摘要
通过对获自瓮安生物群与宽川铺生物群中大量球形类化石的系统研究,建立了便于交流和深入讨论的球形类化石形态分类方案,对各种类型的球形类化石进行了属性探讨,并按形态属描述球形类化石4个新类型(相当于形态属),8个新种类(相当于形态种)。研究表明球形类化石是一个多源的非正式生物类群,包括动物性和植物性球形类化石,具有丰富的研究内涵,对揭示早期生物的起源、演化、多样性及胚胎发育具有深远意义。
By systematically studying on spheroidal fossils gathered from Weng’an Biota and Kuanchuanpu Biota, the authors put forward a table of form classification for spheroidal fossils for everybody easy to communicate and discuss and inquire into animal or plant attribute of spheroidal fossils. According to the form genus, 4 new types ( equal to the form genus) and 8 new kinds (equal to the form species) of the spheroidal fossils are described.The sperioidal fossil is an informal biota from various sources.It includes sperioidal fossils of animal and plant.Study on these fossils has very abundant content,and has far-reaching significance for revealing the orgin, evolu-tion,diversity and development of embryos of metazoans.
