Voorbeelden van trabeculae

• The widths of individual trabeculae are variable, but none is greater than 1.0 mm.

• We assume that the curvature of the trabeculae indicates the cranial direction; no exceptions to this have been reported for pterosaurian head crests.

• The maximum preserved height of the exposed trabeculae is 15 mm, and there are between 12 and 14 trabeculae per 10 mm.

• The striae most likely consist of linear trabeculae that support the crest internally.

• The linear trabeculae of the crest are slightly curved.

• New preparation of this material shows that structures previously interpreted as fine, elongate teeth of a mandible are in fact vertical linear trabeculae of a medial cranial crest.

• When the trabeculae experience stress leading to microfractures and collapse, the crescent sign appears.

• Osteosclerosis occurs at a margin where new bone is placed over dead trabeculae.
