The E-T secondary electron detector can be used in the SEM's back-scattered electron mode by either turning off the Faraday cage or by applying a negative voltage to the Faraday cage. However, better back-scattered electron images come from dedicated BSE detectors rather than from using the E–T detector as a BSE detector.
At present, two species of Tyrannosaurus are considered valid; the type species, T. rex, and the earlier in age and more recently discovered T. mcraeensis. As the archetypal theropod, Tyrannosaurus has been one of the best-known dinosaurs since the early 20th century and has been featured in film, advertising, postal stamps, and many other media.
Tyrannosauroidea (meaning 'tyrant lizard forms') is a superfamily (or clade) of coelurosaurian theropod dinosaurs that includes the family Tyrannosauridae as well as more basal relatives.
Originally, the Field Museum had plans to incorporate Sue into their preexisting dinosaur exhibit on the second floor, but had little left in their budget to do so after purchasing it. Instead, the T. rex was put on display in the building’s main hall directly in front of the museum’s north entrance, where it would remain for the next 18 years.
Two young brothers and their cousin were wandering through a fossil-rich stretch of the North Dakota badlands when they made a discovery that left them “completely speechless”: a T. rex bone ...
The eye-sockets of T. rex faced mainly forwards, giving it good binocular vision. The eye-sockets of Tyrannosaurus are positioned so that the eyes would point forward, giving them binocular vision slightly better than that of modern hawks. While predatory theropods in general had binocular vision directly in front of their skull, tyrannosaurs ...

Part of the campaign was a dinosaur sticker book action by the Dutch largest supermarket chain, Albert Heijn, centred on the new skeleton and using Wikipedia images. In September 2016 Dutch media reported that Trix's arrival in Leiden had resulted in €1.3 million of "free publicity" for the museum.
