Brachiosaurus means "arm lizard" because this reptile (not lizard!) had longer front legs than back legs. But when readers see the spectacular images featured in this book, they'll be much more impressed by the dinosaur's very, very long neck. They'll also learn about scientists' evolving understanding of how Brachiosaurus lived, including what this plant eater ate and how much (hint: a lot!). Significant science concepts are presented using at-level vocabulary and visual elements throughout the text, such as maps and labeled pictures, which are especially helpful to visual learners.
