• Mahajangasuchus was a medium to large sized crocodylomorph, characterized by a strongly arched jugal, depressions beneath the orbit, a broad platyrostral snout, a massive choanal septum, a broad and rounded anterior edge of the dentary, ziphodont teeth and short mandibular symphysis, reaching posteriorly only to the posterior margin of the 2nd alveolous, superficially resembling the Cenozoic caiman Mourasuchus. (wikipedia.org)

  • Genus Induszalim name is after Indus River of Pakistan and Zalim (Urdu and Saraiki word) meaning cruel, and species named Induszalim bala is after Saraiki word bala meaning big terrible animal. (scirp.org)
  • Induszalimidae is based on Induszalim bala genus and species. (scirp.org)
  • Osteoderms and isolated teeth have also been found in association with the skeletal remains. (wikipedia.org)
  • In other groups, like non-varanid squamates such as iguanas (Edmund, 1969), the number of teeth at the rear of dental rows increased while skull growth (Brown et al. (researchgate.net)
  • The analysis of the skull of this species was carried out using three-dimensional geometric morphometrics (3D-GMM), a technique that allows comparative analysis, through robust statistical methods, of shape and its variations, using Cartesian coordinate data from a configuration of homologous landmarks.

  • Here, we present a new sphenodontian species from the Early Jurassic of North America (Arizona, USA) represented by a nearly complete articulated skeleton and dozens of upper and lower jaws forming the most complete ontogenetic series in the sphenodontian fossil record. (nature.com)
  • A considerable portion of sphenodontian fossil diversity is represented only by fragmentary specimens of little systematic value, such as isolated jaws and teeth-e.g., refs. (nature.com)
  • 1970) suggested that the addition of larger teeth at the rear of the dental rows in monophyodont lizards would be a way to maintain appropriate sized teeth in continuously growing jaws. (researchgate.net)
  • Most reptiles exhibit minimal change in tooth position and tooth count, with a few documented exceptions (e.g. (researchgate.net)
  • Leposternon microcephalum is a species belonging to the Amphisbaenia, a group of burrowing reptiles. (bvsalud.org)
  • There is a notable diastema located between the 4th and 5th maxillary alveoli, most likely to make space for a large dentary tooth. (wikipedia.org)
  • The ontogenetic reduction in tooth count in Opisthodontosaurus is difficult to quantify statistically because most of the dentaries are incomplete, making jaw length an ineffective metric by which to approximate size or age of the individual. (researchgate.net)
  • The maxilla of Mahajangasuchus are very low in lateral view, appearing almost flat, and are heavily sculpted. (wikipedia.org)
  • The deeply inset ventral margin in the maxilla suggests fleshy cheeks may have been present. (wikipedia.org)
  • Among the species of Leposternon present in South America, L. microcephalum has the widest distribution, being found in all Brazilian biomes and neighboring countries such as Bolivia, Argentina, Paraguay, and Uruguay. (bvsalud.org)
  • Reptilian dentitions tend to be homodont (Montanucci, 1968) readily masking any external anatomical evidence of a change in tooth position that would be associated with tooth replacement, as the new tooth would look very similar in size and shape to its predecessor. (researchgate.net)

  • The premaxilla possesses 1 to 4, potentially 5, tooth positions on each side, with the 3rd premaxillary tooth being the largest. (wikipedia.org)
  • Our analysis of 32 specimens has shown a pattern of ontogenetic tooth loss through the reduction of overall tooth counts from 13 to 10 tooth positions (Fig. 1I). (researchgate.net)

  • Row 4, referred dorsal vertebra MSM-64-15 in 2 views, dentary MSM-63-4 in 4 view and proximal humerus in one view. (scirp.org)
  • However, the majority of their fossils are highly fragmentary, especially within sphenodontines-the group including its single surviving species, Sphenodon punctatus (the tuatara of New Zealand)-thus severely hampering our understanding on the origins of the tuatara. (nature.com)
  • Interestingly, sphenodontians sustained a higher taxonomic diversity compared to squamates during the Triassic and Jurassic, being surpassed by the latter as the most species-rich group of lepidosaur only in the Cretaceous 4 . (nature.com)
  • 120 species of living didelphid opossums (which collectively comprise the didelphimorphian crown-clade), a diverse range of dentally plesimorphic metatherians from the Mesozoic and Cenozoic of the northern and southern hemispheres, including both crown- and stem-marsupials, have been referred to this group at one time or another (see Beck in press for a recent review).
