Abstract

A new species of the genus Worthoceras has been recognized in material from a borehole (Bóly-1) in southern Hungary. Worthoceras pygmaeum sp. nov. co-occurs with typical Upper Albian (Stoliczkaia dispar Zone) ammonites. It seems likely that the genus Worthoceras arose in early late Albian times in North America and migrated eastward (Europe). During the Cenomanian it reached the southern margin of Tethys (Madagascar, India). It reached its most widespread distribution in Turonian times (from North America to New Zealand) and then became extinct. Beside the increasing area and growing dimensions, the strengthened sculpture is characteristic of the Worthoceras evolution.
