摘要

 
    

Some recently discovered fossil leaves of cycad from the Middle Jurassic Haifanggou Formation in Changlongdigou, Beipiao, Western Liaoning Province are summarily reported. This species of fossil plant was firstly described by Japanese researcher Yokoyama from the Middle Jurassic Dabao Formation of Nianzigou, Fengcheng, Eastern Liaoning Province. Later on, it was also found in Japan and England. Undoubtedly, these fossil plants are the best conserved so far for this genus in the Middle Jurassic Yanliao Flora. The present discovery of these specimens is significantly important for the paleoecology, paleoclimatology and other researches on the Yanliao Flora in China.
