Excerpt: The diagram on the preceding page represents the subdivisions of the Great oolite, arranged in their order of parallelism and of superposition, as they occur over the region of the Cotteswolds. These several masses present distinctive petrographie features, which are of importance both to the Geologist and the Agriculturist. The zoological features of these several subdivisions, however, have a much greater affinity for each other than the stages of the Inferior oolite have been shewn to possess, so that a series of testacea, procured from any one of the subdivisions, will be found to be separated from the others by distinctions of very subordinate value, and to contain only those few additional forms of animal life which any distinct bed of the same stage may be expected to possess. From the foregoing conditions, both mineral and zoological, it may be inferred that these several subdivisions are really of less stratigraphical importance than the amount of their masses alone might lead us to suppose, that they represent only the varying local conditions of the bed of the Great oolite sea, and that the variations of the marine fauna which they disclose are to be attributed to the varying mineral character of the beds, to the depth of the sea, to the action of currents, to sub-estuarine deposits, and to all or either of those causes of local change, which a s...« less
