- Abstract
Here we describe the Tribrachidium and Albumares Ediacaran organisms belonging to phylum Trilobozoa in the Sonia Sandstone of Marwar Supergroup, western India. Between the two Ediacaran genera, Albumares brunsae was the first to be discovered in India, while Tribrachidium heraldicum was the first record from the Marwar Supergroup. T. heraldicum is soft-bodied, discoidal or disc-shaped (in plane view) and slightly conical-shaped (when found with up to 2 mm vertical relief) with three elevated lobes (arms) or ridges bounded by a well-defined peripheral ring. A. brunsae is soft-bodied, flattened, low-relief, circular to sub-circular and with a tri-lobed (three elevated arms/rays) shield having branching rays that radiate outward from the centre to the outer edge of the peripheral ring. Both Ediacaran taxa occur here as convex or positive reliefs with triradial symmetry on medium to fine-grained sandstone bedding planes in the Sursagar area and show the Flinders Ranges style of preservation.
