Relationships of taxa in the "preferred calibration points" are based on phylogenetic analyses that combine molecular and morphological data. Taxa in "other suggested calibration points" either vary in their position among combined analyses of molecules and morphology or have been placed based on phylogenetic analysis of morphological data only. Nodes refer to node-based definitions of these taxa. FAD: first appearance datum. See text for supporting references.
