Arboreomorph

The arboreomorphs (Arboreomorpha) are ediacaran organisms 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. It was previously included within Rangeomorpha, but later removed when more related forms were found.
