Geologic formation in China
The Gaoyuzhuang Formation is a geologic formation in China. It preserves fossils dating back to the Calymmian period of the Mesoproterozoic. It is one of the first formations to preserve definitive macroscopic eukaryotes, at almost 1.6 billion years old. In addition to this, the site preserves a diverse microbiota with various cyanobacteria and fungus-like fossils known.

In addition to these fossils, five unnamed forms are also known. Forms A and B are only known from one specimen, Form C is too fragmentary to be named, and Forms D and E bear no resemblance to any plant, prokaryote, animal or protist. However, various hyphomycetous fungi do form similar structures to forms D and E, thus they may be within this group.
