Ankylosaurus Facts For Children

Ankylosaurus must have been quite a find on the day they uncovered that 2 and a half foot long and wide skull. Almost solid bone it is easy to see why it got its name. Ankylosaurus means fused lizard as its bones are all very solidly connected to each other. There are plenty of facts about this dinosaur we know and we have highlighted the best ankylosaurus facts for kids in the article below.

Although ankylosaurus was a herbivore and probably prey for the large carnivores it lived with we are sure that it wasn’t the first choice for the carnivorous like Tyrannosaurus rex. The huge size, the armoured back, horned head and 2 ft long solid bone club on its tail shows how seriously this dinosaur took its defense. Let take a look at that armour and its club in our ankylosaurus facts below.

3. Ankylosaurus was a large dinosaur, its length could be up to 27ft (8 meters) and its weight was about 15000 lb (8000 kilograms). All that armour would have added to the weight!

7. Ankylosaurus armor was made of bony plates and spikes that protected it from predators. These bony plates, called scutes, covered nearly all the back and would have been used to try to stop dinosaur teeth from causing damage. Crocodiles have similar scutes on their bodies as well.

8. These bony plates and spikes could be various sizes and were from half an inch (1cm) to 14 inches in length (35cm)

9. Ankylosaurus had about 72 teeth in its mouth. these were shaped like leaves and like other herbivore dinosaurs could be replaced when they were worn out. In fact fossils have been found with both the old teeth and the new teeth.

We hope you have learnt a few more facts about the armored walking tank of a dinosaur from our ankylosaurus facts pages. it really was a incredible dinosaur and not an easy meal for any predator no matter how big they were.

Its 14 inch armoured plates, 2ft long and wide club on the ends of its tail would help it put up a fight against even a hungry tyrannosaur. There were other armoured dinosaurs in its family but this was the biggest and in our opinion the best.

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! )

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.
