Article: Small Naiadites obesus from the Calciferous Sandstone Series (Lower Carboniferous) of Fife
G. M. Bennison
Small specimens of Naiadites occur at two horizons in the Calciferous Sandstone Series of Eastern Fife. At one horizon the small shells constitute an indigenous 'life-assemblage' (now a fossil community), and are described as dwarfed, whereas at the other the shells are exotic, comprising a fossil assemblage that should be termed a 'pebble necrocoenosis'. Variation is illustrated, and the affinities of these small Naiadites are re-examined. All are referred to the species N. obesus s.l.
