据美国《美国科学院学报》报道,科学家们已经根据化石牙齿上的划痕和磨损的模式重建了鸭嘴恐龙——埃德蒙顿龙(Edmontosaurus)的饮食习惯——埃德蒙顿龙以矮生植被为食,而不是以木质细枝和树叶为食。埃德蒙顿龙这样的恐龙是白垩纪晚期最大型的脊椎动物之一,它们觅食的成功归功于它们的头骨结构,这种结构让它们能够咀嚼并磨碎食物。不过,尽管脊椎动物牙齿化石可以提供一些饮食的线索,现在仍然不清楚埃德
According to the Proceedings of the National Academy of Sciences, scientists have reconstructed the duckbill dinosaur based on the pattern of scratches and abrasion on fossil teeth - the eating habits of Edmontosaurus - the Edmonton dragon is shorter Vegetation is for food, not for wood twigs and leaves. One of the largest vertebrates of the late Cretaceous, the Edmonton Dragon, a dinosaur, owes its success to foraging to their skull structure, which allows them to chew and grind food. However, although vertebrate fossil teeth can provide some clues to the diet, it is still unclear about Ed
