George (2012) also identified several synapomorphic characters of the dentary bone
for the tribe Notiosoricini.
The mental foramen is present in the dentary bone
below the anterior portion of m1.
On the basis of detailed comparisons with living species of the genus Oligosarcus, the fossil material is well nested within the species that show a large number of teeth in the second series of the dentary bone
0] Not directly inserted on anteromesial surface of dentary bone
The changes ill the anatomy of the jaws that took place as mammal-like reptiles evolved into mammals were characterized by an increase in the size of the temporalis muscle and the dentary bone
and a reduction in the size of the postdentary bones (i.
1), together with the dentary bone
, coronomeckelian and Meckel's cartilage, constitute the mandible.
Lastly, the Aw, which is well-developed, attaches anteriorly on the mesial surface of both the dentary bone
and the angulo-articular and posteriorly on the tendon of the A2.
Mandibular length (MDL): The length of the lower jaw, from the top of the dentary bone
to the caudal most projection of the angle.
These are the maxillary, premaxillary and dentary bones
In the two males, teeth on the rostromedial vomerine tooth ridges appeared more hypertrophied than either teeth on the caudolateral vomerine ridges or on the maxillary, premaxillary, and dentary bones
[ILLUSTRATION FOR FIGURE 3A, B OMITTED].
The top group represents pairs in which the premaxilla, maxilla, and dentary bones
are advanced; the second group represents characters in which other bones are advanced; the third group represents characters in which other skeletal structures are advanced; and the final group represents those characters in which muscles are advanced.
in association with the rostrum, a small fragment of one of the dentary bones
with one or more cheek teeth is accreted onto the palate and is mostly covered in matrix, obscuring the contained lower teeth as well as some maxillary teeth.
