浙江天台盆地晚白垩世恐龙蛋新类型

摘要

In the past ten years,a number of dinosaur eggs were found from the Tiantai Basin in Zhejiang Province,and some oospecies were reported by Fang et al.(2000,2003 ),Jin et al.(2007)and Qian et al.(2008).In 2010,we described and revised 12 oogenera and 15 oospecies belonging to seven oofamilies in this basin (Wang,2010),and some new types were reported (Wang et al.,2010a,b; Zhang,2010).At the same time,we comprehensively surveyed localities and horizons of the dinosaur eggs and compared the dinosaur egg faunas in China ( Wang et al.,in press).Here we report a few more new ootypes of dinosaur eggs from the Tiantai Basin.%浙江天台盆地上白垩统赖家组和赤城山组是我国最重要的恐龙蛋化石产出地层之一.近年来,我们对天台盆地陆相红层中的恐龙蛋化石层位进行了详细厘定,对恐龙蛋类型进行了系统描述,并对前人报道的一些属种进行了分类订正.研究显示,天台恐龙蛋化石群基本上可分为7蛋科、12蛋属和15蛋种,代表了我国晚白垩世早期的恐龙蛋化石组合.本文简要报道了主要产自天台盆地赤城山组的双塘似蜂窝蛋(新蛋属、新修订种)、木鱼山半蜂窝蛋(新蛋属、新蛋种)、国清寺副蜂窝蛋(新修订种)、天台棱柱形蛋(新修订种)和张头槽马赛克蛋(新蛋属、新修订种)等3新蛋属、5新蛋种和修订种的主要鉴定特征,并建立一新蛋科——似蜂窝蛋科.
