摘要	A new clutch of a rarely described oospecies, Nanhsiungoolithus chuetienensis is detailed in this work. The clutch contains 14 eggs radially arranged in two concentric rings, representing the most complete clutch of N. chuetienensis yet described. The morphology and microstructure of this new specimen align with those of the previously studied N. chuetienensis specimens. Notably, the eggshell displays reticulatituberculate ornamentation, introducing a new characteristic for this oospecies. The specimen also reveals microstructural variation along the egg body, including thickness, mammillae shape, and EBSD characteristics. Combining prismatic morphotype, reticulatituberculate ornamentation, and broad mammillae, this study amended the diagnosis of Nanhsiungoolithus. Importantly, Montanoolithus, Reticuloolithus, and Paraelongatoolithus, which were presumed to be putative dromaeosaurid eggs, share this combination and are therefore considered junior synonyms of Nanhsiungoolithus. As a result, the oogenus Nanhsiungoolithus now belongs to the oofamily Montanoolithidae. The similarity of the clutch structure between montanoolithid and elongatoolithid eggs indicates that dromaeosaurids may share a similar clutch structure to that of oviraptorids.
