Spinosaurus

Spinosaurus ruled the kingdom between worlds. Its massive sail — taller than

a man, supported by spines of elongated bone — rose above the riverbanks like

a warning flag, visible from a distance that gave nothing time to escape. It

hunted in water with the patience of a crocodile and on land with the reach

of something that had no business being so large and so fast at the same

time. Its claws hooked fish from the current. Its jaws crushed bone on the

shore. It moved between river and forest as if the boundary between them did

not exist, claiming both domains with equal authority. The other great

predators of the Dominion were specialists — built for the plains, or the

forests, or the hunt. Spinosaurus refused to specialize. It took everything.

The rivers, the banks, the shallows, the deep water. No creature in the

Dominion had a wider kingdom, and no creature defended it with more

relentless patience.
