摘要:

描述了发现于中国广东省佛山市南海区大沥镇北村水闸施工工地的三水组红层中的首个始丰石笋蛋(Stalicoolithus shifengensis)蛋窝。这一不完整蛋窝保存有3个近完整蛋化石和两个印痕。基于以下宏观形态和蛋壳显微特征,这些蛋可以被归为石笋蛋类的始丰石笋蛋:恐龙蛋呈球形,平均直径为10.5 cm; 蛋壳较厚,平均厚度为3.50 mm, 由柱状消光的壳单元组成,锥体层与柱状层界线不明显;锥体层的厚度为0.25 mm, 约占蛋壳厚度的1/14, 锥体在弦切面下呈花瓣状;柱状层可分为内层、中间层和外层,其中中间层和外层发育大量次生壳单元,气孔道呈蠕虫状。三水组中始丰石笋蛋的发现补充了这一蛋种的蛋窝信息:恐龙蛋在蛋窝中互相叠加,且相互之间间隔一定的距离。同时,这一发现还拓展了这一蛋种的古地理分布,为讨论三水盆地恐龙蛋的多样性奠定了基础。

Abstract:

The first clutch of Stalicoolithus shifengensis is described here. This incomplete dinosaur egg clutch in which three nearly complete eggs and two egg prints were preserved was discovered in the red deposits of the Sanshui Formation at a construction site near the sluice of North Village, Dali Town, Nanhai District, Foshan City, Guangdong Province, China. The eggs in the clutch are stacked with various ranges. Based on the characteristics of the eggshell, these eggs can be assigned to S. shifengensis. The discovery of S. shifengensis in the Sanshui Formation complements the clutch information about the oospecies as well as expands its paleogeographic distribution, and sets the foundation for discussing the diversity of dinosaur eggs in the Sanshui Basin.

Key words: Sanshui Basin, Guangdong, Late Cretaceous, dinosaur egg, Stalicoolithidae
