Spinosaur Tales, David Hone and Mark P. Witton, is as thorough and exhaustive a detailing of what we currently know about this fascinating dinosaur (I realize “fascinating dinosaur” is redundant), as well as what we don’t know, which is vitally important for a creature whose fossil record is woefully scarce. Both writers are scientists (Witton is also a paleoartist and his illustrations are included) and have written both books and scientific papers, but the book is not aimed at scientists or academics. It hits the sweet spot for what I’d call “informed laypeople.” Those who read popular science article or books and so won’t be thrown by references to “clades,” for instance. That said, while we get a brief (very brief) intro into some anatomical terms early on, the book is relatively free of specified terminology, and what is there is always either clear from context or clearly explained by the authors.
Similarly, the structure is logical and easy to follow, and the writing flows extremely well, from sentence to sentence, paragraph to paragraph, and chapter to chapter (13 in all, including a general introduction). The early chapter tend to be broad-based, covering the basic history of research into spinosaurids (including the tragic loss of the original specimen when the museum housing its fossils was bombed in WWII), their placement in the larger grouping of dinosaurs, the various types of spinosaurids, and a brief tour of their fossil record. Then we get several detailed chapters on anatomy, specifically on the head, the “body, limbs, and tail,” and appearance, followed what they anatomy might tell us about their locomotion (particularly their ability to swim well), feeding methodology, reproduction and socialization, and how they might have interacted with the surrounding ecology.
As noted, all of this is laid out wonderfully clearly and also without any hype or sense of undeserved certainty. Thanks to the aforementioned dearth of fossils, there’s a lot of past surmises that have been overturned with newer fossils or better technology. The authors are more than generous in how they portray these errors, showing how while prior scientists were wrong in various interpretations, those analyses made sense based on what they were working with. Similarly, they are even-handed in their presentation of various theories, giving views they don’t necessarily agree with themselves a fair airing, pointing multiple times to how the poor fossil record means much is going to be pure conjecture and thus being willing to say their views could be wrong (though they do a convincing job of making clear why they think that’s not highly likely). As for instance when they provide a host of separate anatomic reasons why theories that Spinosaurus was an adept swimmer will probably not be confirmed, such as the drag caused by that large sail on their back, the lack of streamlining in their legs, their bone density, and others. You can see how it might turn out to be the case — as noted, the writers are fair to the other side — but you leave pretty sure it won’t.
Beyond the clarity and thoroughness of the text, the book contains a number of helpful diagrams and illustrations and also, at the end, a good number of plates showing the spinosaurids in action, such as one of a Baryonyx fishing or another of two Suchomimus rivals wrestling with each other.
Spinosaur Tales is a great example of a focused popular science book. Because of its narrow focus on a single group, one gets the sense by the end that one knows all there is about the creatures (with the caveat provided by the authors that more is coming to light all the time). And while in lesser hands, such thoroughness might have led to an overly dense book, or one that lost the reader at times in a thicket of information or confusing terminology, structurally and stylistically, the authors have nailed it so that it all reads smoothly and clearly. Highly recommended.
