Description: Giganotosaurus is a carcharodontosaurid theropod from Patagonia that approached tyrannosaurids in mass while retaining a longer, narrower skull with laterally compressed, serrated teeth reminiscent of sharks. This dental morphology targeted deep lacerations in large sauropod hide. Pack hunting remains hypothetical but is debated in light of multiple individuals recovered from single horizons.

Features:
  - Skull length approaches ~1.8 m in large adults
  - Denticles along carinae form a saw-like cutting edge
  - Predates Tyrannosaurus by roughly thirty million years

Related genera: Mapusaurus, Tyrannotitan, Carcharodontosaurus
