ABSTRACT

A re-examination of the holotype of the Rhaetian (Late Triassic) clam shrimp Loxomegaglypta luchangensis has revealed that the large-sized reticulations are located in the upper part, and the small-sized reticulations in the lower part of each growth band in the middle part of the carapace. The distal growth bands are ornamented with small-sized reticulations. These features indicate that the species should be assigned to Shipingia. This discovery indicates that Shipingia has ranged to Rhaetian (Upper Triassic).
