Extract

The exact and exhaustive study of the Quaternary terraces of the Somme, which we owe to Commont, may well serve as a starting point in any consideration of this subject. In its results it is not without its surprises, for we should scarcely expect to find, as we do, that the gravels which form the earliest deposits on each of the three lower terraces all contain the remains of a “warm” fauna; the third or highest of these terraces affording Elephas meridionalis, the first and second E. antiquus and its companion Hippopotamus. Associated with these faunas are flint implements of early types. Pre-Chelléan in the third terrace, typical Chelléan in the second, and Chelléan “evolué” in the first. No signs of a cold climate are to be discovered in any of these gravels until we reach that of the first terrace, where a newer gravel is to be seen invading the older and bringing with it Acheuléan implements and the mammoth.
