Cast of a Tyrannosaurus rex skull (nicknamed “Harley”) from the Natural History Museum of Los Angeles County. The original skull, collected by Harley J. Garbani from the Hell Creek Formation in Montana during the 1960s, was then the largest T. rex skull yet known.
The real skull is on display at the Los Angeles museum. A cast of the skull is mounted in the museum’s “Dueling Dinosaurs” exhibit of the mounted skeletons of Tyrannosaurus rex and Triceratops prorsus; life-sized statues based on these mounts can be seen outside the museum (see souvenir postcards, below).
