Oldhamia

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]

  • O. antiqua Forbes, 1848
  • O. flabellata Aceñolaza et Durand, 1973
  • O. curvata Lindholm et Casey, 1990

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.
