Chondroplon bilobatum is a medusoid Ediacaran fossil. It has sand-filled tubes, although these may not have been sand-filled in life. It has a shield-like shape, with one end different from the other, and bilateral symmetry, and although it has been suggested that it possesses glide reflection symmetry, such suggestions are based upon a taphonomic effect deforming some specimens. Chondroplon was originally described by Mary Wade in 1971 from fossils found in South Australia. It was named after chondrophores — chitinous floats found on some kinds of colonial floating hydroids.
In addition to the Ediacara Hills in South Australia Chondroplon is also found in the White Sea area of Russia . The host rocks in these areas have been dated as 555 million years old.
The original interpretation was that Chondroplon is a chondrophorine cnidarian.[1][2] It has also been interpreted as a deformed Dickinsonia.[3] The Vendobionta theory has them as "fluid–filled quilts". As with most of the Ediacaran biota, scientists are yet to reach agreement on a firm classification for this enigmatic fossil.
