Mayor, a folklorist and historian of science, continues the project of understanding what premodern peoples made of fossils that she started in The First Fossil Hunters: Paleontology in Greek and Roman Times
. Surveying accounts of Native American tradition from the earliest Spanish conquistador and missionary records of Aztec and Inca lore up through present-day Indian oral histories, she correlates Native American myths with the fossils they are known or presumed to have observed. The results are unsurprising: giant fossil mastodon and dinosaur bones engendered myths about giants—giant elk, bear, birds, centipedes, subhumanoids and mysterious "water monsters"—who populated the earth until, in a nearly universal motif, they were killed off with lightning strikes by sky spirits. Indian notions of "deep time," changing landforms and climates, and the descent of contemporary species from fossilized ancestors anticipate the insights of present-day geology and evolutionary theory, she contends, while Inca legends of extinction by "fire from heaven" prefigure modern theories of extinction by asteroid impact. Her research makes for a competent if dry study in comparative folklore, but her claim that these myths "evince the stirrings of scientific inquiry in pre-Darwinian cultures" downplays the elements of animism and supernaturalism that are so radically at odds with the materialist and mechanistic thrust of modern science.
