英國古生物學家8月27日發表的最新研究顯示，1億6500萬年前、最早的甲龍類恐龍之一，生活在侏羅紀中期的「刺圈龍」（Spicomellus），身上有著非常厚重的盔甲，全身長滿尖刺，有的甚至長達87公分，讓人聯想到超級瑪利歐中知名的反派角色「庫巴」。

刺圈龍含有六根肋骨尖刺、帶有兩對尖刺的「項圈」，而尾巴可能有某種「武器」，可能也是尖刺，用於防禦與展示。英國自然史博館（Natural History Museum）古生物學家麥達曼特（Susannah Maidment）說，在動物身上如果發現奇怪的大型結構，沒有明顯的功能性，往往與求偶有關，刺圈龍帶有尖刺的項圈可能即屬此類。

後期甲龍則演化出較簡單的盔甲，功能更趨近於保護而非展示。這篇刊登在《自然》（Nature）研究，同時也將恐龍「尾部武器」的起源往前推進了3000萬年。窗框矽利康
