Dental and vertebral morphology of the enigmatic mosasaur Dollosaurus (Reptilia, Mosasauridae) from the lower Campanian (Upper Cretaceous) of southern Sweden

Summary, in English
Teeth, jawbone fragments and vertebrae of an unusual mosasaurine mosasaur, Dollosaurns, have been collected from marine strata of latest early Campanian age in the Kristianstad Basin, southern Sweden. This material enables a detailed analysis of dental and vertebral characters, which, in turn, are used to tentatively distinguish Dollosaurus from the closely related globidensine Prognathodon. However, the evidence is contradictory, and two evolutionary scenarios are possible: (1) the two genera represent separate offshoots of a single lineage; or (2) Dollosaurns represents the most basal 'Prognathodon-like' taxon known so far.
