摘　　要：腹足类化石在地层中丰富且常见,但在琥珀中保存较少。文中描述了产自白垩纪中期缅甸琥珀中的陆生腹足类化石2属2种:Euthema naggsi Yu,Wang and Pan,2018,Truncatellina dilatatus sp.nov.。这些陆生腹足类新材料的发现,提高了缅甸琥珀中陆生腹足类物种多样性,并进一步印证了白垩纪中期缅甸琥珀森林温暖潮湿的热带雨林环境。Gastropod fossils are abundant,but they are rarely preserved in amber.Two genera and two species of terrestrial gastropods Euthema naggsi Yu,Wang and Pan,2018,Truncatellina dilatatus sp.nov.are described from mid-Cretaceous amber from northern Myanmar.Our findings offer more complete records of palaeontological diversity of terrestrial gastropods preserved in Burmese amber.The ecological context of amber gastropods further confirms the warm and humid tropical rain forest environment of the amber forest in the mid-Cretaceous.
