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)

Intraspecific comparison of head lateral line canals of Hydrolagus. (nct4g.org)
Conical2
Mahajangasuchus is an extinct genus of crocodyliform which had blunt, conical teeth. (wikipedia.org)
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)
Specimen1
In specimen FMNH PR 2448 the lateral edges of the fenestrae are strongly everted, creating a narrow medial groove. (wikipedia.org)
View1
The maxilla of Mahajangasuchus are very low in lateral view, appearing almost flat, and are heavily sculpted. (wikipedia.org)
Nasal1
Medially to the antorbital fenestra the maxilla forms a prominent ridge that runs laterally to the maxillary nasal contact. (wikipedia.org)
Vertebrae1
Induszalim bala is the first diagnostic mesoeucrocodile from Indo-Pakistan subcontinent having rostrum articulated with dentary symphysis and associated vertebrae and limb bones and provides facility for comparison with other mesoeucrocodiles. (scirp.org)

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)
Ziphodont1
Induszalim bala shows anterodorsally directed external nares, high or deep and narrow rostrum, the ziphodont type laterally compressed teeth (symmetric to asymmetric oval to asymmetric D shaped, subcircular and heterodont in size), and thick rostral elements. (scirp.org)
Osteoderms1
Osteoderms and isolated teeth have also been found in association with the skeletal remains. (wikipedia.org)
Edges1
In specimen FMNH PR 2448 the lateral edges of the fenestrae are strongly everted, creating a narrow medial groove. (wikipedia.org)

Jaws2
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)
Positions3
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)
Acharacter combination of at least 28 dentary tooth positions in a dentary with one active crown and one replacement tooth for each position and non-parallel alveolar septa. (plazi.org)
Large1
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)
External1
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)
Left1
Row 1, holotypic rostrum MSM-155-19c in poaterior and left lateral views. (scirp.org)
Length1
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)
Replacement1
Tooth implantation has been conflated with other tooth characteristics, such as replacement, attachment, and morphology. (researchgate.net)
Position1
Most reptiles exhibit minimal change in tooth position and tooth count, with a few documented exceptions (e.g. (researchgate.net)
