• This discovery of Zuniceratops bonebed has been suggested as one of the evidence for the claim that grouping behavior could be a synapomorphic trait for ceratopsians.
• Clade D was supported by two shared derived (synapomorphic) molecular characters and by seven morphological synapomorphies—the tail has a different color above and below; the parietal bone extends to the side of the skull; the incisive foramina (openings in the palate) extend back between the first molars; the posterolateral palatal pits (perforations of the palate near the third molars) are complex; the sphenopalatine vacuities (openings in the mesopterygoid fossa, the gap behind the end of the palate) are large; the pattern of the arterial circulation in the head is derived; and the posteroloph (a crest at the back) is present on the third upper molar.
• This group is recognised due to the clearly synapomorphic superciliary spines (spines above the eyes) shared by all of its members, in addition to its consistent monophyly in various phylogenetic reconstructions.
• It lacks an epitympanic sinus and a tympanic crest, auditory specializations that are considered synapomorphic of notoungulates, which suggests that these features evolved within notoungulates.
• DNA analyses suggest that although this trait is shared and is synapomorphic with birds, platypuses are still mammals and that the common ancestor of extant mammals lactated.
• Some of these are autapomorphies, while others are plesiomorphic characteristics or synapomorphic traits shared with other ornithomimids.
• The genus can be diagnosed among wingless cryptorhynchine weevils by the absence of a metanepisternum and by a synapomorphic structure of the tarsus with minute claws and a deeply incavated articulation of tarsomere 4.
• The synapomorphic traits of the family are, however, based mostly on one of the bones of the inner ear, the periotic bone, which is unknown in these genera except in Squalodon.
