Desc: T. Rex Autopsy: Directed by Richard Dale. With Steve Brusatte, Jack Davenport, Luke Gamble, Victoria Herridge. National Geographic is peeling back the skin to go deep inside one of the Earth's most mysterious creatures, combining biology with palaeontology to explore all its guts and glory. T-Rex Autopsy will literally go under the skin of a full-size T-Rex for the first time ever to reveal how the 65-million-year-old beast may have lived. The massive monster will be life- like inside and out, giving scientists the chance to touch it, smell it, scan it, X-ray it and cut it open from head to toe.
