''Occacaris oviformis'' was a nektonic predatory arthropod from the Lower Cambrian Maotianshan shale Lagerstätte. It bears a superficial resemblance to the Cambrian arthropod, ''Canadaspis'', though, was much smaller, and had a pair of "great appendages," with which it may have grasped prey. It had a bivalved carapace that covered most of its body, leaving only the last two tergites of its trunk, with the telson jutting out of the posterior end of the carapace, and the eyes, antennae, and great appendages jutting out of the anterior end. The spines of the great appendages are paired, setting it apart from its relatives, ''Fortiforceps foliosa'', and ''Forfexicaris valida''. ==See also== * Arthropod * Cambrian explosion * Chengjiang biota * * List of Chengjiang Biota species by phylum 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Occacaris」の詳細全文を読む スポンサード リンク
