Descripción
Mosasaurs were large predatory lizards that typically inhabited warm, epicontinental seas during the last 20 million years of the Mesozoic Era. Evidence of their taxonomic diversity derives mainly from significant finds from Late Cretaceous rocks of North America, Europe, and northern Africa (e.g., Russell, 1967; Lingham-Soliar, 1991, 1992; Bell, 1997). In contrast, the mosasaur record from the Southern Hemisphere is partial and much less informative (e.g., Welles and Gregg, 1971; Wiffen, 1980, 1990; Páramo, 1994; Bell et al., 1998; Caldwell and Bell, 1995; Gasparini et al., 2001). Mosasaur remains from Antarctica are mostly limited to isolated teeth and fragmentary bones (Gasparini and Del Valle, 1981, 1984; Chatterjee and Zinsmeister, 1982), thus restricting their potential implications for mosasaur phylogeny and paleobiogeography. Here we report on a new tylosaurine mosasaur, Lakumasaurus antarcticus gen. et sp. nov., discovered in the Late Cretaceous beds of James Ross Island, northeast Antarctic Peninsula. Lakumasaurus is the most complete mosasaur yet recorded in Antarctica, thus providing insights on mosasaur diversification in the southern seas. This discovery, together with Late Cretaceous mosasaur remains from New Zealand, suggests that distinctions between Cretaceous marine reptile faunas of the Southern and Northern hemispheres were greater than has been thought.
