| Abstract |
New records of rare and/or poorly known scaphitid ammonites are presented from the basal upper Maastrichtian (Upper Cretaceous) white chalk exposed at Chelm quarry, Lublin Upland (eastern Poland). The described and illustrated material comprises four specimens, all preserved as composite moulds, and includes a well-preserved microconch of Hoploscaphites schmidi (BIRKELUND, 1982), fragmentary specimens of H. felderi KENNEDY, 1987 and Acanthoscaphites (Euroscaphites) varians blaszkiewiczi JAGT, KENNEDY & MACHALSKI, 1999, as well as a pathological macroconch of Hoploscaphites constrictus lvivensis MACHALSKI, 2005b. |
