Its ribbing is distinct, consisting of both simple and bifurcated ribs that extend from the umbilical seam across the venter; its whorl section generally compressed, the venter more or less narrowly rounded. Berriasella, named by Uhlig, 1905, is known from the late Upper Jurassic, Tithonian, to the early Lower Cretaceous, Berriasian and has a fairly worldwide distribution.[2]References1. ^{{cite journal|last=Sepkoski |first=Jack |title=A compendium of fossil marine animal genera (Cephalopoda entry) | journal=Bulletins of American Paleontology |volume=363 |pages=1–560 | year=2002 | url=http://strata.geology.wisc.edu/jack/showgenera.php?taxon=231&rank=class |accessdate=2017-10-18 |deadurl=yes | archiveurl=https://web.archive.org/web/20160225225905/http://strata.geology.wisc.edu/jack/showgenera.php?taxon=231&rank=class | archivedate=2008-05-07 |df= }} 2. ^Paleobiology Database - Berriasella at Fossilworks.org Further reading
