Abstract��
The aquatic angiosperm mega- fossils Cobbania (Lesq�� ) Stockey et al�� are found from Upper Cre- taceous Yong'ancun Formation in Jiayin for the first time�� The new discovery has renovated the knowledge on the composition of the Santonian flora from the Yong'ancun Formation��and the geological range of Cobbania in Jiayin area�� Analyzing the floristic structure of Cobbania and its paleoenvironment��provides new data for the study of pa- leogeography and paleoenvironment of Jiayin��Heilongjiang��during the middle Late Cretaceous time�� |
