Like other books in this series, this book is a taster on the subject, so you may end up needing to read more if you get really interested. But what is here is told pretty well, so it does make a good starter. The author has experience in this field, so some of that is part of the text, but only where it’s fitting, so not too much. There are pictures and such too, so it’s not just text. At the end is some further reading.
The study of dinosaurs begins in mid 1800s, though proper start on the subject as we know it only gets serious one in the 1960s and 1970s when people really start finding interesting stuff (like bird ancestors and medium-sized predators), and technology is sufficient enough to ease finding and researching bones and things that surround them in right places.
We get stuff like dating things and categorising things into eras. The origins of the dinosaurs remains incomplete, and so does many other things, but as technology progresses, it gets a bit easier to find out about things. Certain dinosaurs are used in this book as examples of finding out what they were like in real life, etc.
Some questions answered: why dinosaur bones are rare? Were they cold or warm blooded? Can DNA be used to bring dinosaurs back to life like in ‘Jurassic Park’? What parts of the evolution from dinosaurs to birds have been found?
Studying dinosaurs: what can be found out about them through skeletons, how soft-tissue prints help (skin, brain), how genealogy is used to study dinosaurs’ evolutionary history, what can be found about some parts that no longer exist (circulation and lungs, brains, bones), how the change in going from one continent to several changed the dinosaurs. What kind of research? - Foot prints, the dung, illness/injury in bones, use of isotopes on bones, scanning possibilities (which also help to reveal fakes).
I didn’t know that the dinosaur-destroying meteorite fact was discovered so recently (1980s to around 1991)! It’s interesting, too, to read that the mythical figure of the griffin was based on nomadic travelers finding Protoceratops skeletons and imagining things further.
The author ends the book with a thought on what the humans will leave behind when we eventually will be gone, and hoping we’ll leave things in good enough shape for whoever/whatever comes next. So: a good taster, often interesting, and I think you might want to continue reading with another, deeper book. A good starting point with a light feel.
