Barnum Brown found a bed of tyrannosaur bones above the Red Deer River in 1910, took what he could carry in two weeks, and the place was lost again for most of a century. Phil Currie relocated it in 1996 from four photographs in Brown’s own records, and the Royal Tyrrell Museum has worked it since 1997. Somewhere between 12 and 26 Albertosaurus are in it, aged from two years old to twenty-eight, which is the best evidence anywhere that these animals lived in groups and died together, probably in one bad event. The park itself is a plateau standing 200 metres above the river with an old buffalo jump on it. LOOK ONLY, and the road in is steep gravel. Alberta owns every fossil in the ground here.
