Title of Lecture: What dinosaur tracks and traces tell us about how they lived

Lecture Description: Dinosaur bones can provide us will all kinds of information about what these extinct animals looked like, but often we cannot say much about their behaviors. Andrew will discuss how dinosaur tracks can provide lots of information about behaviors such as walking, running, limping, swimming, sitting, hopping, turning, moving in herds or flocks, and even burrowing. In rare circumstances when tracks are exceptionally preserved, they can provide us with information about the what the feet and/or hands looked like by their shapes, arrangement of toe pads, and sometimes by the preservation of scales, skin, and/or wrinkles. In rare conditions, other parts of the body may also leave traces, such as the tail, belly, or even ischial callosity, a fancy name for a “butt” trace.
