摘要
本文首次全面报道了产于浙江象山县爵溪镇下沙、大岙和岱山县大长涂岛小沙河中全新世海滩岩中的动物群，计有４３属５４种贝类和７属１０种有孔虫，８属８种介形类。进行了生态类型的划分和古今对比研究，认为与当地现生动物群有明显差别；发现了１６种热带贝类，而有孔虫、介形类未见冷水种，揭示了中全新世时当地气候比现今温暖，也证实了浙江海滩岩是中全新世热带环境条件下的产物。
Faunas of Mid-Holocene beachrocks at Xiasha and Da’ao of Juexi Town,Xiexi Town,Xiang-shan County and at Xiaoshahe of Dachangtu Island,Daishan County in Zhejiang Provinceare reported in the paper. 43 genera and 54 species of conchs,7 genera and 10 species offoraminiferas,and 8 genera and 8 species of ostracodas are found.It is different to the lo-cal present-day faunas,15 genera and 16 species of those conchs are of tropical origin.Results of the study indicate that Mid-Holocene climate was warmer than now.
