• snout
  • Previously proposed synapomorphies for the genus Gelanoglanis of the catfish family Auchenipteridae are evaluated and four additional features involving the relationship between the mesethmoid and premaxilla, the very fleshy anterior portion of the snout, the lack of ossification of the second through fourth infraorbitals, and the incomplete poring of the lateral line are hypothesized as synapomorphic for the members of the genus. (scielo.br)
  • Along the side of the snout are two undulations, a smaller one on the premaxilla and a larger and broader one on the maxilla. (wikipedia.org)
  • lacrimal
  • Traits distinguishing this new specimen from other wukongopterid pterosaurs include a premaxilla with a low ossified anterodorsal crest, a nasal bearing the most elongated process known in the Wukongopteridae, and a lacrimal that has a foramen in its middle portion. (peerj.com)
  • jaws
  • Evident on SAM 5882, 6046, and 6536 was a clear line of separation between the tooth and surrounding bone indicating that the teeth are implanted in the jaw, which went against the previous idea that the Mesosuchus marginal teeth were ankylosed to the jaws. (wikipedia.org)
  • characters
  • In contrast, although two iguanodontians known from the Lower Cretaceous of Thailand, Siamodon (maxilla and referred braincase) and Ratchasimasaurus (dentary), none of them provides enough characters to discuss their phylogenies in detail. (blogspot.com.br)
  • long
  • Using Liopleurodon, another large pliosaurid, as a guide, a specimen found in the Svalbard islands of northern Europe has been estimated to have been 15 metres (49 ft) long, 45,000 kilograms (99,000 lb) in weight and had teeth 30 centimetres (12 in) long. (wikipedia.org)
  • view
  • 2013)), 8-9 or more pairs of symphyseal teeth in dorsal view (12 pairs according to Benson et al. (wikipedia.org)
  • series
  • SAM 6046, one of the paratypes of Mesosuchus, consists of an incomplete right maxilla, an articulated series of the last ten presacrals, both sacrals, and first six caudals, partial forelimbs, left and right pelvic girdles, right hind limb, as well as element of left tarsus. (wikipedia.org)
