Chapman's Pool is a small cove to the west of Worth Matravers on the Isle of Purbeck, in Dorset, England.
The rocks that form the cove are the upper parts of the Kimmeridge Clay, and are rich in fossils, especially bivalves and ammonites. Most of these fossils are flattened, but three-dimensional examples are preserved in the "Rotunda Nodules", including the age-marker ammonite, the coarse-ribbed Pavlovia rotunda.
Although manganese oxide nodules are seen, these are not local but from the cargo of the SSTreveal wrecked on the Kimmeridge Ledges below Hounstout on 10 January 1920.
