Bad Wildungen
"R. traquairi" and "R. tuberculatus" are both endemic to Bad Wildungen. "R. parvulus" is also found in Bad Wildungen. Rücklin (2011) discusses how specimens of small "Rhinosteus" have been found in the Kellwasserkalk facies of the Anti-Atlas of Morocco, and are tentatively referred to "R. parvulus" due primarily to their small size.
