Abstract
Pyramidelloides dolini n. sp., older strongly sculptured eulimid, is described from the Middle Eocene of southwestern Alabama (Gosport Sand). This new species probably had a planktotrophic larval stage similar to the recent Indo-West-Pacific species. Relationship with the species of the genus Palisadia is discussed. Geographic distributions of both the fossil and the recent species of the genera Pyramidelloides and Palisadia support finally a classic pattern in tropical marine biogeography: a discontinuous geographic range between Indo-Pacific and Caribbean provinces.
dolini n. sp.,较古老的强雕刻的真鲷,描述自始新世中阿拉巴马州西南部(戈斯坡沙)。这个新物种可能有一个浮游营养化的幼虫阶段,类似于最近的印度-西太平洋物种。讨论了其与巴利沙迪亚属植物的关系。金字塔属和Palisadia属的化石和新物种的地理分布最终支持了热带海洋生物地理学的经典模式:印度太平洋和加勒比省份之间的不连续的地理范围。
