Zurcherella

Zurcherella is a Lower Cretaceous (Upper Barremian - Upper Aptian desmoceratid ammonite from France and Colombia (Apón and Yuruma Formations, La Guajira). Its shell is moderately compressed and rather involute (outer whorls covering most of the inner), 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.
"Zurcherella" is the earliest of the desmoceratid subfamily Beudanticeratinae, which includes among others, "Uhligella", "Beutanticeras", and "Beutantiella".
