Species
The type species, E. aegyptiacum, is known from the
Several other species have been named, including E. babiae from India,[4] E. majus, E. clavigerum and E. sandersi from Egypt,[5][6] and E. waghapadarensis, also from India.[7] E. majus was based on a single upper molar, which was never catalogued and is now lost;[6] it has been considered a senior subjective synonym of E. aegyptiacum.[8]
Paleobiology
The teeth of Eotheroides were relatively unspecialized compared to those of extant sirenians, which are reduced as an adaptation for feeding on sea grass. The upper molars of E. lambondrano are considerably longer and wider than those of E. aegyptiacum, suggesting that they were less specialized.
