In life, C. geognostica was a long-snouted pelagic fish, superficially similar to the Australian Rolfosteus, from Gogo Formation and the European Oxyosteus of the Kellwasser facies of Bad Wildungen, Germany. As with Rolfosteus, Carolowilhelmina possessed a long tubular rostral plate, with small postnasal plates and low inferognathal plates. According to Mark-Kurik & Carls (2002), this placoderm may have lived in a pelagic environment with lush, floating algae and epiplankton. It is currently known only from an incomplete cranium that is about {{convert|40|cm|abbr=on}} 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). Sources
