lacrimal bone

Near the frontal, the lacrimal bones are unusually wide in comparison to their length.

Two lacrimal bones form part of the medial wall of each orbit.

Unlike Allosaurus, there was no prominent crest on the lacrimal bone in front of the eye.

Different subspecies can usually be distinguished by the relative lengths and shapes of their lacrimal bones.

The lacrimal bone is relatively large.

Inside the lacrimal bones were depressions that may have held glands, such as salt glands.

The lacrimal bone of Telmasaurus has a single hole in it, as do those of other early varanoids.

Both monitors have a single hole in the lacrimal bone called the lacrimal foramen.

Notharctus tenebrosus had a lacrimal bone that was positioned at the end of the orbit but not anterior to it.

These horns were composed of extensions of the lacrimal bones, and varied in shape and size.

The lacrimal bone was not in contact with the frontal anymore, having been separated from it by the prefrontal bone.

The maxilla are partly concealed, covered by the lacrimal bone, but extend till around the hind margin of the eye.

It is formed by indentations in the inferior nasal conchae, maxilla and lacrimal bone.

A tall crest rose from the lacrimal bone in front of each eye, similar to Albertosaurus and Daspletosaurus.

These crests are though to have been formed by the nasal bones solely, unlike those of many other theropods which also incorporated the lacrimal bones.

At it is a single lacrimal canal, which opens near the suture between the frontal and lacrimal bones, like in lipotyphlans.

A less prominent crest is found in Dilong, where low, parallel ridges run along each side of the skull, supported by the nasal and lacrimal bones.

They have long broad snouts, a dental formula of 2.1.4.3, a lacrimal bone within the orbit, and, except for Notharctus, an unfused mandible.

Present on the margin of the orbit, the palatine takes the place of the lacrimal bone, which usually touches the orbit in temnospondyls.

The lacrimal bone, the smallest and most fragile bone of the face, is situated at the front part of the medial wall of the orbit.

The lateral or orbital surface of the lacrimal bone is divided by a vertical ridge, the posterior lacrimal crest, into two parts.

In Albertosaurus, Gorgosaurus and Daspletosaurus, there is a prominent horn in front of each eye on the lacrimal bone.

Low, laterally raised bony ridges were present on the dorsolateral margin of the nasal and lacrimal bones in the skull, directly above the antorbital fenestra.

The point of junction of the maxillary bone, lacrimal bone, and frontal bone is named the dacryon.

Medially it is thin, and, becoming separated from the medial palpebral ligament, attaches to the lacrimal bone at its posterior crest.
