File:Nanxiong Formation egg clutches.png

English: The oviraptorid clutches described in this study. All clutches were discovered from the Late Cretaceous Nanxiong Formation at a construction site in Dayu County, Ganzhou City, Jiangxi Province, China (25.386N, 114.369E) and now are reposited at various institutions (Table 2). All eggs are arranged in pairs with their blunt ends pointing towards the clutch center devoid of eggs. A. Top view of HGM-41H-V0074, a complete clutch with 30 eggs arranged in three superimposed rings. Two isolated eggs in the upper right might have been pushed away from the uppermost ring before burial. The vacant center is 266 × 213 mm. B. Top view of DM-2014-P0154, a complete clutch with 31 eggs arranged in four superimposed rings. The vacant center is comparatively smaller than in the other specimens studied, measuring only 133 ×105 mm. C. PFMM-0014002972; C1, top view of the specimen with 32 eggs arranged in three superimposed rings, the vacant center is 240 × 135 mm; C2, detail of the lateral view from the center of the specimen; three rings of eggs are separated by thin layers of sediments; yellow dashed line, the major axis (46 mm); red dashed line, the minor axis (24 mm); scale bar 50 mm. D. Top view of PFMM-0014004392, a complete clutch with 32 eggs arranged in three superimposed rings. The vacant center is 200 × 186 mm. E. Bottom view of PFMM-0014003019, a complete clutch with 35 eggs arranged in three superimposed rings. The vacant center is 293 × 280 mm, which is the largest opening among the specimens described in this study. Arrows point to the opening in the lowermost ring.
