Every stage in a dinosaur's life left behind trace fossils: claw marks from a parent excavating a burrow, eggshells left by hatchlings, fossilized digested food, battle scars, and ultimately, tooth marks left by predators or scavengers.

Dinosaur of the day Bihariosaurus, a small iguanodontian that lived in the Early Cretaceous in what is now Romania.

Some of the ichnology topics we cover this week:

• Dinosaur bones with punctures, grooves, and scrapes help to identify their predators (or scavengers)
• Eggs show evidence of communal nesting and the mother's body temperature
• A filled-in burrow preserved the dinosaur that was sleeping inside
• Fossilized regurgitate, gut contents, and feces all tell us about what dinosaurs ate
