New Mosasaur remains from the Upper Cretaceous of Mississippi

New discoveries of fossil teeth from mosasaurid reptiles are reported from Late Cretaceous
strata in northeastern Mississippi, USA. The new material is attributed to the mosasaurine Mosasaurus
hoffmannii and the russellosaurines Tylosaurus sp., Plioplatecarpus sp. nov., and cf. Platecarpus. Fossil
specimens originate from the Campanian of Lee and Prentiss Counties and the Maastrichtian of Union
County.
