At the time of its discovery, this specimen was the largest Tyrannosaurus rex skull yet recovered (museum collections now have larger ones). The skull, housed at the Natural History Museum of Los Angeles County, was prepared, reconstructed and cast in resin by fossil preparator Mary Jean Odano (first two photos), who also made a cast for me. My Mom is one of the photos posing with my copy after it became one of my personal collection. The last photo show the actual skull, sans reconstruction, currently on exhibit at the Los Angeles Museum.
