The Late Jurassic is the third epoch of the Jurassic Period, and it spans the geologic time from 161.2 ± 4.0 to 145.5 ± 4.0 million years ago (Ma), which is preserved in Upper Jurassic strata. In European lithostratigraphy, the name "Malm" indicates rocks of Late Jurassic age. In the past, this name was also used to indicate the unit of geological time, but this usage is now discouraged to make a clear distinction between lithostratigraphic and geochronologic/chronostratigraphic units.

Famous quotes containing the word late:
“No such sermons have come to us here out of England, in late years, as those of this preacher,—sermons to kings, and sermons to peasants, and sermons to all intermediate classes. It is in vain that John Bull, or any of his cousins, turns a deaf ear, and pretends not to hear them: nature will not soon be weary of repeating them. There are words less obviously true, more for the ages to hear, perhaps, but none so impossible for this age not to hear.”
—Henry David Thoreau (1817–1862)
