Manticocerasman Posted August 10, 2022 Share Posted August 10, 2022 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. growing old is mandatory but growing up is optional.
