Archetypes in trait space and in Westermann space. (A) Ammonoids in Westermann space. The red ellipses are the pyramid archetypes projected on the Westermann space, with 5% error in the archetype positions. Three of the pyramid archetypes lies near the vertices of the triangle, another archetype is near the edge because both D and S are dominant. The region near archetype 2 is severely warped (large red ellipse) because D,S and W are all relatively small. (note that archetypes 1,3 and 4 are inside the corresponding ellipses) (B) The pyramid in the W-D-S trait space, the ellipsoids are 5% errorbars around each vertex. These small ellipsoids translates to the red ellipses of subfigure A when switching to Westermann morphospace.
