= Bonata = Bonata is a soft-bodied, invertebrate, marine organism from the Ediacaran period(635 to 541 MA) and was found on the coast of the White Sea in Russia. Mikhail A. Fedonkin discovered and was the initial publisher of this fossil.

Morphology, Anatomy, & Behavior
The Bonata species can be described as having a round/oval body with two concentric zones. The most outer zone is somewhat flat. The inner zone consists of many wedge-shaped lobes with rounded ends, these lobes do not reach/meet in the center of the organism(indicating the animal had some depth to it). The diameter of the body can reach up to 40 mm while the diameter of the central zone is usually around 8-10 mm. There are usually 11-19 lobes that can reach up to 5 mm in length. It can be inferred that it is soft-bodied with fairly elastic edges(inferred by the crumbling/edges are folded). A small mouth is located in the middle of the inner zone.

Method of Fossilization
Bonata casts have been found as positive hyporeliefs in a claystone/claystone-siltstone composition.

Distribution & Paleoenvironment
The Bonata organisms’ existence ranged from 635 to 541 MA, or described as the Ediacaran period in the Proterozoic eon. The fossils have been found in the Ust’-Pinega Formation (Valdai Group). This specific rock unit is located in Zimnii Bereg coast on the White Sea, Russia. The rock composition of a claystone/claystone-siltstone mixture can infer the organism lived on the ocean floor(benthic) or near gentle flowing currents (such as a delta or river floodplains).

Other Notable Characteristics
The inner zone of the Bonata can be compared to the Peytoia nathorsti from the Middle Cambrian, which was found in British Columbia, Canada. The features that differentiate it was the lack of tetraradial symmetry and by the broad outer zone.
