Resumen:
Novas et al. (2002. Ameghiniana 39:245249) described and named a new mosasaur as Lakumasaurus antarcticus from the Late
Cretaceous marine deposits of the Antarctic Peninsula. The specimen was recovered from the late Campanian Santa Marta
Formation on James Ross Island. A number of characters indicate the affinities of Lakumasaurus with the Tylosaurinae.
However, other characters of Lakumasaurus are unusual among tylosaurines, particularly the dentition bearing fine striae, teeth
with non-serrated anterior carinae, anterior teeth without posterior carinae, relatively straight lateral margins on frontal and
relatively small size. Investigation of mosasaurs from New Zealand confirms that these characters occur in the type specimen of
with non-serrated anterior carinae, anterior teeth without posterior carinae, relatively straight lateral margins on frontal and
relatively small size. Investigation of mosasaurs from New Zealand confirms that these characters occur in the type specimen of

The synonymy of Lakumasaurus with Taniwhasaurus adds significantly to the evidence of endemism among marine reptiles
in Antarctica, New Zealand and Patagonia (Weddellian Province) during the Late Cretaceous. Taniwhasaurus along with the
possible co-occurrence of Moanasaurus are the first mosasaurs at a generic level to indicate Gondwanan endemism. The
mosasaur evidence is complemented by the plesiosaur Aristonectes, which occurs in the Maastrichtian of Argentina and
