The cast of the biggest dinosaur ever discovered stands tall and extends far beyond the area that used to be taken by the popular fossil of SUE the T. rex in the large Stanley Field Hall at the Field Museum. "The installation took three days," said Bill Simpson, head of geological collections at the museum, as two workers finished the installation by connecting the dinosaur's head to its long neck on May 25. It is so tall that its head overlooks the second-floor balcony of the museum, where visitors can easily take a selfie with it. Hansen said that five people from Museo Egidio Feruglio, the museum in Patagonia, Argentina that owns the titanosaur fossils, are in Chicago to provide assistance for the move and installation. Meanwhile, SUE the T. rex will be moved to the Field Mmuseum's permanent exhibition, The Griffin Halls of Evolving Planet.
