_Globidens_. A very special, malacophagous (=durophagous) mosasaur
that probably fed on bivalves. Ask Mike Everhart - he has photos of
specimens on his web site: I have seen specimens in Maastricht. There
is another ball-toothed mosasaur, _Igdamanosaurus_, from
Nigeria, but if I remember correctly this is not regarded as closely
related to the globidentines. Nick has a point - most other
durophagores have flattened teeth that form a 'pavement'.
