The Daohugou Beds are a series of fossil-bearing rock deposits located in northeastern China, with the type locality around Daohugou village of Ningcheng County south of Chifeng, Inner Mongolia, but extending into southwest Liaoning. The rocks are grey, finely bedded, lacustrine, sandy mudstones mixed with tuffaceous mudstones formed from the intermittent ashfall of volcanic events. The beds probably date from between the late Middle Jurassic (168 million years ago) and early Late Jurassic Period (164-152 million years ago).

Famous quotes containing the word beds:
“Nature in darkness groans
And men are bound to sullen contemplation in the night:
Restless they turn on beds of sorrow; in their inmost brain
Feeling the crushing wheels, they rise, they write the bitter words
Of stern philosophy & knead the bread of knowledge with tears & groans.”
—William Blake (1757–1827)
