FOSSIL BY FOSSIL

A comparison of select human and dinosaur bones connects readers with some of our more ancient predecessors.

Continuing the approach of Bone by Bone (2013) and Tooth by Tooth (2016), Levine points up parallels between fossilized skulls, ribs, toes, and other skeletal features and those of modern readers as well as prehistoric frills, horns, and the like that we don’t happen to sport. Some of this she presents as easy posers: what sort of dino would you be if you both had a long neck and “your vertebrae didn’t stop at your rear end but kept going and going and going?” Diplodocus, perhaps, or, she properly notes on the ensuing double gatefold, another type of sauropod. What if you had two finger bones per hand rather than five? T. Rex! If your pinky bone grew tremendously long? A pterosaur! Just for fun, in the simple but anatomically careful illustrations, Spookytooth temporarily alters members of a cast of, mostly, brown-skinned young museumgoers (two wearing hijabs) to reflect the exaggerated lengths, sizes, or other adaptations certain bones underwent in dinosaurs and several other types of extinct reptiles. Generous lists of websites and other information sources follow a revelation (that won’t come as a surprise to confirmed dino fans) that birds are dinosaurs too.

Another “humerus” study in comparative anatomy.
