  Paenungulata - Wikipedia, the free encyclopedia
The Hyraxes in his Paenungulata ("almost ungulates") offered hints that they might be connected to the perissodactyl ungulates— horses and rhinos and kin.
The most parsimonious cladograms depicted Simpson's Paenungulata as an authentic clade and as one of the most anciently diversified among the placental mammals (Eutheria), that is, among the first group to diversify from the basal placental mammals.
The molecular evidence suggests that Paenungulata in its turn is part of Afrotheria, an ancient assemblage of mainly African mammals of great diversity.

 Paenungulata   (Site not responding. Last check: 2007-10-10)
Paenungulata is a group of remarkable mammals constituting three orders: 1.
Of the aforementioned orders hyraxes are the most basal,followed by embrithopods,sirenians and desmostylians,with elephants being the crown group.
Paenungulata is part of Afrotheria,an assemblage of mainly African mammals of great diversity.The other members of this superorder are afrosoricidans (tenrecs and golden moles),elephant shrews (Macroscelidea) and aardvarks (Tubulidentata).

Members of these two orders are called the 'true ungulates' to distinguish them from 'subungulates' (paenungulata) which include members from the Proboscidea, Sirenia, and Hyracoidea orders.
As a result of these discoveries, a new order of Cetartiodactyla has also been proposed to include the members of Artiodactyla and Cetacea, to reflect their common ancestry; however, strictly speaking, this is not necessary, as it is possible simply to recognize Cetacea as a subgroup of Artiodactyla.
The Macroscelidea and Tubulidentata have recently been united with the Paenungulata in the Pseudungulata.

Contrary to morphological claims, molecular data indicate that the order Perissodactyla (e.g., horses, rhinoceroses, and tapirs) is neither part of the superordinal taxon Paenungulata (Sirenia, Proboscidea, and Hyracoidea) nor an immediate outgroup of the paenungulates.
However, a molecular analysis of 36 protein sequences with a total concatenated length of 7885 aligned amino acids indicates that Perissodactyla is closer to Cetartiodactyla than either taxa is to Carnivora.
The relationships among Paenungulata, Primates, and the clade consisting of Perissodactyla, Carnivora, and Cetartiodactylaa could not be resolved on the basis of the available data.

 Re: Internal Testes (in afrotherians)
As for Paenungulata and Uranotheria, I believe they are synonymous or nearly so.
Since ungulates may be a polyphyletic taxon, the term paenungulata may not be very appropriate anyway.
The true hooves of artiodactyls, perissodactyls, and South American ungulate groups, are probably unrelated to the nail-hooves of uranotherians (pseudungulates), except that both are derived (probably independently) from plesiomophic mammal nails.

 Origin of Sirenians
Tethyeria appear to have evolved from primitive hoofed mammals known as condylarths, along the shores of the ancient Tethys sea.
The tethyeria, combined with Hyracoidea (hyraces) form an inclusive group called Paenungulata.
Paenungulata and Tethytheria (especially the latter) are among the least controversial mammalian orders, with strong support from morphological and molecular research.

 Systematic Biology 48(1) Abstracts
The nature and degree of support and conflict for particular groups were assessed by separate bootstrap and homogeneity tests that were followed by combined analyses of the sequence and morphological data.
Between orders, strong support (i.e., >95% bootstrap scores) was found for a paraphyletic Artiodactyla (relative to Cetacea) and a monophyletic Cetartiodactyla (Artiodactyla and Cetacea) and Paenungulata (Hyracoidea, Proboscidea, and Sirenia).
Further resolution will require the integration of more recently published data, the continued sampling of taxa and characters, and the use of more powerful methods of data analysis.

The Paenungulates form part of the basal eutherian mammalian clade, Afrotheria and comprise species from the orders Sirenia (manatee, dugong, sea cow), Proboscidea (elephant) and Hyracoidea (hyrax).
Although Paenungulata is well recognized, the relationship between the three orders is uncertain.
Previous studies have used both morphological as well as molecular data in an attempt to resolve the associations, however a consensus between the different approaches remains elusive.
