- Abstract
The present study reports the well-preserved Ediacaran sack-like soft-bodied fossils assigned as Finkoella ukrainica and Finkoella oblonga from the Sonia Formation of the Jodhpur Group, Marwar Supergroup, western Rajasthan, India. The F. ukrainica is found in elliptical, ovate-shaped and sometimes oblong or cucumber-shaped forms with a distinct short neck, and a small circular protrusion or depression may be present on the organism. F. oblonga is elongated, ovate to cucumber-shaped fossil specimen with poorly preserved six longitudinal low grooves and ridges arranged parallel to the marginal ridges of the organism. Both F. ukrainica and F. oblonga are also well comparable to the type materials of Ukraine in the preservation of concave (negative relief) and convex (positive relief) with oral/atrial siphons, double marginal ridges/grooves and elevated edges in the Sonia Formation. The Finkoella fossil remains are believed to be the flattened bodies of tunicate organisms. Similar sack-shaped Burykhia fossils recorded in the White Sea of Russia contrasted to sponges and similar hollow-shaped organisms have been interpreted and compared with lichenized fungi and fungal affinity. Thus, the biological affinity of the Finkoella organism is still unresolved.
