Additional file 4: of Systemic distribution of medullary bone in the avian skeleton: ground truthing criteria for the identification of reproductive tissues in extinct Avemetatarsalia

Table S3. Comparison of the distributions of MB and pneumaticity in the stylopod of all studied specimens. The presence (â ) or absence (X) of osteological pneumatic features on the proximal epiphyses of the humerus and femur was recorded for each sampled specimen and confronted to the dataset on the presence (â ) or absence (X) of MB in these elements. Conflicting results are highlighted in red. (XLS 52 kb)
