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. The pattern of trabecula and pouches also creates areas where there may be local areas of stasis. Loading plays an important role in the maintenance of cancellous connectivity (through the remodelling process), and in the orientation of the trabeculae and the periosteal apposition (through the modelling process). During development, their anterior ends fuse and form the "trabecula communis". From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license.
