Abstract: The fossil record of cranial material from titanosaurid sauropods is very poor and no complete skull has been described so far. Here we describe a new braincase (MUCPv-334) that was recovered from reddish sandstones of the Rio Colorado Subgroup (Late Cretaceous) of the region of Bajo del Añelo, approximately 20 km north of the town Añelo (Neuquén Province, Argentina). This specimen is attributed to the Titanosauridae based on the ventrally projected basipterygoid processes, a common condition shared by other t… Show more

“…There are no other described Argentinean sauropod endocasts, although new discoveries of titanosaur braincases have dramatically increased in the past decade (e.g., Calvo and Gonzalez Riga, 2004; Martinelli and Forasiepi, 2004; Calvo and Kellner, 2006; García et al, 2008; Filippi and Garrido, 2008; Filippi et al, 2011). In this study a detailed description of the endocranial morphology of Bonatitan , Antarctosaurus, and the unnamed titanosaurid MGPIFD‐GR 118 is provided, including the first observations on the inner ear morphology of the two first taxa.…”

“…Particularmente en Argentina, se describió en detalle la neuroanatomía del dicraeosáurido Amargasaurus Paulina Carabajal et al, 2014), el rebaquisáurido Limaysaurus (Calvo y Salgado, 1995;Paulina Carabajal y Calvo, 2015) y numerosos titanosaurios incluyendo Antarctosaurus, Bona-titan, Narambuenatitan, Saltasaurus y varios neurocráneos aislados (e.g., Calvo y Kellner, 2006;Paulina Carabajal y Salgado, 2007;García et al, 2008;Paulina Carabajal et al, 2008;.…”

“…A concavity on an indeterminate titanosaur braincase (MUCPv 334) described by Calvo and Kellner (2006) as a 'basisphenoidal depression' appears to be comparable with the single fossa on the posterior surface of the basal tubera of Saltasaurus. This concavity on MUCPv 334 is considered to be located on the ventral margin of the basal tubera (e.g., Mannion 2011).…”

“…Around the world, there are only a few titanosaur with some complete skulls, such those of Nemegtosaurus mongoliensis (Nowinsky 1971), Rapetosaurus krausei (Curry rogers and Forster 2004), Sarmientosaurus musacchioi (Martinez et al 2016), Malawisaurus dixeyi (haughton 1928) and Tapuiasaurus macedoi (Zaher et al 2011) and several complete embrionyc titanosaur skulls (Chiappe et al 2001. Moreover, there are other papers related to less complete cranial materials such as either partial cranium or basicranium in Saltasaurus loricatus (Bonaparte and Powell 1980), Quesitosaurus orientalis (Kurzanov and Banikov 1983), Muyelensaurus pecheni (Calvo et al 2007a), a surangular, angular, prefrontal and teeth in Rinconsaurus caudamirus (Calvo and riga 2003), teeth in Ampelosaurus atacis (Le Loeuff 1995, Alamosaurus sanjuanensis (Kues et al 1980) a postorbital and teeth in Quetecsaurus rusconii (Gonzalez riga and Ortiz 2014), some teeth in Alamosaurus sanjuanensis (Kues et al 1980), a basicranium and teeth in Mongolosaurus haplodon (Gilmore 1933, Mannion 2010, a Maxilla in Maxakalisaurus topai (Kellner et al 2006) and in Dreadnoughtus schrani (Lacovara et al 2014), in several unnamed basicraniums (Le Loeuff et al 1989, Tidwell and Carpenter 2003, Calvo and Kellner 2006, García et al 2008, and several maxilla (Calvo et al 2014, Sciutto and Martinez 1994.…”
