Abstract The irregular echinoid Pygurus meslei Gauthier, 1896 is briefly described from the top part of the Antalo Limestone Formation exposed at Mugher (Blue Nile Basin, Ethiopia). The age of the urchin is constrained by calcareous nannofossils as Upper Tithonian. This is not only the first record of Pygurus meslei Gauthier, 1896 from Ethiopia but also the youngest, worldwide. Very briefly, the African records of Genus Pygurus are also enumerated, and a note on the paleobiogeographic distribution of the genus from the Jurassic deposits of Africa is also provided.

来自 Antalo 石灰岩地层（埃塞俄比亚青尼罗河流域）的 Pygurus meslei Gauthier 的第一个晚侏罗纪海棘突记录

摘要 从 Mugher（埃塞俄比亚青尼罗河盆地）出露的 Antalo 石灰岩组顶部简要描述了不规则海棘鱼 Pygurus meslei Gauthier，1896 年。海胆的年龄受到上提通阶的钙质纳米化石的限制。这不仅是 1896 年来自埃塞俄比亚的 Pygurus meslei Gauthier 的第一个记录，也是世界上最年轻的记录。非常简要地，还列举了 Pygurus 属的非洲记录，并提供了关于非洲侏罗纪矿床中该属的古生物地理分布的说明。
