		Although their general appearance is clearly different from the whales, the relationship can be ascertained by morphological details in the ear region which are found in all whales, but in no other mammals.
		Ambulocetidae were larger than Pakicetidae, about the size of sea lions.
		The body was shaped much like a crocodile, but the hind limbs were longer.

	A new middle Eocene protocetid whale (mammalia: cetacea: archaeoceti) and associated biota from Georgia Journal of ...
		With the proliferation in the last two decades of new early archaeocete genera (Table 3), there has also come an inevitable increase in family-group names (Gingerich and Russell, 1990; Gingerich et al., 1993).
		(1996a) recognized four "protocetoid" families, Pakicetidae, Ambulocetidae, Remingtonocetidae, and Protocetidae, with the latter subdivided into the Indocetinae and Protocetinae.
		This increase has unfortunately not resulted from thorough phylogenetic analysis, and the monophyly of only the Remingtonocetidae is reasonably well established.

		The archaic whales that lived in the Eocene (55-34 million years ago) are commonly referred to as archaeocetes.
		There are six families of archaeocetes: Pakicetidae, Ambulocetidae, Remingtonocetidae, Protocetidae,
		The Ambulocetidae retain the hind limb and it is possible to compare details of its structure with other mammals.

		That formation is also defined and named in this paper.
		Although the holotype skull of Carolinacetus is fragmentary, it includes the best preserved petrosal of any described specimen from the archaeocete families of Pakicetidae, Ambulocetidae, Remingtonocetidae, and Protocetidae.
		The phylogenetic relationships of Carolinacetus were determined by a cladistic analysis of a dataset that includes 16 cetacean taxa and 5 outgroups scored for 107 morphological characters.

		Lighted and magnified, a jawbone with four teeth belongs to an unknown species of Ambulocetidae, the most primitive marine whale family known.
		The jaw, acid-treated for weeks before it could be pried from a block of hard limestone, was found at a fossil site in Pakistan that paleontologist Hans Thewissen says “is just full of whale bones.”
