The anterior and interior surfaces of the sphenoid bone, as illustrated by H.V. Carter for Gray’s Anatomy.
This is one of my absolute favorite Gray’s Anatomy illustrations.
A leopard seal skull (Hydrurga leptonyx)
The Orca bone atlas is a fantastic resource for whale skeletal anatomy - you can view beautiful renderings of the skeleton and download 3d PDFs of all the bones that can then be rotated and viewed at any angle.
The 3d scans were done by the Idaho Virtualization Laboratory
