15 Roar-some Facts About The Mapusaurus That Kids Will Love

Discover interesting Theropoda Mapusaurus facts!

The Mapusarus was a huge Carcharodontosaurid carnosaurian dinosaur from the early Late Cretaceous period. It belonged to the phylum Chordata, the family Carcharodontosauridae, and the tribe Giganotosaurini. It was discovered all at once at an excavation in South America in 1995. The bones of different Mapusaurus dinosaurs were discovered together of different age groups and this acts as evidence of the herding and social behavior of this dinosaur. They might have hunted together in a small pack to catch huge dinosaurs like the Titanosaurus that inhabited the same area. According to the study of their teeth, it has come to light that these dinosaurs might have preyed on large dinosaurs like the Argentinosaurus. A paleontologist, Philip Currie from the University of Alberta, said that the Mapusaurus might be the biggest carnivorous dinosaur in history. They were bigger than the Tyrannosaurus.

Comparison with similar dinosaurs

Mapusaurus vs. T rex: The Mapusaurus had a very light, narrow, and long skull which was not as strong and powerful as that of a Tyrannosaurus rex skull. Though the Mapusaurus had more teeth in its jaw, they were thinner and narrower than the Tyrannosaurus rex’s teeth. The bite of a Tyrannosaurus rex was much more fatal than that of a Mapusaurus, even though the former’s teeth were sharper. The Tyrannosaurus rex was also smaller in size than the Mapusaurus.

Mapusaurus vs Giganotosaurus: The Giganotosaurus and Mapusaurus were very similar to each other but the Mapusaurus size was bigger by a small margin than the Giganotosaurus. The Mapusaurus had just three bones, and all of them were bigger than those of the Giganotosaurus. The skull of a Giganotosaurus was slimmer, but the weight was slightly more. The body build of the Mapusaurus was better.
