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.[1]
Grandilingulata is a tongue-shaped fossil, growing up to 30 cm in length and 4 cm in width.[2] As it dates from the earliest Mesoproterozoic, its exact classification is unknown beyond a probable eukaryotic affinity.
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.[1]
