Summary

Description

Inzeria intia Walter, 1972 - fossil stromatolites from the Precambrian of Australia.

The multiple branching columnar structures seen here are stromatolites. They are built up by mats of cyanobacteria. Stromatolites vary in appearance, ranging from slightly wrinkled horizontal laminations in sedimentary rocks to low mounds to prominent mounds to columnar structures and other forms. Stromatolites are most common in the Proterozoic fossil record. They are scarce today, but famous modern examples occur at Shark Bay, Western Australia.

Stratigraphy: probably the Bitter Springs Formation, Neoproterozoic, cited as ~800 Ma

Locality: unrecorded/undisclosed site attributed to Bitter Springs (but probably from near Alice Springs), Northern Territory, northern Australia
