I give you the Queen of the Dinosaurs, FMNH PR 2081, AKA Sue, the Tyrannosaurus rex.
I tried a more painterly style with this one, as opposed to the comic/animated look of my other drawings.
Sue was discovered in 1990 by a woman named Sue Hendrickson. It's the most complete T. rex skeleton ever discovered, at 90% by bulk, and 73% by number of bones.
After it was discovered, Maurice Williams, a Native American man who owned the land, sued (heh) for ownership of the fossil, saying it belonged to the Sioux tribe (pronounced like 'Sue', because of course). In 1992, the FBI raided the site where the fossil was being cleaned and took it, storing it until the lawsuit was settled.
In 1996, the courts ruled in favor of Williams, who, after all that, decided to auction off the skeleton. The Field Museum in Chicago placed the winning bid of 7.6 million dollars, the highest price ever payed for a dinosaur at the time, using funding from the California State University, Disney, McDonald's, and other donors.
This image shows which bones in the display are real, the rest being replicas to fill in the gaps. Sue's real skull was deformed, having been crushed before it fossilized.
