Ungulates (artiodactyls and perissodactyls) were identified as producers, whereas neither dolphins nor white whales (Delphinapterus) emitted methane (Table 1).
The Siwalik Group rocks constituting the Sub-Himalayan hill ranges have long been known to yield rich Neogene to Quaternary vertebrate fossil assemblages that represent dominantly mammalians fauna of multiple lineages, including rodents, artiodactyls, perissodactyls, proboscideans, carnivores and occasionally but of critical significance hominoid primates (Barry et al., 2002; Siddiq et al., 2014).
For example, arid conditions are reflected in the presence of Hispanotherium matritense or Anchitherium cursor, two perissodactyls with hypsodont dentition and relatively gracile limbs that are adapted to open and arid conditions (Cerdeno and Nieto, 1995; Soria et al., 2000; Salesa et al., 2001; Hernandez Fernandez et al., 2003), or several members of the order Rodentia, such as Armantomys, Microdyromys, Democricetodon or Cricetodon (Weerd and Daams, 1978; Meulen and de Bruijn, 1982; Daams and Meulen, 1984; Mein, 1983; Sese et al., 1985).
