Big Babies

For dinosaur lovers and fans of Steve Jenkins's Prehistoric Actual Size, this unexpected look at prehistoric life explores what is known about our favorite extinct creatures before they became massive, full-grown adults.

How big (or small) was your favorite dinosaur–as a baby? We see how some stack up, alongside childhood favorites such as a toy truck or a rubber duck. Did you know that T. rex hatchlings were only about the size of a turkey? Or that the huge, long-necked brontosaurus are said to be only eleven pounds at birth? 

In this early picture book, young readers learn that before dinos grew to be large and powerful, they started off as something much smaller to behold.
