【Abstract in Chinese】 自从Triglypta Wang(1984)属建立以来,在国内、外陆续发现了一个具有针孔状-小网状-线脊状三种装饰的叶肢介化石群。这个化石群的属种装饰揭示它们之间存在亲缘关系,为此建立三饰叶肢介科Triglyptidae fam.nov.。该化石新科在研究叶肢介的系统演化和地层划分对比等方面都具有重要的意义。

【Abstract】 Since the Triglypta Wang,1984 erected,a new fossil group of clam shrimps with ornamentations of three kinds that are minute punctae-small reticulations-radial striae,has been found one after another in North China and abroad.The ornamentations of the fossil group show a close affinity within them,consequently the Triglyptidae has been erected newly.The Triglyptidae fossils are of important significances for evolution of clam shrimps,stratigraphic subdivision,and mineral exploration.
