. The age of mammals in Europe, Asia and North America. Mammals, Fossil; Paleontology. 186 THE AGE OF MAMMALS (Fig. 79, 28), on the northern shore of the African continent, and of Hemp- stead (24). The Upper Ohgocene sands of Pyrimont in Savoy (Fig. 84, 4) are of fluviatile origin. The Ohgocene opens with the still-water marls and limestones of Ronzon (Fig. 79, ) in southern France, and closes with the extensive lacustrine or freshwater limestones of St. Gerand-le-Puy (Fig. 84, 2) in the Bourbonnais. Lignites or deposits of thick swamp vegetation are abundant, as at Calaf (Fig. 79, 25) and

Of this period are the fissure deposits or Bohnerze of the Jura (Swabia), Frohn- stetten (Fig. 79, 17), and other localities. The most famous fissure deposits are those of Quercy (Fig. 79,12) which, we may recall (p. 151), begin in the Upper Eocene and continue into Middle Ohgocene Fig. 79. — Lower Oligocene.
