ABSOLUT SELTEN ! RARITÄT!
Karakhtia nessovi is a species of proarticulatefrom the Vendiidae family, growing up to 100 mm (3.9 in) in length, and like other members of its family, it has a headshield-like structure. Unlike anything seen in other proarticulates, it features a margin with radial folds, giving it a frilly appearance. It emerged in the Ediacaran period, around 555 Million Years Ago. K. nessovi is the only species in the genus Karakhtia. The genus Haootia has been compared minorly to Karakhtia in the way that the fossils of Haootia superficially resemble the crumpled margins of Karakhtia.
