New Campanian kossmaticeratid ammonites from the James Ross Basin, Antarctica, and their possible relationships with Jimboiceras? antarcticum Riccardi
Field work on James Ross Island, Antarctica, has resulted in the finding of a new upper Campanian ammonite fauna, which in SE James Ross Island includes in stratigraphic succession: a) Neokossmaticeras redondensis gen. et sp. nov., recorded in the upper part of the Rabot Formation, and b) Neograhami...
