How a paleontologist got his career on track

Ichnology is a subdiscipline of paleontology that focuses on tracks and traces. "This way of seeing prehistoric life has no greater champion than Emory University paleontologist Anthony Martin," writes Brian Switek on the National Geographic site Phenomena. "Martin has pondered over the meaning of dinosaur burrows, cataloged how traces of modern life can help us interpret the past, and eloquently expressed why no picture of the past is complete without considering what trace fossils tell us."

Watch the above video to learn more about Martin's philosophy on developing "ichnovision."
