Image: Ichnology is the study of trace fossils of once-living things. Burrows, trackways, trails and borings are all examples of traces made by organisms. Scientists study traces made by plants and animals to try to determine their behavior. A species name given to a fossil is called an ichnospecies.
Here: Asteriacites (sea star trace fossil) from the Devonian of northeastern Ohio. It appears at first to be an external mold of the body, but the sediment piled between the rays shows that it is a burrow. Photograph taken by Mark A.

Dinosaurs Without Bones: Dinosaur Lives Revealed by their Trace Fossils, by Anthony J. Martin (Author). 1st Edition.
CSI meets Jurassic Park in a fascinating, revelatory look at dinosaurs and their world through the million-year-old clues they left behind
What if we woke up one morning and all of the dinosaur bones in the world were gone? How would we know these iconic animals had a 165-million-year history on Earth, and had adapted to all land-based environments from pole to pole? What clues would be left not only to discern their presence, but also to learn about their sex lives, raising of young, social lives, combat, and who ate who? What would it take for us to know how fast dinosaurs moved, if they lived underground, climbed trees, or went for a swim?
Welcome to the world of ichnology, the study of traces and trace fossils―such as tracks, trails, burrows, nests, tooth marks, and other vestiges of behavior―and how, through these remarkable clues, we can explore and intuit the rich and complicated lives of dinosaurs. With a unique, detective-like approach, interpreting the forensic clues of these long-extinct animals that leave a much richer legacy than bones, Martin brings the wild world of the Mesozoic to life for the Twenty-first century reader. 24 pages of color and B&W illustrations
