“…The bones remains have been related to Hadrosauridae indet (Casamiquela, 1964;Apesteguía and Cambiaso, 1999;Hill et al, 2002;Luna et al, 2003;Martinelli and Forasiepi, 2004;Cruzado-Caballero, 2014;Cruzado-Caballero and Coria, 2014), with the basal hadrosaurid Secernosaurus koerneri (Bonaparte et al, 1984;Prieto-M arquez and Salinas, 2010) and Lapampasaurus cholinoi (Ju arez-Valieri et al, 2010;Coria et al, 2012), and the hadrosaurine Willinakaqe salitranensis (Ju arez- Valieri et al, 2010;Coria, 2014). In Antarctica, hadrosaurids are limited to the Maastrichtian L opez de Bertolano Formation (Otero and Reguero, 2013). The fossil remains are fragmentary and scarce and were classified as Hadrosauridae indet (Rich et al, 1999;Case et al, 2000;Otero and Reguero, 2013).…”
