The dearth of analyses focusing simultaneously on morphology and molecular data is troubling because morphological data are the only characters available for much of the Tree of Life, and their use is indispensable (Wiens, 2005, 2009).
Some authors hold the opinion that morphological data are problematic in reconstructing phylogenetic trees because morphology is frequently convergent and therefore often misleading [ 37, 38].
Diploclinium until further molecular or morphological data are known.
The available morphological data are in fact contradictory regarding the relationships of Zhuchengceratops, Udanoceratops, and Leptoceratops.
Fifteen DSGCs were recorded from eleven TTX treated retinas (Fig. 3) and detailed physiological and morphological data are shown in Figure 6 (A G).
