Jurassic Park - Tyrannosaurus Rex, Novel version.

Concept art for the T-rex from the Jurassic Park novel.

The idea was not to make a scientifically accurate Tyrannosaur, but to make a genetic abomination which resembles a Tyrannosaur. To emphasize the idea of suffering and illness the creatures of the park suffer, the T-rex was added rashes, sores and his tail was chewed off.

I'd love to see a horror film/TV series based on the novel.
