Gregicaulis dubius

Pleuromeia dubia is a tall species for the genus, with distinctive elongate leaf scars, and known from the Early Triassic of Australia and South Africa. Like other species of Pleuromeia it was a survivor of the marked greenhouse spike at the end of the Early Triassic.[1] It was originally assigned to the genus Gregicaulis, and its placement in the genus Pleuromeia has been questioned, due to its significant differences to the core Eurasian members of the genus.[2]
