Grandilingulata

Grandilingulata is a Calymmian organism, found in the Gaoyuzhuang Formation of China. It has been tentatively placed inside Eukaryota due to its complexity and size, alongside other fossils from the formation.

Description
Grandilingulata is a tongue-shaped fossil, growing up to 30 cm in length and 4 cm in width. As it dates from the earliest Mesoproterozoic, its exact classification is unknown beyond a probable eukaryotic affinity.

Etymology
The genus name Grandilingulata means "large tongue", referring both to its tongue-like shape and its large size for organisms of the time period. The specific name qianxiensis refers to the location of a newly discovered fossiliferous location in Qianxi County, Hebei.
