“…The genus Lewesiceras is known from the North European Province of the Boreal Realm and from the Northern Transitional Subprovince (Poland, the Czech Republic, Germany, France, Great Britain, Spain, Romania, Bulgaria, S Sweden), but it has also been reported from other regions such as the Pacific Province or Tethys Province (Japan, Montana (USA), Madagascar, North Africa, S India, Russia) and Asia (Crimea, Causasus, Kazakhstan) (Moore, 1968;Kennedy & Wright, 1979;Matsumoto, 1979;Kennedy & Wright, 1981, Čech, 1989Lamolda et al, 1989, Tarkowski, 1991Kaesler, 1996;Marcinowski et al, 1996;Wiese & Kaplan, 2001;Ion et al, 2004;Košt'ák et al, 2004;Wiese et al, 2004;Ekrt et al, 2008). The genus Lewesiceras is known from SE France and this confirms migration of this boreal ammonite, during a cooling phase in the late Middle Turonian, in a southern direction (Wiese & Voigt, 2002;Košt'ák & Wiese, 2011).…”
