结节龙属(属名:Nodosaurus)是种草食性恐龙,属于鸟臀目,生存于晚白垩纪,化石发现于北美洲。目前已在怀俄明州堪萨斯州发现两个不完整标本,没有头颅骨。结节龙是北美洲所发现最早的装甲恐龙之一,由奥塞内尔·查利斯·马什(Othniel Charles Marsh)在1889年所命名。

结节龙科恐龙身长约4到6.1米。身体上侧覆盖者皮状骨板,身体两侧各有一排尖刺。背部的皮状骨板以一层薄、一层宽的环状方式排列。较宽的皮状骨板上有骨质瘤[1]

牠们拥有短四肢、脚掌上有五个脚趾、短颈部,以及长而僵硬、缺乏骨槌的尾巴。头部狭窄,有尖状口鼻部、强壮的颌部、以及小型牙齿[1]。结节龙可能以软植物为食,因为牠们似乎不能咀嚼坚硬、多纤维的植物;或可能吞食胃石以磨碎坚硬植物,或拥有巨大的肠胃器官以消化坚硬植物。

结节龙被认为没有尾巴的骨槌,牠们没有多少结构可用来防卫。当受到威胁时,结节龙可能趴在地上,这样只曝露充满装甲的背部与两侧,如同今日的刺猬

北美洲东部发现了不同的结节龙鳞甲,因此科学家有机会可以辨别结节龙属的鳞甲。
