Carolowilhelmina geognostica is an extinct arthrodire placoderm fish that lived in the Late Eifelian epoch (of Middle Devonian) of Aragon, Spain. In life, C. geognostica was a long-snouted pelagic fish, superficially similar to the Australian Rolfosteus and the European Oxyosteus. It is currently known only from an incomplete cranium that is about long. The fossil material is housed in the Natural Sciences museum of the University of Zaragoza, Spain (Museo de ciencias Naturales de la Universidad de Zaragoza).

== Discovery == Initial fragments belonging to Carolowilhelmina were accidentally uncovered by paleontologist Peter Carls in April 1971, after breaking a limestone nodule in an attempt to obtain a Conodont sample. The following day, fellow paleontologist Otto H. Walliser identified the fragments as fish remains, as they had been washed clean by a creek below the section. The origin of the fragments, however, could not be identified, as a portion of the slope had slid down and covered it. This did prompt a search for fish remains elsewhere, resulting in the discovery of Grossius aragonensis. by 1986, the creek had eroded at the sediment, revealing part of the fossil's rostrum. The fossil was collected in 1993.
