Fig 11. Consensus phylogeny of Ornithomimosauria showing known state of vertebral pneumaticity from the literature and personal observations.

Bolded taxonomic names indicate taxa inspected in this study. The common theropod pattern and graphical representation of vertebral pneumaticity is derived from [13]. Colored boxes indicate strong evidence of pneumatization corresponding to the vertebra type and region. Half-filled boxes denote variable pneumatization with respect to the common theropod pattern. “A” signifies ambiguous evidence of pneumatization. “?” indicates no specimen available for the vertebra type and region.
