchers believe the animal to be larger than Tyrannosaurus,
generally considered the largest theropod. The skull was low, with a
ridge-like crest in front of the eye. The teeth were serrated, and the
front of the lower jaw was flattened. Giganotosaurus is thought to have
had a homeothermic metabolism, between that of a mammal and a reptile,
which would have enabled rapid growth but not fast movement. It was
probably the apex predator of its ecosystem, feeding on juvenile
