Further excavation recovered most of the holotype's skeleton—most notably the hip, sacrum, and most of ribcage and thoracolumbar series (the spine excluding the neck, sacrum, and tail). These left the holotype about 80% complete by 2002, making it the most completely known cetacean from the time period. [5]
Remingtonocetus domandaensis was named by Gingerich et al. 2001 based on a partial skeleton found in a Lutetian coastal shale in the Domanda Formation of Pakistan. [3] Remingtonocetus is larger, has a broader rostrum, and longer premolars than Andrewsiphius. It is smaller than, has more gracile premolars and molars than Dalanistes.
Remingtonocetidae was established by Kumar & Sahni 1986.It was considered monophyletic by Uhen 2010.It was assigned to Odontoceti by Benton 1993; to Remingtonocetoidea by Mitchell 1989 and Rice 1998; to Archaeoceti by Bianucci & Landini 2007; to Archaeoceti by Kumar & Sahni 1986, Fordyce & Barnes 1994, Fordyce, Barnes & Miyazaki 1995, McKenna & Bell 1997, Fordyce & Muizon 2001, Gingerich et al ...
Ambulocetidae is a family of early cetaceans from Pakistan.The genus Ambulocetus, after which the family is named, is by far the most complete and well-known ambulocetid genus due to the excavation of an 80% complete specimen of Ambulocetus natans. [2]
Kutchicetus is smaller than other remingtonocetids, and probably is the smallest Eocene cetacean. With its extremely narrow snout, it resembles Remingtonocetus and Dalanistes, but its strong tail distinguishes it from both Remingtonocetus and Andrewsiphius. Its limbs were short.

Species of the infraorder Cetacea A phylogenetic tree showing the relationships among cetacean families. [1]The evolution of cetaceans is thought to have begun in the Indian subcontinent from even-toed ungulates (Artiodactyla) 50 million years ago (mya) and to have proceeded over a period of at least 15 million years.

Zygorhiza, mounted skeleton. Basilosaurids ranged in size from 4 to 16 m (13 to 52 ft) and were fairly similar to modern cetaceans in overall body form and function. [ 7 ] Some genera tend to show signs of convergent evolution with mosasaurs by having long serpentine body shape, which suggests that this body plan seems to have been rather ...
