lonchopteris rugosa Westphalian near Lens France

Wow the texture on this fossil is so sharp! Was it found in this condition or did you clean it up?

I just open(broke) the slab and discover,nothing else

@nala Normally, Lonchopteris shows anastomosing nervation. This specimen certainly doesn't. Could it be an Alethopteris instead?

You are right paleoflor,i mix the pictures it'an Alethopteris!this is a Lonchopteris 

Yes, and that last photo is a beautiful example of Lonchopteris venation!
