Anatomical network models. Example of the network models for three archosaurian skulls: (A) Aetosaurus from Schoch (2007)63; (B) Plateosaurus from Prieto-Marquez and Norell (2011)107; (C) Gallus from Digimorph. The pair-wise articulations among the bones of skulls (left) are formalized as network models (middle) and later analyzed, for example, to identify the skull anatomical node-based modules (right). See “Materials and methods” for details.
