A Secret History of Life on Land

A Secret History of Life on Land

This story from Discover Magazine follows the career of paleontologist Stephen Hasiotis, who specializes in terrestrial ichnology, as he searches for the tracks of ancient invertebrates, even where a fossil record is lacking. This paper covers his studies of the ancient termite mounds of Gallup, New Mexico; his early work on crayfish burrows of Utah; his work in the Petrified Forest National Park in Arizona, including his discovery of a bees' nest in a forest area which is older than the rise of flowering plants; and his discovery of dermestid beetle markings on dinosaur fossils at the Dinosaur National Monument on the Utah-Colorado border.
