Rather than a standard (if short) audiobook, this audiobook contains many snippets of interviews with scientists. So in a sense, it resembles a radio show or a podcast.
It's structured very well. I wasn't sure what to expect, and hoped for more than a list of dinosaur facts (a la a children's book). And my expectations were met and exceeded: not only does the book provide an overview of the entire timeline of the dinosaur's existence on earth, it also provides a lot of context, and often even outlines specific scientific methods that were used to get to this or that conclusion. That's very appreciated - many pop-sci books just quote facts that "scientists discovered", without even mentioning how, which feels a little incomplete.
