Predator, Prey, Precursor (Patreon)

This is the illustration of the regal skulossus used for reference for the river dragon hunting scene, imperious river dragon for scale (brontocorn also present for additional scale). This is the second largest skulossus species, behind only the monarch skulossus.

Quite a substantial animal, it would be a rather difficult catch for a river dragon when full-grown. Truly, it would be a battle of titanic proportions as the mega-serpent attempts to bring down a sixteen-tonne behemoth within its coils. Alas, most predators prefer to be pragmatic over being cool.
