Spinosaurus is a dinosaur that perfectly exemplifies the changing ways we perceive dinosaurs. 

Originally thought to be a massive land predator like the Tyrannosaur. Recent investigations and discoveries reveal that it lived and hunted like a crocodile in the water. 

Taking that a step further, I brought this real life monster into the fantastical. With jutting horns, this awesome predator will terrify the rivers of any place it reaches.
