| They therefore identified the medial, proximal tarsal bone of Diadectes as the intermedium and equated it with the reptilian astragalus. |
| On the distal margin of the intermedium illustrated by Williston is a very small, subrectangular nubbin-like process that could represent an incorporated proximal centrale. |
| The ulnare, intermedium and pisiform are comparatively large flattened bones, the others are small and cubical. |
| As might be expected, there is no sign of an incisure on the distolateral margin of the intermedium for the perforating artery. |
| For more than 50 years, it has been known that some lobe-finned fish have homologues of two wrist bones, the intermedium and ulnare. |
| It is thickest at its presumed proximal end and is expanded medially to form an overlapping joint with the intermedium. |
