Century Dictionary and Cyclopedia
- In the Linnean classification, one of the primary divisions, a subclass or super-order, of Mammalia, including all the hoofed quadrupeds, the two Linnean orders Pecora and Belluæ (except the elephant and walrus, which Linnæus placed in Bruta, an order of his Unguiculata). The Ungulata were thus nearly equivalent to the orders Pachydermata, Solidungula, and Ruminantia, and correspond to the modern orders Artiodactyla (the ruminants, pigs, and hippopotamuses) and Perissodactyla (horses, tapirs, and rhinoceroses), together with the Proboscidea and Hyracoidea, and certain fossil groups, as the Ambiypoda. The term, like the correlated Unguiculata, has lapsed from a strict classificatory sense, but is still used as a convenient designation of hoofed quadrupeds collectively or indiscriminately.
GNU Webster's 1913
- n. (Zoöl.) An extensive group of mammals including all those that have hoofs. It comprises the Artiodactyla and Perissodactyla.
WordNet 3.0
- n. in former classifications a major division of Mammalia comprising all hoofed mammals; now divided into the orders Perissodactyla (odd-toed ungulates) and Artiodactyla (even-toed ungulates)
Examples
“At the same time the differentiation of artiodactyle and perissodactyle forms existed as long ago as in the period of the Eocene ungulata, and that in a marked degree, as has been before observed.”
“However, it is especially with the rodents, the ungulata, and the ruminants that we find a highly developed practice of mutual aid.”
“The mammalia, for example, were long thought to have first appeared in Tertiary times, where they are represented in some of the earlier deposits by all the great divisions of the class fully developed -- carnivora, rodents, insectivora, marsupials, and even the perissodactyle and artiodactyle divisions of the ungulata -- as clearly defined as at the present day.”
“Within the last few years this has been done fully in the case of the horse, less completely in the case of the other principal types of the ungulata and of the carnivora; and all these investigations tend to one general result, namely, that, in any given series, the successive members of that series present a gradually increasing specialisation of structure.”
“Take the mammalia, and it is in like manner found to be composed of five orders, -- the cheirotheria, {239c} ferae, cetacea, glires, ungulata.”
“The rasorial type comprehends most of the animals which become domesticated and useful to man, as, first, the fowls which give a name to the type, the ungulata, and more particularly the ruminantia, among quadrupeds, and the dog among the ferae.”
“With sanguinary, he has also gentle and domesticable dispositions, thus reflecting the characters of the ungulata, (the rasorial type of the class,) to which we perhaps see a further analogy in the use which he makes of the surface of the earth as a source of food.”
