Ichnogenus OldhamiaForbes, 1848 | ||
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.
The Ediacaran species Oldhamia recta are body fossils of a rod-like organism, rather than ichnofossils.
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.
