Abstract
Students will analyze the coevolution of the predator–prey relationships between Tyrannosaurus rex and its prey species using analyses of animal speeds from fossilized trackways, prey-animal armaments, adaptive behaviors, bite marks on prey-animal fossils, predator–prey ratios, and scavenger competition. The students will be asked to decide whether T. rex was a predator, an opportunistic scavenger, or an obligate scavenger.
