20 Giganotosaurus Questions and Answers

Bigger, more teeth, and longer, the giganotosaurus was a huge predator that was likely longer than Tyrannosaurus Rex. Only recently ( for a dinosaur) discovered in argentina it would have hunted sauropods and long necked dinosaurs for food. Possibly in packs.

Giganotosaurus was the apex predator of its era, growing up to 40 ft long, weighing 20,000 lbs or more it was one of the largest carnivorous dinosaurs ever. It had shark like teeth and therefore belonged to the Carcharodontosaurid family of dinosaurs and was discovered in 1993 in Argentina.

With it being more recent and with a lack of fossils to learn from means there is still so much to learn about the giganotosaurus, but we have some questions and answers below covering what we do know about this shark toothed dinosaur.

How fast was the Giganotosaurus?

The giganotosaurus had incredibly strong legs and before 2017 it was thought it might be quite a fast runner. However, a study in 2017 on T-Rex suggested these dinosaurs were so big that it would be difficult to run fast without causing damage to bones.

This study suggested this would be the case for most large carnivorous dangerous like Giganotosaurus, Mapusaurus and others. Another study then suggested that the long heavy tail would have allowed it to run reasonaly fast. SO the simple answer is …. we don’t know!

If the giganotosaurus was a fast and agile runner, it is estimated to have been able to run at about 30 miles and hour or 50km per hour. However as we mentioned above this is not agreed by scientists.

Some of My Dinosaur Resource Recommendations for Home and School.

Thanks for taking the time to read our facts and questions articles, as a teacher myself i have struggled to find resources in one place and that is why this website was born. I simply love teaching students about dinosaurs both in my role as a language and General Studies teacher. However there is sometimes a need for something more concrete than a printout (as useful as we think ours are! )

There is something awesome about the feeling of awe that these amazing creatures instil in our children and students. To further help you, and potentially me, i have included a few resources below that i have found to be incredibly successful when explaining dinosaurs to children, these range form books and resources, to toys fossils and dinosaur figures.

Sometimes having something tactile to touch in those tiny hands help to focus and cement learning and develop those big brains! Hope they are helpful too.

Dinosaur Books and Readers

There are of course hundreds of excellent, and not so excellent books on Dinosaurs for Children out there. So rather than, yet, go into huge detail. I will highlight the ones I love to use with my students from ages 6 to 10. We have include AR in these as well. ( nothing quite like a moving dinosaur in front of you!

Fossil Sets

I cant say how great these are to use in a classroom while reading with a group. the chance to read about a dinosaur and then touch a real piece is simply great. I have a selection ( self confessed dinosaur geek) but a cheap set of 10 or so will do the trick just as well. Dinosaur poop is great as well!!! i pass it round and ask them to guess what it is first!

Dinosaur Figures

I actually use realia in a lot of classes especially with animals and dinosaurs, and figures help to show the kind of animal we are reading about. It is possible to spend hundreds of dollars on dinosaur figures but there is no need, either as a teacher or a parent. The set below and similar we have used to help students picture dinosaurs to great effect.
