Biology:Nilpenia
Nilpenia rossi is an Ediacaran sediment feeder,[1] with specimens only having been described in the Flinders Ranges of South Australia. With a diameter ranging up to 30 cm, it is considered to represent the largest (by area) Ediacaran organism.[2]
Morphology
Nilpenia fossils consist of two zones, a complex central area surrounded by radiating, branching groove structures. Larger specimens have densely packed grooves. They are interpreted to have uniquely lived millimeters above the actual sediment, opposed to views of how other organisms were mat-encrusters, which interacted within microbial mats on the seafloor.
History
Nilpenia was first discovered in 2013 at the Ediacara Member of the Rawnsley Quartzite, Flinders Ranges in South Australia.
