Sue the Tyrannosaurus Rex discovered in South Dakota in 1990 was 40 feet long and one of the largest predatory dinosaurs. But a century ago, paleontologists found fossils of an even bigger dinosaur on the edge of the Sahara Desert, the Spinosaurus. The fossils were completely destroyed in a World War Two allied bombing raid, leaving the dinosaur something of a mystery and not as familiar as the T. Rex.

Before miners and tourists came to western South Dakota, paleontologists were in the area digging up fossil remains of vanished creatures. In 1843 part of an ancient mammal's fossilized jawbone was found in the Badlands and the published paper on the find first started attracting the interest of paleontologists to the area.

In the summer of 1990, paleontologist Peter Larson and his team from the Black Hills Institute in Hill City unearthed a Tyrannosaurus Rex skeleton in western South Dakota near Faith. It was the largest, most complete T-Rex ever found. They nicknamed the dinosaur Sue, after Sue Hendrickson who first discovered the bones.

On August 12, 1990, in the badlands of South Dakota, paleontologist Peter Larson and his team from the Black Hills Institute unearthed the largest, most complete Tyrannosaurus rex ever found.  It was the find of a lifetime.  They named the dinosaur Sue.  Two years later, when the FBI and the National Guard showed up, battle lines were drawn over the ownership of Sue.  The U.S.

One of the most exciting dinosaur discoveries in recent years may not make it to a museum. The find of two dinosaur fossils "locked in mortal combat" will instead hit the auction block in New York, and the set is expected to bring in a $7 to $9 million haul - which would make it one of the most expensive dinosaur fossils ever. Dubbed the "Montana Dueling Dinosaurs," the fossils were found in 2006 by commercial prospectors on private land. According to The New York Times, dinosaur fossils discovered on private property in the U.S.
