It also had a large crest on the quadrate bone on top of the skull.

It forms the jaw joint by articulating with the quadrate bone of the skull.

The articulation between the articular and quadrate bones at the jaw joint is well developed.

The quadrate bone has on its front edge a large wing-like expansion, touching the pterygoid.

There is also a straight or somewhat curved muscle scar on the medial surface of the quadrate bone.

They also have movable quadrate bones, which make it possible to move the upper jaw relative to the braincase.

I love what you did with the translucence on the teeth, and the way the quadrate bone racks the teeth forward.

The bones of the mandible and quadrate bones can also pick up ground borne vibrations.

As the skull is raised, the quadrate bone pushes forward and causes the lower jaw to protrude outward.

However, the premaxilla and quadrate bones were missing from the original African skull, which led to misinterpretation of its actual size by researchers.

The back of the skull held a deep otic notch in quadrate bone, likely holding a spiracle rather than a tympanum.

The quadrate bone is part of a skull in most tetrapods, including amphibians, sauropsids (reptiles, birds), and early synapsids.

In snakes, the quadrate bone has become elongated and very mobile, and contributes greatly to their ability to swallow very large prey items.

The reflected lamina is found on the articular bone, which connects to the quadrate bone of the skull to form the jaw joint.

The lower jaw consists of a much elongated quadrate bone, a tiny compound bone, and a relatively larger dentary bone.

In mammals, the articular bone has migrated to the middle ear to become the malleus, while the quadrate bone becomes the incus.

The holotype is an almost complete cranium with both pterygoids but lacking mandible, quadrate bones, and the palatine process of maxilla.

Their quadrate bone articulation with the lower jaw resembled that if a pelican or other birds that can open their beak widely.

Lizards and snakes share a movable quadrate bone, distinguishing them from the sphenodonts, which have a more primitive and solid diapsid skull.

Ancestrally, the malleus and the incus are derived from the articular and the quadrate bones that constituted the jaw joint of early therapsids.

They retained the reptilian joint between the quadrate bone of the skull and the auricular bone of the lower jaw, but they were reduced.

Baldwinonus trux is known from a fragment of a right maxilla or upper jaw bone, part of a quadrate bone, and several vertebrae.

The most recent order of reptiles, squamates, are recognized by having a movable quadrate bone (giving them upper-jaw movement), possessing horny scales and hemipenes.

The skull roof was flat and lacked a bony crest, and the quadrate bone that formed the articulation with the lower jaw was distinctly curved.

The theriodonts ("beast teeth") and their descendants had jaw joints in which the lower jaw's articular bone tightly gripped the skull's very small quadrate bone.
