What does ankylosaur eat?

Ankylosaurus was an herbivore, or plant eater. Their heads were very low to the ground, only about three to four feet high, and thus they probably ate low growing plants. Their teeth were designed for cutting vegetation, and they couldn't chew, so they probably ate relatively tender plants that were easy to digest. Plants that existed at the same time and place as Ankylosaurus include ferns, horsetails, early flowering plants, conifers, cycads, palm trees, and ginkgoes, but they probably couldn't reach the leaves of the latter four.
