Remingtonocetus was a small cetacean with
R. harudiensis weighing . interpreted
R. domandaensis as an older and more generalized species than
R. harudiensis. Based on a morphological analysis, they concluded that the hindlimbs of
Remingtonocetus were probably not weight-bearing, and that (1) the fused sacrum indicates a limitation in tail-powered locomotion, and (2) the presence of powerful hip extensors and femoral adductors indicates that
Remingtonocetus was an efficient and specialized foot-powered swimmer.
Remingtonocetus had four working and usable limbs, a slender
whale-like body with long tail and slender,
hydrodynamic head. ==Taxonomy==
