It forms a tendon which inserts onto the coronoid process of the mandible, with its insertion extending into the retromolar fossa posterior to the most distal mandibular molar. [3] In other mammals, the muscle usually spans the dorsal part of the skull all the way up to the medial line.
In human anatomy, the mandible's coronoid process (from Greek korōnē 'hooked') is a thin, triangular eminence, which is flattened from side to side and varies in shape and size. Its anterior border is convex and is continuous below with the anterior border of the ramus .
The coronoid process is a thin, triangular eminence, which is flattened from side to side and varies in shape and size. The condyloid process is thicker than the coronoid, and consists of two portions: the mandibular condyle, and the constricted portion which supports it, the neck. The condyle is the most superior part of the mandible and is ...
In anatomy, the zygomatic arch, or cheek bone, is a part of the skull formed by the zygomatic process of the temporal bone (a bone extending forward from the side of the skull, over the opening of the ear) and the temporal process of the zygomatic bone (the side of the cheekbone), the two being united by an oblique suture (the zygomaticotemporal suture); [1] the tendon of the temporal muscle ...
The masseter (composed of the superficial and deep head) The temporalis (the sphenomandibularis is considered a part of the temporalis by some sources, and a distinct muscle by others) The medial pterygoid; The lateral pterygoid; In humans, the mandible, or lower jaw, is connected to the temporal bone of the skull via the temporomandibular ...
The coronoid head of the masseter's tendon and muscle fibers run posterolaterally from the coronoid process of the mandible towards the posterior third of the zygomatic arch. Its function is believed to be the retraction of the mandible and the stabilization of the mandibular coronoid process. [6] [7]

The teeth are largest right behind the tip of the snout and diminish in size towards the back of the mouth. The complete left mandible was 2.6 centimeters (1.0 inches) in length, indicating that the skull was similar in size. The mandible would have preserved approximately nineteen teeth, further back it rises up into a pronounced coronoid process.
