I was give these two pieces by a frirend who cliamed they are both from the same Shanxi formation ( lower permian, like missisippi in US) in Yangquan, a well known coal mine in North China. He said they are just two pierces of the same thing ( Lepidodendron oculus felis). I found it hard to swallow, as the two pieces look rather different. however after some digging into literrature, it seems he is backed by many old scholars (not all, though) including Kawasaki, Stockmans and Mathieu. The last two pics I got from an old book, which look rather similar to mine, are considered by these researchers as belonging to the same species, although they are rather far between in loacation and age ( from upper carbon to upper permian). please enlighten me.
