What did dinosaurs really look like? The best attempts to answer this question are constantly changing. Rubin shows how each major find in paleontology, as well as the techniques and creativity used by paleoartists, have produced improvements in scientifically grounded artistic illustrations. For the iguanodon, unearthed in the early nineteenth century, each subsequent discovery of new fossils, including complete skeletons, was a big help (and one discovery showed that what was thought to be a horn was really a thumb-spike). But equally important were the theoretical advances that led scientists to think of dinosaurs as more akin to modern birds than to modern reptiles. The illustrations for the most recent theories are some of the most exciting, adding colorful flesh, wattles, and feathers reminiscent of the variations in birds. Rubin’s pencil, watercolor, and “digital collages” (from the copyright page: “The artist is not entirely sure what to call all this, but ‘digital collage’ sort of makes sense”) portray the paleontologists and artists of each era alongside a rendition of the time period’s signature dinosaur, with humorous asides from both species. A helpful text box accompanies the dinosaur portraits and includes a list of their key features, facilitating comparisons across the history of paleontology. Endnotes provide additional backstory as well as source illustrations from prominent historical and contemporary paleoartists.
