Oldhamia is an ichnogenus describing burrows produced by worm-like organisms mining underneath microbial mats. It was common from the Early Cambrian deep-water deposits.[1][2]

The Ediacaran species Oldhamia recta are body fossils of a rod-like organism, rather than ichnofossils.[3]

The Ordovician Oldhamia pinnata and Carboniferous-Permian Oldhamia fimbriata were mentioned without any ichnotaxonomical formalization, and therefore are nomina nuda.

It was named after the geologist Thomas Oldham.
