Gibbavasis kushkii is a species of an enigmatic member of the Ediacaran biota from central Iran.

In 2018, Vaziri, Majidifard and Laflamme discovered Gibbavasis in Central Iran with their findings resulting Nine specimens preserved in Negative Epirelief.

These nine specimens were found in the grey argillaceous shales -sub-unit 6- of the Kushk Series from the Kushk Area (Chahgaz (Dargazin) locale, all of them being located in the Bafq region inside the Chahmir area in the Behabad region, located in Central Iran.

[2] These forms from Iran are examples of a Biosphere going through a transitional phase with evidence for this claim being the abundance and diversity of organisms from the large and mostly soft-bodied organisms (Ediacaran biota) to much more complex, mineralized and skeletonized tubular forms from the dawn of the early Cambrian.

[2] G. kushkii represents a form that is (morphologically) similar in anatomy to the Namibian Ausia, because A. fenestrata also possess the same external openings (or pores, since both have been interpreted as Poriferans).
