The steppe bison was roughly twice the size of modern day bison. The steppe bison horns could span four feet.
Gold miners Walter and Ruth Roman and their sons discovered this carcass
in 1979 near Fairbanks, Alaska. Part of the bison was exposed as water from a
hydraulic mining hose melted the frozen muck in which it was embedded.
The bison carcass was covered with a blue chalky substance when it was
discovered and excavated. A mineral coating of white vivianite was produced
when phosphorus from the animal tissue reacted with iron in the soil
surrounding the bison. When the vivianite was exposed to air, it turned to a
brilliant blue, earning the bison the nickname Blue Babe, after Paul Bunyan's
giant blue ox.
