A new ammonite genus, Khetoceras (Craspeditinae), is proposed, showing an atypical combination of features for the subfamily (arrowlike cross-section and prominent constrictions). A new subfamily Subcraspeditinae is proposed within the family Craspeditidae. An increase in whorl overlap was the major trend in the evolution of the Late Volgian subfamilies belonging to Craspeditidae. Platform, North and West Siberia and East Greenland with the ammonite Hectoroceras kochi provides an important correlation event of the Boreal Berriasian. Zakharov () regarded the B. okensis Zone as appearing in mid-Chetaites sibericus Zone and lasting until the middle of the succeeding H. kochi Zone. Hoedemaeker ().

The stratigraphy of the Volgian in Spitzbergen is refined based on the new fossil collections. The lower Volgian is poorly characterized by ammonites being not subdivided into zones, and the only recognized stratigraphic unit within it are the Beds with Paravirgatites sp.

Cenomanian strata in Northern Ireland are restricted to south and east Antrim, and crop out between Collinwell and Glenarm. They form a thin, highly condensed succession, up to 20 m in thickness and comprising the lower part of the Hibernian Greensands Formation, which underlies the Ulster White Limestone Formation.

Bulletin Geological Society Denmark, An ammonite-based correlation of Toarcian-Aalenian successions of the eastern Alborz with time-equivalent strata of the Lut Block, part of the Central-East Iranian Microcontinent (ca. km to the south), suggests a strong influence of synsedimentary tectonics during the deposition of the upper Shemshak Formation.
The excavations for drainage improvement of the Fenlands unexpectedly yielded new horizons rich in ammonites from the lower parts of the Sandringham Sands Formation, previously unseen; the initial discovery was near West Dereham, Norfolk ().Surprising amongst these ammonites were abundant specimens of the genus Hectoroceras, until then only known from Jameson Land, East Greenland.
Jurassic/Cretaceous boundary deposits in the Far East of Russia are characterized by fauna of a mixed type, including Tethyan ammonites and Boreal species of the north of the region (Western Okhotsk area), the middle Volgian deposits comprise the upper Tithonian Southern Primorye, the lower Berriasian ammonites Pseudosubplanites cf.
