Genera

The arboreomorphs (Arboreomorpha) are ediacaran beings of the frondomorph type that had a disk or bulb-shaped anchor on the ocean floor, a central stem and branching. The "branches" were smooth, tubular structures, often swollen with bifurcation and connected together to form a leaf-like structure.[1]

Thaumaptilon is considered as one of the few cases that reached the Cambrian,[2] though its placement is controversial.[3] Some authors classify this group within Rangeomorpha and others together with Erniettomorpha in a larger group called Frondomorpha.
