Description: This book is part of the 'Little Doctor's Amazing Discoveries' series, which brings children's curiosities to life in three-dimensional form. Compared to typical books that come in large formats to match their subject matter, this book is relatively small (19.8cm x 19.6cm), but when you open it up, an amazing world is hidden inside. As children turn, flip, and unfold the pages in various ways, their questions are answered one by one. For example, unfolding a hidden flap reveals the process of a dinosaur becoming a fossil. In this way, the book shows children—who can otherwise only imagine such things—various aspects of dinosaurs from many different angles: What did the Earth look like when dinosaurs lived? How varied were their appearances? Why did dinosaurs go extinct? What weapons did dinosaurs have? Perhaps it is precisely because we can never see a real dinosaur that children are able to spread the wings of their imagination. Unlike typical science books that simply hand children one-way knowledge, this book guides children to discover knowledge on their own through play and enjoyment. Furthermore, breaking away from the standard book format, its folded, cut, and inserted pages give children a sense of imaginative fun that adds to the joy of reading.

The largest dinosaurs measured 30 meters in body length and stood 15 meters tall. Their bodies were as large as a five-story building, and they weighed as much as twenty elephants combined. Compsognathus, on the other hand, weighed only 4 kilograms—about the size of a hen. Dinosaurs' bodies were covered in scales. Could their bodies have had various colors like gray, green, and red? Or perhaps spots or stripes? No one knows for sure. The name 'dinosaur' was given by British scholar Richard Owen in 1842, meaning 'terrible lizard.' In fact, while dinosaurs resemble lizards in some ways, they are actually very different animals. Some dinosaurs walked on all four legs, while others walked on two hind legs. Among them were some very fast runners. Struthiomimus, a dinosaur about the size of an ostrich, could run at speeds of up to 50 kilometers per hour. --- Excerpt from the text
