In Siberia, mammoth fossils were seen as the remains of giant mole-like creatures that lived and moved underground. These subterannean monsters tore up riverbanks as they tunneled, but died in broad daylight.
In China, numerous sources, including the treatise Ly-Ki, tell of the Yin Shu, the “Hidden Rodent” or “Hidden Mouse” that dwells in dark caves. The yin shu grows from the size of a buffalo to as big as an elephant in Manchurian manuscripts, but otherwise looks mouselike. It has a no tail (or a short tail), is dark in color, and has short legs, a short neck, and small eyes. Yin shu are dim-witted, slow, and extremely powerful, digging out caves in areas with the roots of the fu-kia plant. They have shown up when rivers flooded plains, and die instantly when exposed to sunlight.
Until recently, mammoth bones in drugstores were labeled as yin shu.
