The most intact tyrannosaurid dinosaur fossil found to date is a subadult specimen of Gorgosaurus libratus - TMP 1991.036.500 - from Dinosaur Provincial Park in southern Alberta, Canada. The skeleton is approximately 93% complete (or 98% based on volume), missing only the left forearm, gastralia and a few toe bones. It measures 5.1 m (16 ft 9 in) in length from the premaxilla to the tip of the tail and has a complete skull. It was found fully articulated in the classic theropod “death pose” - the head and tail thrown back over the body, and limbs pulled in. The specimen is housed at the Royal Tyrrell Museum in Drumheller, Alberta, Canada, where it is on public display.
The specimen was found by a Royal Tyrrell Museum field crew (Phil Currie, Darren Tanke) while prospecting in Dinosaur Provincial Park on 30 July 1991, and collected by a crew from the Museum in the following weeks.
