((In honor of October, Seishinās skull! Fancy-shmancy biological musing below the cut!))
Note: I have no idea if this would actually work as a skull, itās simply what looks decently believable to me.
One of Seishinās most prominent features is her four-jawed mouth. Analysis of her skull reveals that this is accomplished through relatively simple modifications of a ānormalā two-part jaw. The lower jaw is disconnected, as is common in many more common vertebrates, with a hinge halfway along each mandible. The upper jaw splits just anterior to the braincase and approximately inĀ line with the more forward pair of orbits.Ā
Each mandible holds a single dentary, which is somewhat reduced in the lower jaw toĀ accommodate the beak. In all four mandibles,Ā Ā the metallic beak covers the distal end, though on the upper mandibles teeth encroach on the area covered.
The skull is topped with the core to the crescent crest, which has a keratinous coating in life.
