The research team, led by paleontologists from the University of Alberta, analyzed the stomach contents of a 75-million-year-old ankylosaur that was found in the Alberta badlands. The ankylosaur, which was named Borealopelta markmitchelli, was a herbivore that weighed about two tons and had a body length of about 20 feet.
The scientists used a variety of techniques to analyze the stomach contents, including microscopy, chemical analysis, and X-ray imaging. They found that the ankylosaur had eaten a variety of plants, including ferns, twigs, and leaves. The ferns and twigs were the most abundant items in the stomach, suggesting that they were the main components of the ankylosaur's diet.
The scientists also found that the ankylosaur had eaten some small stones, which are known as gastroliths. Gastroliths are thought to help animals digest plant matter by grinding it up in the stomach. The presence of gastroliths in the ankylosaur's stomach suggests that it may have used these stones to aid in digestion.
The findings of this study provide new insights into the diet and behavior of armored dinosaurs. The researchers suggest that armored dinosaurs were generalist herbivores that ate a variety of plants, including ferns, twigs, and leaves. They also suggest that armored dinosaurs may have used gastroliths to aid in digestion.
This study is the first to provide direct evidence of the diet and behavior of armored dinosaurs. The findings provide valuable insights into the biology and ecology of these ancient creatures.
