II.—Notes on some Mollusca from South Australia, obtained near Mount Hamilton and the Peak Station

Published online by Cambridge University Press:  01 May 2009

Extract

The molluscan fossils figured on Plate XI. were transmitted to the Editor by Mr. Hy. Y. Lyell Brown, F.G.S., Government Geologist for South Australia. They are from two localities in that Colony, one near Mount Hamilton, 20 miles S.W. of Lake Eyre, but the greater part came from 40 S.W. of the Peak. There is nothing in the collection which could be quoted as absolutely decisive of their age, though we may fairly regard them as Mesozoic. The conditions of fossilization remind us of the Jurassic fossils of this country, and the general facies is not dissimilar. But these resemblances should not be taken for more than they are worth, the more so since we fail to trace absolute specific identity.
