supports: The Cretaceous is a geologic period and system that spans 79 million years from the end of the Jurassic Period million years ago (Mya) to the beginning of the Paleogene Period Mya. It is the last period of the Mesozoic Era. The Cretaceous Period is usually abbreviated K, for its German translation "Kreide" (chalk). Desmoceratidae is a family belonging to the ammonite subclass. They are an extinct group of ammonoids, shelled cephalopods related to squid, belemnites, octopuses, and cuttlefish, and more distantly to the nautiloids, that lived between the Lower Cretaceous (Upper Valanginian) and Upper
  Cretaceous (Upper Maastrichtian). Uhligella is an extinct cephalopod genus from the Early Cretaceous belonging to the ammonoid subclass and included in the Desmoceratidae. A stratigraphic column is a representation used in geology and its subfield of stratigraphy to describe the vertical location of rock units in a particular area. The Barremian is an age in the geologic timescale (or a chronostratigraphic stage) between 129.4 ± 1.5 Ma (million years ago) and 125.0 ± 1.0 Ma). It is a subdivision of the Early Cretaceous epoch (or Lower Cretaceous series). It is preceded by the Hauterivian and followed by the Aptian stage. The Aptian is an age in the geologic timescale or a stage in the stratigraphic column. It is a subdivision of the Early or Lower Cretaceous epoch or series and encompasses the time from 125.0 ± 1.0 Ma to 113.0 ± 1.0 Ma (million years ago), approximately. The Aptian succeeds the Barremian and precedes the Albian, all part of the Lower/Early Cretaceous. Zurcherella is a Lower Cretaceous ( Upper Barremian - Upper Aptian desmoceratid ammonite . 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 .
