胎壳,protoconchs
1)protoconchs胎壳
1.Further research on gastropod fossils of the Early Cambrian,China shows that early gastropod Archaeospiriids,Auriculaspiriids and Xinjispiriids are all characterized by openly coiled initial whorls(protoconch),but their protoconchs are distinguished by typical marks from the successive whorls.对中国早寒武世软体动物腹足类标本的再研究表明,早期腹足类Archaeospiriids,Auriculaspiriids和Xin-jispiriids无一例外都以开放松旋型初始壳(胎壳)为特征,但这些腹足类的胎壳与后续螺壳的分界各具标志。
