Trix (dinosaur)

Trix, Tyrannosaurus rex, in the dinosaur hall at Naturalis Biodiversity Center in Leiden, the Netherlands. The skeleton on show is the real fossil, and it is one of the most complete T. rex specimens known, with roughly 80 percent of the original skeleton preserved, which puts it in the same company as SUE and Stan. Trix is also unusually old for a T. rex, estimated at more than 30 years at death. When Naturalis needed a Trix to send abroad, it 3D-printed a copy for a museum in Japan and kept the real bones in Leiden.
