We're back in the Jurassic! Tall, tall trees everywhere — and the forest smells green and warm. But wait. The very TOPS of the trees are shaking. Leaves come raining down from somewhere WAY up high. What could possibly reach all the way up there?

Look UP… waaaay up… it's a BRACHIOSAURUS! Say it with me — BRAK-ee-oh-SOR-us! She's one of the tallest dinosaurs that ever lived, as tall as a FOUR-STORY BUILDING. Her long, long, LONG neck reaches right up into the treetops.

And look at her legs — the front ones are LONGER than the back! Most dinosaurs are the opposite. That's why her shoulders sit so high and her back slopes down. Her name means arm lizard. And that neck? Longer than a giraffe is TALL!

She's looking around from way up high! Where is she headed?

How Tall Was Brachiosaurus?

Brachiosaurus stood about 40 feet (12 meters) tall, roughly as tall as a four-story building. Its secret was its legs: unusually for a dinosaur, its front legs were longer than its back legs, so its shoulders sat high and its long neck rose up from there. That's where its name comes from, too: Brachiosaurus means "arm lizard." Its neck alone was longer than a giraffe is tall.

What Happens in the Story

In Brachiosaurus' Treetop View, your child follows a Brachiosaurus through the Late Jurassic, about 150 million years ago, and chooses where she goes next. Four paths lead to four different endings:

  • Watch a young Brachiosaurus stretch for leaves it can't reach, and see how a grown-up helps

  • Spot a "tiny" creature far below that turns out to be a Stegosaurus

  • Find a grove of ginkgo trees, a kind of tree that still grows today

  • Join a whole group of long-necks at the water's edge

More Brachiosaurus Facts

  • Brachiosaurus lived in what is now North America.

  • It weighed about as much as twenty cars.

  • It ate thousands of leaves a day without chewing: its spoon-shaped teeth stripped leaves off branches, and it swallowed them whole.

  • Its bones were full of air pockets, like a bird's, which helped keep that giant body lighter.

Frequently Asked Questions

What did Brachiosaurus eat?

Plants, and lots of them. It browsed leaves from the tops of tall trees like conifers and ginkgos, eating for most of the day.

Was Brachiosaurus the biggest dinosaur?

It was one of the tallest, but not the heaviest. Some other long-necked dinosaurs, like Argentinosaurus, weighed much more.
