Genus of mammals
Remingtonocetus is an extinct genus of early cetacean freshwater aquatic mammals of the family Remingtonocetidae endemic to the coastline of the ancient Tethys Ocean during the Eocene. It was named after naturalist Remington Kellogg.
History of discovery.
 named "Protocetus harudiensis" based on a partial skeleton, the type specimen found in the Lutetian shallow subtidal mudstone in the Harudi Formation, India. renamed it "Remingtononocetus harudiensis" due to morphological differences from "Protocetus".
"Remingtonocetus domandaensis" was named by based on a partial skeleton found in a Lutetian coastal shale in the Domanda Formation of Pakistan.
"Remingtonocetus" is larger, has a broader rostrum, and longer premolars than "Andrewsiphius". It is smaller than, has more gracile premolars and molars than "Dalanistes". "R. harudiensis" differs from "R. domandaensis" in molar morphology.
Description.
"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.
