扁角龙属(属名:Platyceratops)是种角龙亚目恐龙,生存于晚白垩纪坎潘阶,约7500万年前到7200万年前。扁角龙的化石发现于蒙古。牠们的头颅骨大于弱角龙;牠们曾被归类于弱角龙科新角龙类模式种鞑靼扁角龙Platyceratops tatarinovi),是由Aliafanov在2003年所叙述。属名在古希腊文意为“平坦的有角面孔”。

分类

[编辑]

扁角龙属于角龙亚目,角龙亚目恐龙是群植食性恐龙,拥有类似鹦鹉的喙状嘴,生存于白垩纪北美洲亚洲。所有的角龙类恐龙在白垩纪末期灭绝。

扁角龙可能是弱角龙的变异个体[1]

食性

[编辑]

如同所有角龙类恐龙,扁角龙是植食性动物。在白垩纪期间,开花植物的地理范围有限,所以扁角龙可能以当时的优势植物为食,例如:蕨类苏铁针叶树。牠们可能使用锐利的喙状嘴咬下树叶或针叶。
