As the mist thickens, the bulls continue to try and subdue each other with their heads firmly locked . Then the older bull disengages and retreats. One of his forehead horns is hanging down and he bleeds profusely over one eye. He fails to see the approaching predator until it's too late. Running out from the mist, a large male Tyrannosaurus sinks his long puncturing teeth ferociously into the old bull's flank, tearing slabs of flesh free.
Tyrannosaurus indulge in a ritual called 'courtship feeding'.
A male makes a kill and then uses the carcass to attract the female. Responding to the mating calls of the Tyrannosaurus , an enormous female appears out of the mist. She feeds, driving her long teeth into the flesh. But through the night they mate several times and again the following day. The northern volcano has blown its top.
