Picture of a Dinosaur skull — sketch of Stan the Tyrannosaurus Rex. This fossil of Stan the T. Rex is on display at the Black Hills Institute of Geological Research, where I spent a day drawing in my sketchbook in May, 2008. Stan is an amazing find. Fossilized along with his skeleton was an acid-etched Triceratops bone, bitten in half, presumably it had been in Stan's stomach when he died.
