Zurcherella is a Lower Cretaceous (Upper Barremian - Upper Aptian desmoceratid ammonite from France and Colombia. Its shell is moderately compressed and rather involute, with fine sinuous ribs that arise some distance above the umbilical rim. Zurcherella differs from its descendant Uhligella in that in the latter, ribs arise from the umbilical shoulder.
