First record ofOphthalmosaurus(Reptilia: Ichthyosauria) from the Tithonian (Upper Jurassic) of Mexico

Abstract: From the Middle Jurassic on, the Tethys basin opened westward; the existence of a Carribean corridor linking the European and Pacific realms now appears well supported by comparison of marine reptile assemblages (e.g., Gasparini and Fernández, 1997, 2005; Gasparini et al., 2000; Fernández and Iturralde-Vinent, 2000; Gasparini and Iturralde-Vinent, 2001, 2006; Gasparini et al., 2002). Marine transgression in Mexico began during the Callovian, as evidenced by the evaporites of the Minas Viejas Fm. However, micro… Show more

“…The teeth are close to the size range of those found in Ophthalmosaurus cf. O. icenicus (Buchy 2010) and Sveltonectes insolitus (Fischer et al 2011). This is in contrast to the large teeth of Brachypterygius D r a f t 11 (McGowan 1976) or Platypterygius (Fischer et al 2011).…”

“…This genus has been described as having small, conical teeth [55,62] with a pointed apex bearing fine longitudinal ridges [63]. The size of the teeth suggests inclusion within Massare's [59] 'smash' guild, while the crown morphology is consistent with the 'general' guild.…”

“…[11]; (B) modified from Druckenmiller and Maxwell [9]. Ichthyosaurus communis and Ophthalmosaurus icenicus now extend into the Pliensbachian [69] and Tithonian [62] So, what do the divergent phylogenetic hypotheses tell us about the origins and evolution of Cretaceous ichthyosaurs? The radiation of Platypterygius [9] or the emergence of the Platypterygiinae [11] during the Late Jurassic could coincide with the opening of the Atlantic Ocean [70], or new dispersal routes through the breakup of Gondwana [71].…”

“…The slenderness of the rostrum does not match the robust jaws of Brachypterygius (McGowan, 1976), Mollesaurus (Fernández, 1999), and Platypterygius hercynicus (Kuhn, 1946;Kolb and Sander, 2009). The retention of small, yet robust, and pointed teeth at adult stage also differs from most post-Liassic taxa, which exhibit either toothlessness or a reduced number of very small and delicate teeth (Mollesaurus, Ophthalmosaurus, Caypullisaurus, Chacaicosaurus;McGowan, 1976;Fernández, 1994Fernández, , 1999Fernández, , 2007Buchy, 2010), or are characterized by medium-sized, recurved, robust teeth with an acute but rounded apex (Undorosaurus, Brachypterygius, Platypterygius; McGowan, 1972McGowan, , 1976Massare, 1987;Bardet, 1989Bardet, , 1990McGowan and Motani, 2003;pers. obs.).…”
