人们对来自海洋钻探地点的古新世介形类的分类知之甚少。在此，我们报告了来自西北大西洋纽芬兰岛综合海洋钻探计划第 342 号远征 U1407 的白垩纪-古新世沉积物中的 Eucytheridae、Krithidae、Thaerocytheridae、Trachyleberididae 和 Xestoleberididae 科的 14 种介形类物种。我们描述了科学上新发现的五种 trachyleberidid 物种：Croninocythereis clavae sp。十一月，Phacorhabdotus flabellicarinus sp。十一月，Poseidonamicus Norrisi sp。十一月，Ryugucivis blumi sp。 11 月，和 Trachyleberidea cronini sp。十一月
Abstract.
Little is known about the taxonomy of Paleocene ostracodes from ocean drilling sites. Herein, we report 14 ostracode species of the families Eucytheridae, Krithidae, Thaerocytheridae, Trachyleberididae, and Xestoleberididae from Cretaceous-Paleocene sediments at U1407 of Integrated Ocean Drilling Program Expedition 342 off Newfoundland, Northwestern Atlantic. We describe five trachyleberidid species new to science: Croninocythereis clavae sp. nov., Phacorhabdotus flabellicarinus sp. nov., Poseidonamicus norrisi sp. nov., Ryugucivis blumi sp. nov., and Trachyleberidea cronini sp. nov.
