| 摘 要： | 河源盆地沉积了白垩系-古近系，笔者将这套地层划分为3个岩石地层单位，新建仙塘组和东源组，沿用格岭组。在河源除发现恐龙骨骼、恐龙脚印、龟鳖化石外，于白垩系东源组中还产有大量蛋化石。该组蛋化石的分布，下部以圆形蛋为主，中-上部多见长形蛋。报道了三王坝村副圆形蛋(新种)Paraspheroolithus sanwangbacunensis Fang sp．nov．、风光村树枝蛋(新种)Dendroolithus fengguangcunensis Fang sp．nov．和瑶屯巨形蛋Macroolithus yaotunensis、长形长形蛋Elongatoolithus elongates。 |

| Abstract: | The Heyuan basin is located in east-central Guangdong Province, where the Cretaceous-Neogene strata are widely distributed. This sequence of strata is divided into three formations, namely, the Geling Formation and the newly-erected Xiantang and Dongyuan formations. Apart from dinosaur bones, dinosaur footprints and fossil turtles, large numbers of fossil eggs are also found in the Cretaceous Dongyuan Formation of this basin. In the lower part of this formation Spheroolithus-type eggs are dominant, while in the middle and upper parts mainly Elongatoolithus-type eggs are found. This paper describes Paraspheroolithus sanwangbacunensis sp. nov., Dendroolithus fengguangcunensis sp. nov., Macroolithus yaotunensis and Elongatoolithus elongates. |
