This volume of Fossils and Strata contains two contributions:

Coniacian and Santonian Belemnite Faunas from Bornholm, Denmark:
The belemnite faunas of the Lower-Middle Coniacian Arnager Limestone and Upper Coniacian – Lower Santonian Bavnodde Greensand Formations of the island of Bornholm, Denmark, are described, using biometric analysis. The fauna of the Arnager Limestone Formation includes four taxa: Actinocamax verus cf. antefragilis Naidin, new for Bornholm, Goniocamax lundgreni lundgreni (Stolley), Goniocamax sp.nov.(?) aff. lundgreni, and Goniocamax(?) sp.nov.(?). The fauna of the Bavnodde Greensand Formation is remarkably diverse and comprises nine taxa: Actinocamax verus verus Miller, Gonioteuthis praewestfalica Ernst & Schulz, new for Bornholm, Gonioteuthis westfalica westfalica (Schlüter), Gonioteuthis ernsti sp.nov., Goniocamax lundgreni lundgreni (Stolley), Goniocamax birkelundae sp.nov., Goniocamax striatus sp.nov., Belemnitella schmidi sp.nov., and Belemnitella propinqua propinqua (Moberg). Three belemnite zones and eight belemnite assemblage zones are recognized. The Coniacian has a Zone of Goniocamax lundgreni and includes three assemblage zones. The Lower Santonian has a Zone of Gonioteuthis praewestfalica below and a Zone of Gonioteuthis westfalica above. The lower zone is subdivided into two and the upper zone into three assemblage zones. The belemnite faunas include species from the Central European and Central Russian Subprovinces of the North European palaeobiogeographical Province. A major faunal turnover of the belemnite faunas takes place at the base of the G. westfalica Zone. Goniocamax lundgreni predominates below and Gonioteuthis westfalica above.

Santonian to Maastrichtian Ammonites from Scania, Southern Sweden:
Eighteen genera of ammonites are recorded from the Santonian to Maastrichtian rocks of Scania in southern Sweden. Ammonites are fairly common in the Vomb Trough, rare in the Kristianstad Basin and not recorded from the Båstad Basin. The chronostratigraphical assignment of the outcrops on ammonite and belemnite evidence is in agreement.
