looking for info on Protocalamites sp.

[Manticocerasman]

On the last few fieldtrips to the quarry in Southern Belgium where we look for goniatites we found quite a few plant remains in some of the anoxic marine deposits. A friend of mine thought that one of these remains could be Protocalamites sp. , but we find verry little info about that plant. Does anyone know when they first occurred?

 

The layer where we found the remains were from the Late Devonian: Frasnian – Matagne formation ( Upper rhenana conodont Zone )

Any comparison pictures or papers on this subject are welcome.

Protocalamites..., in discussion . Could you post a pic? Devonian plants are always interesting, early ones...
