恐虾纲

史前節肢動物類群

恐虾纲（学名：Dinocaridida）是节肢动物门下的一个基干化石类群，旧时也被归为叶足动物门。此类动物均为海生，于寒武纪时最为繁盛，偶有奥陶纪的记录[3]，还有一类名为申德汉斯虾（Schinderhannes）的成员生活在泥盆纪中早期[4]。恐虾纲的学名“Dinocaridida”源自古希腊文“δεινός”（拉丁转写：deinos；恐怖的，可怕的）＋“καρίς”（caris；螃蟹，虾），意指其某些成员为当时最大的捕食者[1]。

一些文献有时会将恐虾类称作“AOPK 群”[5][6][7][8]，因为它包含四个基本支系，即以奇虾（Anomalocaris）为代表的放射齿目，以及欧巴宾海蝎科、厌恶虫属和宣扬爪虫科。它们的共同特征是有一对前附肢，并且身上有许多叶片。然而，它们极有可能是并系的，研究显示放射齿目、欧巴宾海蝎和其他节肢动物在演化树上聚为一支，而厌恶虫和宣扬爪虫则处在更加基底的位置[5][9][10]。

分类

恐虾纲的分类位置尚不明确，可能为节肢动物干群成员，但有时也被归入叶足动物门[11][12]。其下基本可分为两大类群：奇虾类和欧巴宾海蝎类，据推测这些动物是其所属时代的顶级掠食者[13]。

恐虾纲内部的详细分类如下：

分布

该群分布广泛，在加拿大、美国、格陵兰、中国、澳大利亚和俄罗斯的寒武纪地层以及摩洛哥的奥陶纪和德国的泥盆纪均有发现。
