Kulparia is a genus of fossil stromatolite-forming cyanobacteria from the late Neoproterozoic era. It is named after the town of Kulpara in South Australia, where the type specimen was found nearby.[3][4]

Description

[edit]

Kulparia is a genus of cyanobacteria known from fossil stromatolites characterised by long, bumpy, almost straight columns arranged radially or parallel. Branching between columns is α- or β- parallel. Bridging and coalescing are very frequent, a wall between bridges is almost always present. Projections are moderately frequent to rare.[3][4][5]

The stromatolites of Kulparia appear similar to Minjaria and Boxonia in gross form but is distinguished by its bumpy column margins and frequent bridging and coalescing.[3]

Taxonomy

[edit]

K. kulparensis was initially assigned to the genus Patomia as Patomia sp. nov (Glaessner, Preiss, & Walter 1969) but was later assigned to its own genus where it became the type species.[3][4]

Two species are recognised, K. kulparensis,[4] and K. alicia.

Distribution

[edit]

Fossils of K. kulparensis have been found in the Umbertana Group in the northern Yorke Peninsula in South Australia, 4 miles (6.4 km) south of Kulpara.[4]

K. alicia fossils have been found in the Loves Creek Member of the Bitter Springs Formation in the Amaedus Basin of Western Australia, 2.3 miles (3.7 km) west-south-west of Jay Creek Aboriginal Settlement.[3]
