Figure 5 in Osteology and phylogenetic position of the diminutive 'microsaur' Odonterpeton triangulare from the Pennsylvanian of Linton, Ohio, and major features of recumbirostran phylogeny

Figure 5. Patterns of enlarged cranial foramina observed on three recumbirostran groups. A, dorsal view of a generalized molgophid skull (Brachydectes neaeberryi; modified from Pardo & Anderson, 2016), showing the patterns and distribution of enlarged foramina observed across Molgophidae. B, dorsal view of a generalized brachystelechid skull (Carrolla craddocki; modified from Huttenlocker et al., 2013), showing the patterns and distribution of enlarged foramina observed across Brachystelechidae. C, dorsal view of a generalized odonterpetid skull (Odonterpeton triangulare), showing the patterns and distribution of enlarged foramina observed across Odonterpetidae.
