The Largest and the most iconic dinosaur fossil named Sue has started moving to her new home in the Chicago Field Museum.

It came to Field Museum almost 18 years ago and has been the center of attraction for millions of children and adults all around the world.

But now, Sue has to leave her favorite home and move upstairs to make room for a newer, bigger, dinosaur.

Sue is around 40 feet long, so you can imagine how big is the new dinosaur which will be available for visitors in late spring this year.

Hilary Hansen, the Field’s Exhibitions Department project manager said, “When SUE comes down at the end of the month, we will be making plans to bring in a cast of the largest dinosaur ever found.”

Sue, the largest, most complete and best-preserved Tyrannosaurus rex skeleton ever found, is named after the paleontologist who discovered her in the 1990s in South Dakota.

Hansen said that head is separated from Sue’s body, not because of weight concerns, but because it is the most studied part of the skeleton.
