Psammornis rothschildi is an avian oospecies, the type material of which was collected from the desert surface in 1909 (i.e., without stratigraphic context), 20 miles east of Touggourt, Algeria. At 3.2–3.3 mm thick, the eggshell is considerably thicker than those of extant ostriches. Thin sections of the eggshell have been illustrated, and descriptions of the surface features are available, but these have not included images of the external and internal surfaces. This lack has caused uncertainty among authors who have dealt with other occurrences of the taxon, because it has rendered it difficult to compare specimens from other localities with the type material. In order to rectify the situation, images of the original specimens are provided, their curation history is summarised, and a lectotype is nominated so as to stabilise the nomenclature.
