Aptian–lower Cenomanian sedimentary rocks, assigned to the Risan Aneiza and Halal formations and exposed in northern Sinai yield rich, well-preserved echinoid assemblages. Thirty-two species (16 regular and 16 irregular), in 27 genera, have been identified and are here systematically described from the Gebel El Tourkumanyia and Wadi El Karm sections (El Maghara area). A new genus, Sinaiosalenia, and two new species, Sinaiosalenia rhombohedralis (lower Cenomanian) and Globator aegyptiaca (middle Albian), both from Gebel El Tourkumanyia, are erected. Additionally, two species are recorded from Egypt for the first time: Emiratia raskhaimahensis Ali, 1990 and Pseudananchys ludovici (Fourtau, 1912).

Aptian-Lower Cenomanian 沉积岩，属于 Risan Aneiza 和 Halal 地层，出露在西奈北部，产出丰富、保存完好的海鞘组合。已从 Gebel El Tourkumanyia 和 Wadi El Karm 部分（El Maghara 地区）确定了 27 属的 32 种（16 种规则和 16 种不规则属），并在此进行了系统描述。一个新属Sinaiosalenia和两个新种Sinaiosalenia rhombohedralis（下 Cenomanian）和Globator aegyptiaca（中阿尔比安），都来自 Gebel El Tourkumanyia，被建立起来。此外，埃及首次记录了两个物种：Emiratia raskhaimahensis Ali，1990 和Pseudananchys ludovici（Fourtau，1912）。
