HAMILTON, D. 1961. Algal growths in the Rhaetic Cotham Marble of southern England. Palaeontology, 4, 3, 324–333.
D. Hamilton The Cotham Marble horizon in the Upper Rhaetic of southern England includes the two well-known rocks, Landscape Marble and Crazy Cotham Marble. Previous hypotheses concerning the origin of Landscape Marble are listed and the widely quoted gas-bubble explanation is discussed critically. An algal origin is proposed for the Landscape Marble, and the Crazy Cotham Marble is shown to be a current-concentrated breccia. The Palaeontological Association (Free Access)
