New information on Late Triassic sauropodomorph dinosaurs provides support for the independent acquisition of postcranial skeletal pneumaticity in avemetatarsalian lineages

open access: yesJournal of Anatomy, Volume 248, Issue 3, Page 541-578, March 2026.
PSP in early‐branching sauropodomorphs probably evolved first in the neural arches of the posterior cervical vertebrae, expanding anteriorly and posteriorly along the vertebral column. The distribution of PSP in Late Triassic early‐branching sauropodomorphs does not appear to be correlated with body size.
