摘    要:本文描述了贵州遵义下寒武统牛蹄塘组生物群和台江中寒武世凯里生物群中保存完整的斗篷海绵科(Choiidae)中斗篷海绵(Choia)和小斗篷海绵(Choiaella)化石标本,共计2属2种2未定种:Choia zunyiensis sp.nov.,Choia sp.,Choiaella avata sp.nov.和Choiaella sp.。Choia分布很广.在我国下寒武统澄江生物群及北美中寒武统的四大生物群中均有产出。Choiaella原仅产于我国澄江生物群,凯里生物群中Choiaella的发现使其时代上延至中寒武世。贵州早、中寒武世斗篷海绵科的发现及研究为海绵动物的早期演化及古地理学等方面的研究提供了重要的新材料。

关 键 词:海绵动物  牛蹄塘组生物群  凯里生物群  寒武世  贵州  化石标本

Abstract:Here described are well preserved Choiidae (sponges) including two genera, two new species and two sp. indet.: Choia zunyiensis sp. nov. and Choia sp. from the Lower Cambrian Niutitang Formation Biota at Songlin town of the Zunyi area; Choiaella ovata sp. nov. and Choiaella sp. from the Middle Cambrian Kaili Biota at Balang village, Taijiang County, Guizhou. Choia was originally described from the Lower Cambrian Chengjiang Biota, Yunnan, S W China and the Middle Cambrian biotas in North America. Choiaella was originally found in the Lower Cambrian Chengjiang Biota. The discovery of Choiidae from the Early and Middle Cambrian in Guizhou provides new information on early metazoans.
Keywords:Spongia Niutitang Formation Biota Kaili Biota Early and Middle Cambrian Guizhou
