Environment and Habitat
During this time sea level was high and the oceans were warm. In general the global climate was warmer than today with no polar ice caps present. Most of the land was covered by tropical vegetation such as gymnosperms, and conifers. The ankylosaurs were not tall animals compared to other dinosaurs. Therefore, they would have eaten only low lying vegetation and likely not leaves from trees. Some of the ankylosaurs stomach contents have been found, but their exact diet is still unknown.

These three types of vegetation were very common in the Cretaceous and likely contributed to a large part of the ankylosaurs diet. Ferns, horsetails and mosses also likely contributed to a fair portion of the ankyosaurs diet.
