Daohugou Beds

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:

    Alice opened the door and found that it led into a small passage, not much larger than a rat hole: she knelt down and looked along the passage into the lovliest garden you ever saw. How she longed to get out of that dark hall, and wander about among those beds of bright flowers and those cool fountains, but she could not even get her head through the doorway.
    Lewis Carroll [Charles Lutwidge Dodgson] (1832–1898)
