Maenniligraptus Mierzejewski, 1985
Taksoni kirjeldused
Maletz, 2019b
The taxon is very poor and specifically indeterminate. Mierzejewski (1982) identified this material as a camaroid and suggested that similar organic material from pre-Devonian samples showing the inner rings and spiral thickenings may have been mistaken for tracheid-like tubes characteristic of land plants.
