}}Lithacoceras is an extinct Ammonite cephalopod genus included in the superfamily Perisphinctoidea. These fast-moving nektonic carnivores lived during the Jurassic period, from the Oxfordian age to the Tithonian age.[1] DistributionFossils of species within this genus have been found in the Jurassic sediments of Antarctica, Argentina, Canada, Cuba, France, Germany, Madagascar, Somalia, Spain, United States and Yemen.[2] References1. ^1 {{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.ummp.lsa.umich.edu/jack/showgenera.php?taxon=231&rank=class |accessdate=2017-10-18 | deadurl=yes | archiveurl=https://web.archive.org/web/20080507014300/http://strata.ummp.lsa.umich.edu/jack/showgenera.php?taxon=231&rank=class | archivedate=2008-05-07 |df= }} 2. ^1 Paleobiology Database - Lithacoceras. 2017-10-19.
