PremaxillaPosteriorPalatineBonePartialJawsOntogeneticUpperCompleteRare
Premaxilla4
  • Each premaxilla has four teeth set into it. (wikipedia.org)
  • Enlarged teeth on premaxilla, dentary and palatine. (nct4g.org)
  • Premaxilla narrow, widest point of premaxillary body 12-14 % in premaxillary length. (nct4g.org)
  • Data from these scans provide new anatomical information, such as the presence of branching vascular canals within the premaxilla and dentary, and an undescribed dorsal (quadrate) wing of the pterygoid hidden within matrix. (peerj.com)
Posterior1
  • The new species belongs to the subgenus Bryconops based on its edentulous and short maxilla, with the posterior extension of that bone not reaching the junction between the second and third infraorbitals. (bio.br)
Palatine1
  • The palatine bone in the roof of the mouth connects to the maxilla bone of the snout by a region of bone called the cuneiform process. (wikipedia.org)
Bone1
  • The dentary bone of the lower jaw has ten teeth on either side, with two diastemata separating them. (wikipedia.org)
Partial2
  • C. paulistanus is known only from the holotype specimen MPMA 67-0001/00, an almost complete and undeformed skull and mandible with teeth (only three teeth are missing) and partial postcranium from a single individual. (wikipedia.org)
  • In this paper, we describe the partial skeleton of a large ichthyosaur from the Lower Jurassic (lower Sinemurian) of Warwickshire, England, which was conserved and rearticulated to form the centrepiece of a new permanent gallery at the Thinktank, Birmingham Science Museum in 2015. (peerj.com)
Jaws4
  • 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)
  • Protoceratops , like many other ceratopsians, were herbivores equipped with prominent jaws and teeth suited for chopping foliage and other plant material. (wikipedia.org)
  • 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)
Ontogenetic2
  • 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)
  • 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)
Upper1
  • P. andrewsi had a pair of cylindrical, blunt teeth near the tip of the upper jaw. (wikipedia.org)
Complete1
  • Complete plesiosaur skeletons are relatively abundant in the Lower Jurassic of England and Germany, but are exceptional in France. (bioone.org)
Rare1
  • The stratigraphic provenance of this specimen merits particular attention, because plesiosaurians of Pliensbachian age are rare compared to other stages of the Lower Jurassic. (bioone.org)
