Skeletal reconstructions of prenatal Eumetopias jubatus (Steller sea lion) using micro-CT. These specimens span three developmental stages, with MCZ: Mamm:56936 showing the most immature skeleton (a), MCZ: Mamm:56934, 56937, 56935 showing an intermediate stage (b, c, d), and MCZ: Mamm:56920, 56776 (e, f) showing the highest level of ossification. Species are shown in lateral view to the extent possible given the position of the specimens. f has been flipped horizontally. Images not to scale. The texture used in the reconstruction renders was made by Katsukagi on 3dtextures.me
