The interactive 3D-model of P. cornuta can be accessed by clicking onto Fig. 1 in the 3D PDF version of this article; see also additional files 1 and 2 (Adobe Reader Version 7 or higher required). Rotate model by dragging with left mouse button pressed, shift model: same action + ctrl (or change default action for left mouse button), zoom: use mouse wheel. Select or deselect (or change transparency of) components in the model tree, switch between prefab views or change surface visualization (e.g. lightning, render mode, crop etc.).
