【摘要】 圆盘青钱柳Cyclocarya scutellata Guo为郭双兴(1979)建立于海南岛长昌盆地长昌组的新种,但根据果柄、果的大小以及所谓的"翅脉"等特征,作者认为郭双兴(1979)建立的"圆盘青钱柳Cyclocarya scutellata Guo"并不成立,这类标本应是莲的果实的不同保存状态,不能归入Cyclocarya。因此,郭双兴(1979)提出的关于青钱柳属可能起源于海南岛始新世的推论也就缺乏化石依据。更多还原

【Abstract】 "Cyclocarya scutellata Guo" is a new species described by Guo(1979) from the Changchang Formation(Eocene) of the Changchang Basin on Hainan Island,China.But based on the fruit stalk,size,and so-called "winged venation",the authors think these specimens could be lotus fruit fossils representing different preserved states and should not be classified into Cyclocarya.Therefore,the proposition of Guo(1979) that Cyclocarya probably originated in Hainan Island in the Eocene epoch is not supported by the fossil record.更多还原
