三叶虫三叶虫Trilobita节肢动物门中已绝灭的一纲。虫体的外壳纵分为一个中轴和两个侧叶，故名三叶虫，由前至后又横分为头、胸、尾3部。三叶虫全属海生，多数营游移底栖生活，少数钻入泥沙中或漂游生活。寒武纪早期出现，种属和数量都很多，到了晚寒武世发展到高峰，奥陶纪仍然很繁盛，进入志留纪后开始衰退，至二叠纪末则完全绝灭。从背部看去三叶虫为卵形或椭圆形，成虫的长为3～10厘米，宽为1～3厘米。小型的6毫米以下。三叶虫体外包有一层外壳，坚硬的外壳为背壳及其向腹面延伸的腹部边缘。腹面的节肢为几丁质，其他部分都被柔软的薄膜所掩盖。一般所采到的三叶虫化石都是背壳。三叶虫背壳的中间部分称为轴部或中轴，左、右两侧称为肋叶或肋部。三叶虫壳面光滑。或有陷孔、瘤包、斑点、放射形线纹、同心圆线纹、短刺等。头部多数被两条背沟纵分为三叶，中间隆起的部分为头鞍及颈环，两侧为颊部，眼位于颊部。颊部为面线所穿过，两面线之间的内侧部分统称为头盖，两侧部分称为活动颊或自由颊。胸部由若干胸节组成，形状不一，成虫2～40节。中间部分为中轴，两侧称为肋部。每个肋节上具肋沟，两肋节间为间肋沟。尾部是由若干体节互相融合而形成的，1～30节以上不等。形状一般半圆形，但变化很大，可分为一中轴和两肋部。肋部分节，有肋沟和间肋沟。肋部可具边缘，边缘上亦常有边缘刺。三叶虫腹面的节肢极少保存为化石，迄今为止全世界已发现节肢化石的只有19个种。三叶虫卵生，经过脱壳生长，在个体发育过程中，形态变化很大。一般划分为3期：幼虫、中年期、成年期。是分类的重要根据之一。三叶虫纲可以分为7目：球接子目、莱得利基虫目、耸棒头虫目、褶颊虫目、镜眼虫目、裂肋虫目及齿肋虫目。中国三叶虫化石是早古生代的重要化石之一，是划分和对比寒武纪地层的重要依据。
