20+ Brachiosaurus Questions and Answers.

Was Brachiosaurus the Largest Dinosaur?

Brachiosaurus was indeed a very large, heavy, long-necked dinosaur, and was thought to be the biggest for many years. That is until scientists discovered the Argentinosaurus and the Dreadnoughtus. (more on that on their pages!) These two dinosaurs are thought to be even bigger and even heavier than brachiosaurus.

When Did Brachiosaurus Live?

It lived about 150-157 million years ago during the Late Jurassic Period and would have lived with allosaurus, apatosaurus and other dinosaurs of that time. It may have moved in herds with smaller herbivores as well for protections, both theirs and the smaller dinosaurs.

What does Brachiosaurus Name Mean?

The name brachiosaurus literally means “arm lizard” in Latin. It was named “arm Lizard” because its front legs are longer than its hind legs. Brachio means arm and Saurus means lizard. It was given its name in 1903 three years after its discovery. However we think there are other features that make it stand out, not up, more!

How much did Brachiosaurus weigh?

Brachiosaurus was a huge, by every measure, dinosaur. Brachiosaurus probably weighed around 29 to 58 tons which is more than 116,000 lbs! It ate about 880 lbs of food every day to get to this weight! That’s a lot of food to put into a small head!

Brachiosaurus measured about 26 meters (85 feet) from head to tail, even though that is very long it was not the longest. It was thought to be the longest dinosaur ever for a lot of years but Supersaurus, recently, has been estimated to be up to 138 feet long!!

Did Brachiosaurus Live with other Dinosaurs?

Brachiosaurus did live at the same time and in the same places as other long necked dinosaurs ( sauropods), Apatosaurus and diplodocus, as well as smaller herbivore dinosaurs. To do this there must have been plenty of food for them as the brachiosaurus would have eaten the higher leaves and the others would eat lower down.

How Big was a Brachiosaurus Head?

Brachiosaurus had a small sized head relative to its body and small brain. The skull found in 1883, but attributed to brachiosaurus in 1998, was about 2.5 feet long (81 cm) but this wasn’t known for sure as, weirdly, the head was quite easy to remove from the body and rarely found. .

How Long was a Brachiosaurus Neck?

The neck of a brachiosaurus could be up to 30ft (9 metres) long. This was by design to help it eat from the highest parts of the trees, where many other plant eating dinosaurs couldn’t reach.

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.
