This illustration depicts the food web for ecological groups in the late Cretaceous Period as reported in a new paper published in the Proceedings of the National Academy of Sciences. Each ecological group includes a set of species that share the same set of potential predators and prey. Silhouettes show iconic members of each group. Arrows show who eats whom.
