Giganotosaurus, which means "giant southern lizard," was a large dinosaur species that lived in South America during the early Cenomanian stage of the Late Cretaceous Period, 100 to 96 million years ago, and about 30 million years before T. rex.
Giganotosaurus is a member of the Carcharodontosauridae family. There is only one known species of the dinosaur: Giganotosaurus Carolinii. Giganotosaurus has a strong bite force, extremely fast speed, and sharp teeth like steel knives, and its attack power is second only to the Tyrannosaurus rex.
First described in a 1995 study(opens in new tab) in the journal Nature, Giganotosaurus was, at the time, thought to be the largest carnivorous dinosaur. With the discovery of more fossils and advanced dynamic restoration technology, people have learned more about Giganotosaurus.
In 1993, archaeologist Ruben d. Carolina accidentally discovered a terrifying monster that existed in ancient times during archaeological excavations in the Patagonian plains of Argentina. This terrifying beast is the second-largest biped ever on Earth. In 1995, the dinosaur was named Giganotosaurus.
Giganotosaurus was a large carnivorous dinosaur with a large head and a huge mouth with sharp teeth. Giganotosaurus had a strong set of bones to support their massive size, and their tails were pointed, slender, and long. One of the key factors that made Giganotosaurus a good predator was its teeth, which were up to 20 cm long and were stout dagger-shaped. Paleontologists believe that such tooth structures are ideal for biting and crunching bones. Giganotosaurus has very short forelimbs, thick hind limbs, and sharp claws or claws on the limbs. Giganotosaurus could run an estimated 31 mph (59kph).
Calculating mass from fossils is notoriously difficult. Giganotosaurus is the largest terrestrial carnivore and the largest carnivorous dinosaur in the history of South America, and the second largest carnivorous dinosaur in history. The biologists analyzed and estimated that Giganotosaurus was up to 40-46 feet long (12.2-13 m) from head to tail, 23 feet high, and weighed up to 14 tons.
|Period||Lived 100 to 96 mya in South America||Lived 112-97 mya in North Africa||Lived 67 to 65 mya in North America and Mongolia|
|Length||40-46 feet long (12.2-13 m)||At least 50 feet long||40 feet long|
|Weight||up to 14 tons||up to 23 tons||up to 9 tons|
|Appearance||Huge skull with sharp teeth; short arms and three-fingered||Long spines on back; long, narrow snout; powerful jaws with needle-like teeth||Strong back legs; tiny forearms; massive, thick skull; powerful jaws with serrated teeth|
The discovery of Giganotosaurus fossils is an important archaeological sensation because the theropod is not trivial in size, and it is also the longest carnivorous dinosaur femur ever found. There are few types of dinosaurs discovered by humans in the southern hemisphere, while Giganotosaurus is the largest predator in the local area. It has no rivals that can compete with it and is at the top of the food chain.
