Wang, Yaqiong, 2025, First report of the non-marine ostracod fauna from the Lower Cretaceous Xiaonangou Formation of the Baishan Basin, NE China, Zootaxa 5660 (4), pp. 560-572 : 562

Genus Cypridea Bosquet, 1852

Type species. Cypris granulosa ( Sowerby, 1836)

Cypridea sp.

Figs. 2 , 3A–B .

Material. One deformed carapace.

Remarks. Although only a deformed carapace was found, this specimen matches the morphologic characteristics of the genus Cypridea , having a rostrum. Due to the poor preservation of the specimen, it cannot be identified to the species level.
