 The "Cistecephalus" Assemblage Zone, from where "Euchambersia" is known, represents a floodplain that was covered in many small, relatively straight streams.The water level in these streams was probably seasonally dependent.Judging from pollen preserved in the "Cistecephalus" AZ, the pollen taxon "Pityosporites" (which probably originated from a plant similar to "Glossopteris") was very common, forming some 80% to 90% of the pollen discovered (although the prevalent sediments would not have been ideal for pollen preservation).
