		The extinct suborder Archaeoceti is a wastebasket group that includes all ancient toothed Cetacea that lack the cranial features of Odontoceti and Mysticeti.
		It is comprised of three extinct families: Protocetidae, Remingtonocetidae, and Basilosauridae.
		The family Basilosauridae is comprised of two extinct subfamilies: Dorudontinae and Basilosaurinae.

		They probably lived most of their time in the water, but were still able to go ashore if necessary.
		The families Basilosauridae and Dorudontidae had their greatest diversity around 35 million years ago.
		The animals were similar to modern whales, with a slender body, short neck and strongly reduced fore- and hind limbs.

		The abrupt change in shape and thickness noted by Uhen is quite clear, and this indeed suggests the presence of some novel caudal structure.
		However, the "ball vertebra" described by [T+01] as a synapomorphy of Basilosauridae is simply not present, nor is there a caudal peduncle.
		So, this is not a fluke such as a whale might have today.

	Creationist Mindblocks to Whale Evolution
		And yes, Basilosaurus is not considered to have been ancestral to modern whales, however, in quoting Stahl, Sherwin wrongly lumps "[i.e., Basilosaurus and related creatures]" with "these archaeocetes".
		There are two families (or arguably, subfamilies) of later archaeocetes; the Basilosauridae and the Dorudontidae.
		The dorudontids possessed bodies typical of later whales, and very little of their postcranial skeletons differs much from later odontocetes and mysticetes.

		The stages of early whale evolution that we have documented are shown here in Figure 1.
		We have found and collected virtually complete skeletons of middle-to-late Eocene Basilosauridae (Dorudon and Basilosaurus), exceptionally complete skeletons of middle Eocene Protocetidae (especially Rodhocetus and Artiocetus), and a partial skull of earliest middle Eocene Pakicetidae (Pakicetus).
		Recovery of diagnostic ankle bones in the skeletons of primitive protocetids during our field work in Pakistan in 2000 confirmed their derivation from Artiodactyla (the mammalian order including cows, deer, hippos, etc.), and showed convincingly that whales did not originate from mesonychid condylarths as Van Valen hypothesized (and we had expected).

		The method he used was "stratocladistics", defined as a method that "uses morphologic data in the same way that cladistic analysis does, but it allows the relative stratigraphic occurrence of the fossil taxa to be included as data in the analysis."
		Result: Basilosauridae is derived from the paraphyletic Protocetidae.
		The subfamily Basilosaurinae is derived from within the Dorudontinae, as is the Odontoceti + Mysticeti.

		Die Tiere der Familie Basilosauridae lebten zur selben Zeit wie Dorudontidae und hatten eine schlangenähnliche Gestalt.
		Sie besaßen eine Fluke und vollständige hintere Gliedmaßen, die aber wie bei Dorudontidae ebenfalls sehr klein waren.

		It has recently become clear that archaeocetes rapidly diversified during the Eocene, and at least five now-extinct families are recognized.
		One subfamily of the Basilosauridae, the Dorudontinae, is thought to have given rise to both living suborders of cetaceans (baleen whales and toothed whales) sometime during the Late Oligocene Epoch, about 25 million years ago.
		The first baleen whales had wide, flat skulls bordered by a reduced number of teeth in the archaeocete pattern.

		Dear David, You asked: When did the blow hole first appear in the fossil record, and what was the name of the animal it appeared in?
		Archaeocetes (elongated aquatic mammals comprising two families - Protocetidae and Basilosauridae) evolved from the terrestrial order Condylartha at the end of the Paleocene and then, about 50 million years ago (Early to Mid Eocene), colonised the sea.
		At this time they had nostrils located on top of their snout.

		This specimen was recovered from the late Eocene Yazoo Clay of the Cynthia Clay Pit, Hinds County, Mississippi.
		Taxonomy of this and other species is clarified and their phylogenetic position within the Basilosauridae are identified.
		This new specimen is compared to other basilosaurids, particularly Basilosaurus cetoides and Pontogeneus priscus (brachyspondylus).

		We found two most parsimonious trees, in the first tree ChM PV6950 is the sister-group to the clade including Babiacetus, Basilosaurus, Dorudon, and Eocetus.
		Characters that support its exclusion from Basilosauridae are absence of accessory cusps on posterior premolars and the vertical orientation of the supraoccipital above the foramen magnum.
		The second tree indicates a sister-group relationship with Protocetus atavus, both taxa lack nuchal tubercles.

		And now describing different portions of the fossil record regarding early whales:
		Late Eocene Archaeoceti of the family Basilosauridae (especially Dorudontinae; Uhen 1996) resemble later mysticetes and odontocetes in having a hydrodynamically streamlined body form with forelimbs modified into flippers and locomotion powered by a heavily-muscled fluked tail, while retaining reduced but functional hind limbs (Gingerich et al.
		Basilosaurids have dense tympanic bullae, pterygoid sinuses, partially isolated periotics, and large mandibular canals with lateral acoustic fenestrae, which would have enabled them to hear directionally in water.
