''Indocetus'' is a protocetid early whale known from the late early Eocene (Lutetian, ) Harudi Formation (, paleocoordinates )〔. Retrieved July 2013.〕 in Kutch, India. The holotype of is a partial skull in two pieces with the frontal shield and the right occiput and auditory bulla preserved. described postcranial remains from the Sulaiman Range, Punjab, Pakistan, and attributed them to ''Indocetus''. , however, withdrew this assignment and instead attributed this postcranial material to ''Remingtonocetus'' because of similarities to the then newly discovered remingtonocetid ''Dalanistes'', including a longer neck and fused sacral vertebral elements. This leaves ''Indocetus'' without postcranial remains, but undescribed material (as of 1998) from Kutch most likely include some that can be attributed to ''Indocetus''. Furthermore, ''Rodhocetus'', also from Sulaiman, is very similar to ''Indocetus'' and it is possible that these genera are synonyms. ''Indocetus'' is known from a partial skull, two endocasts, a right tympanic, and a right maxilla; all from the Harudi Formation. ''Indocetus'' has prominent protocones on the molars, distinguishing it from ''Protocetus'', ''Eocetus'', ''Babiacetus'', and ''Georgiacetus''. P1 is single-rooted like ''Rodhocetus''. The tympanic bulla is more narrow than in ''Protocetus'' and ''Georgiacetus''. The endocasts included dental material, including alveoli and the bases of cheek teeth but not the crowns. P3–4 are three-rooted and probably had protocones. The molars are smaller than the premolars and decrease from M1 to M3. M1 and M2 have large protocone lobs.〔 ==Notes== 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Indocetus」の詳細全文を読む スポンサード リンク
