Dino Trace Fossils Part 2: Bite Marks, burrows, scars, and more

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
