Punctatestheria clam shrimp Yaojie Formation Jurassic China

Abstract

A new spinicaudatan species Punctatestheria yaojieensis Xue & Li sp. nov. is described from the Middle–Upper Jurassic Yaojie Formation at Yaojie in Lanzhou City, Gansu Province, China. In addition to the only evenly distributed sparse puncta, the special ornamentation of Punctatestheria, the new species has setal remains on the growth lines in the ventral or middle part of the carapace, and puncta are arranged in a linear manner in the postero-ventral part of the carapace.
