Theatonius FOX, 1976b

R e m a r k s: Known by isolated skull bones, Theatonius is distinctive among known Mesozoic anurans, yet its relationships are uncertain ( Fox 1976 b, Estes and Sanchiz 1982, Duellman and Trueb 1986, Roček 2000, 2013, Holman 2003, Gardner 2008, Blackburn and Wake 2011). Theatonius lancensis , the type and only described species in the genus, is best known from a small collection of isolated maxillae (including the holotype), squamosals, and frontoparietals from one locality (Bushy Tailed Blowout, Wyoming, USA) in the upper Maastrichtian (Lancian NALMA) Lance Formation ( Fox 1976b, Gardner 2008). An isolated maxilla currently referred to T. lancensis has been reported ( Gardner and DeMar 2013, Mercier et al. 2014), but not yet described, from the paracontemporaneous Hell Creek Formation in Montana, USA.
