“…Our coding of fossil bunodont otters depends both on our own observations of the specimens from the Siwaliks and on published sources: Pilgrim (1932), Grohe (2011) for Vishnuonyx; Peigne et al (2008), Grohe et al (2013) for Sivaonyx (S. gandakasensis, S. bathygnathus, S. beyi); Falconer (1868), Matthew (1929), Geraads et al (2011) for Enhydriodon (E. sivalensis, E. falconeri, E. dikkikae). Other fossil taxa included in our cladistic analysis are coded mainly based on illustrations and descriptions from the literature: Roman & Viret (1934), Helbing (1936) for Paralutra jaegeri; Willemsen (1983), Villier et al (2011) for Paralutra garganensis; Ginsburg et al (1983), Villalta & Crusafont-Pairo (1945), H€ urzeler (1987 for Tyrrhenolutra helbingi; Morales & Pickford (2005) for Paludolutra (P. lluecai, P. marammena, P. campanii); Berta & Morgan (1985), Lambert (1997) for Enhydritherium terranovae; Zdansky (1924) for 'Lutra' aonychoides). Finally, coding for extant lutrines and Siamogale is mostly based on our own examination of specimens and from Grohe et al (2010) and Grohe (2011).…”
