Tarbosaurus hunting mates

A pair of male and female Tarbosaurus work to wear down an escaping Shantungosaurus. But it has tripped, sealing its fate.
Dunno why, but I really liked the idea of tyrannosaurids living and working in pairs.
Tarbosaurus ("alarming lizard -love the name-") was a slightly smaller asian cousin of the famous T-Rex. It's one of the best known tyrannosaurids.
Shantungosaurus ("Shandong lizard") was another asian simile, in this case, a relative of the American Edmontosaurus. Also, it was one of the largest hadrosaurids known to date, with a length of almost fifteen meters.
