Karakhtia nessovi is a species of Proarticulate from the Ediacaran period, around 555 Million Years Ago.

[2] The holotype fossil of Karakhtia was found from the Ust-Pinega Formation, in the White Sea of Russia, and described in 2004.

[1] The generic name Karakhtia is derived from the place name Karakhta River, near to where the fossil material was found.

The specific name nessovi is derived from the surname of L.A. Nessov, a Leningrad paleontologist.

Unlike anything seen other Proarticulates, it features a margin with radial folds, giving it a frilly appearance.
