Additional file 2: of Systemic distribution of medullary bone in the avian skeleton: ground truthing criteria for the identification of reproductive tissues in extinct Avemetatarsalia

Table S2. Comparison of the skeletal distributions of MB and pneumaticity in different bird species. Data on the skeletal distribution of MB come from the present study and the study of Werning ([43]: appendix 2). Data on the skeletal distribution of pneumaticity have been compiled from O’Connor ([48]: table 2), and O’Connor ([51]: table 2). The presence (√) or absence (X) of MB and pneumaticity was recorded in different elements / regions of the bird skeleton. We highlighted in red skeletal elements considered as pneumatic and containing MB. (XLS 41 kb)
