The Middle Jurassic is the second epoch of the Jurassic Period. It lasted from 176-161 million years ago. In European lithostratigraphy, rocks of this Middle Jurassic age are called the Dogger. This name in the past was also used to indicate the Middle Jurassic epoch itself, but is discouraged by the IUGS, to distinguish between rock units and units of geological time.

Famous quotes containing the word middle:
“The worst and best are both inclined
To snap like vixens at the truth.
But, O, beware the middle mind
That purrs and never shows a tooth!”
—Elinor Wylie (1885–1928)
