Here at the blog we were first introduced to the American urinal by Aryeh here then the taxonomy was clarified by Eli here. I would like to do my part by classifying a few more exotic urinals. The britanias urinalas clearly classified under urinalas cornu, it is speculated that the ones found in america are actually invasive species escaped from british ships with segregated toilets (restrooms).
A urinal normally found in France, urinalés corné
Nearly extinct, I found this one living in the basement of the University of Leicester, urinalas grosses.
This is a fossilized toilet from Perivel Castle . . . carefull!
