In the Dobrudzha Basin, numerous specimens are found mainly in flood plain claystones and siltstones. The habitat and reconstruction of the plants suggests a creeping manner of growth. Climatic changes are reflected in the architecture of species. One specimen has an attached seed proving the classification of the genus as a pteridosperm.
