Primeval Spinosaurus
About
An ancient river-leviathan of a spinosaur, its sail scarred and barnacled, that rules a whole watershed and drags entire boats under without breaking stride. Nothing that drinks from its river does so twice unwatched. It has ruled its drowned kingdom for centuries, grown vast and patient, and the river-folk leave offerings at the water's edge rather than risk its notice - it takes fish, beast, boat, or war-band with the same unhurried certainty.
