Abstract

The genus Chasmazoon is introduced for Cellepora abdita MacGillivray (1895) from the Tertiary of Victoria. Chasmazoon abditum has colonies capable of both an encrusting and free-living mode of growth, and the latter were probably anchored by basal rhizoids. The large, simple orifices and striated, peristomial ovicells of C. abditum are distinctive, and Stichoporina parvicapitata Canu & Bassler (1935), which has closely similar characters, is considered to be synonymous.

隶属于维多利亚第三纪abdita Cellepora MacGillivray的一新属Chasmazoon gen. nov.

从维多利亚第三纪为Cellepora abdita MacGillivray(1895)引入了Chasmazoon属。abditum Chasmazoon的菌落既具有包壳生长模式，也具有自由生长模式，后者可能是由基生根状体锚定的。abditum的大而简单的孔口和有条纹的卵周细胞是独特的，与具有非常相似特征的Stichoporina parvicapitata Canu & Bassler(1935)被认为是同义词。
