• A disznódelfinfélék (Phocoenidae) az emlősök (Mammalia) osztályának párosujjú patások (Artiodactyla) rendjébe , ezen belül a cetek (Cetacea) alrendágába tartozó család . (wikipedia.org)
  • The emergence of Cetacea in the Paleogene represents one of the most profound macroevolutionary transitions within Mammalia. (montclair.edu)
  • In the mean time, a revaluation of their taxonomic systematics is going on, in concomitance with the discovery that the order of the Artiodactyls ( Artiodactyla ) has a common origin with that of the Cetaceans ( Cetacea ), so much that nowadays they talk of polyphyletic order of the Cetartiodactyls ( Cetartiodactyla ).

  • Artiodactyla Even-toed Ungulates Sorkkaeläimet - 190 spp. (funet.fi)
  • Here, we first place Cetacea relative to extant mammalian diversity, and assess the distribution of support among molecular datasets for relationships within Artiodactyla (even-toed ungulates, including Cetacea). (montclair.edu)
  • We then merge trees derived from three large concatenations of molecular and fossil data to yield a composite hypothesis that encompasses many critical events in the evolutionary history of Cetacea. (montclair.edu)
  • Artiodactyla" is a descriptor in the National Library of Medicine's controlled vocabulary thesaurus, MeSH (Medical Subject Headings) . (harvard.edu)

  • Close CC0 - Creative Commons Project: Development of the skull of the minke whale (Mysticeti, Cetacea) and the teeth-to-baleen transition About the project Baleen whales (Mysticeti) have an extraordinary fossil record documenting the transition from toothed raptorial taxa to modern species that instead bear baleen plates, keratinous bristles employed in filter feeding. (doglink.pt)
  • In terms of tree length, the molecule-based topology is contradicted by morphological data with and without extinct taxa, and unlike previous, morphology-based analyses, the exclusion of Cetacea from the clade of living artiodactyls is not dependent on the inclusion of extinct taxa. (amnh.org)
  • Doing this caused "a reduction in resolution" such that the grouping of Cetacea and hippopotamus disappears, leaving just the grouping of Cetacea and artiodactyls. (richardhartersworld.com)
  • Even-toed ungulate is the common name for any of the hoofed, mostly herbivorous, terrestrial mammals comprising the order Artiodactyla , characterized by a double-pulley astragalus (a bone in the ankle joint) and an even number of functional toes (two or four), with the main limb axis passing between the middle two digits. (newworldencyclopedia.org)
  • Artiodactyla is one of two living orders of ungulates (hoofed mammals), the other being Perissodactyla, the odd-toed ungulates . (newworldencyclopedia.org)
  • Some previously suggested artiodactyl synapomorphies, such as an enlarged facial exposure of the lacrimal and absence of contact between the frontal and alisphenoid, are shown to be synapomorphies of more exclusive clades within Artiodactyla. (amnh.org)
  • We reexamine relationships of critical extinct taxa that impact our understanding of the origin of Cetacea. (nih.gov)
  • We do this in the context of the largest total evidence analysis of morphological and molecular information for Artiodactyla (661 phenotypic characters and 46,587 molecular characters, coded for 33 extant and 48 extinct taxa). (nih.gov)
  • A recent MRP supertree that favoured 'outdated' hypotheses (notably, monophyly of both Artiodactyla and Lipotyphla) has been heavily criticised for including low-quality and redundant data. (biomedcentral.com)
  • This branch contains animals classified under the orders Cetacea and Artiodactyla. (wikipedia.org)
  • As evident by the names of the orders-Artiodactyla comes from the Greek artios , meaning "even numbered" or "entire" and dactylos , meaning finger or toe, and Perrissodactyla from the Greek perissos , meaning "odd" and dactylos -the two groups are primarily distinguished by the feet (Shackleton and Harestad 2004). (newworldencyclopedia.org)
  • Artiodactyla is diagnosed in all most parsimonious trees by several characters, including a short mastoid process of the petrosal, absence of an alisphenoid canal, and presence of an entocingulum on P4. (amnh.org)
  • The relationships of Mesonychia and Indohyus are highly unstable, however--in trees only two steps longer than minimum length, Mesonychia falls inside Artiodactyla and displaces Indohyus from a position close to Cetacea. (nih.gov)
