Dura Den, a small ravine in Kemback parish, Fife, 2½ miles E of Cupar. It is traversed by Ceres Burn on its northerly course to the Eden, and, barely 9 furlongs in length, is famous for the wealth of fossil ganoid fish enshrined in its yellow sandstone. This yellow sandstone is one of the upper beds of the Old Red, and has a thickness here of between 300 and 400 feet. The fish are found crowded together in one. thin layer, nearly a hundred finely-preserved specimens having been counted on a single slab about 5 feet square; and they consist of two species of Holoptychius (Andersoni and Flemingii), besides Dipterus, Platygnathus, Phaneropleuron Andersoni, Glyptolœmus, Glyptopomus, and Pamphractus. See Dr J. Anderson's Dura Den, a Monograph of the Yellow Sandstone and its Remarkable Remains (Edinb. 1859).—Ord. Sur., sh. 49, 1865.
