Not illustrated. 1886 Excerpt: ...and Ramphorhynctu) were lizards with bat-like wings and a light skeleton like that of a bird, but their jaws were furnished with sharp teeth. Stratigraphy. 1. Dorset and Somerset. Inferior Oolite Group.--The lowest beds of this group are well exposed on the coast near Burton Bradstock, where the cliff section is as follows: --Feet. Fuller's Earth (lower part) Limestones with Am. Parkinsoni, and a bed full of Ter. sphceroidalis at base. 5 Limestones with Am. Hmuphriesianus. 3 Cephalopoda Bed (Am. opalinus).. 4 Upper Lias. Sands with Am. jurensis...100 The basement zone consists of a brown marly ironshot limestone, and is called the "Cephalopoda Bed," from the abundance of Ammonite3, Belcmnites, and Nautili which it everywhere contains (see p. 318). It is here in two beds, with a clay parting and a layer at the base full of Bcleinnites. This zone is continuous throughout the district. The overlying limestones represent the upper portion of the Inferior Oolite, the lower zones (of Am. Sowerbyi and Am. Murchisonice) being absent near Burton, though represented inland near Sherborne and Bradford Abbas, and thence northward through Somerset; the thickness of the beds gradually increases till between Frome and Bath this limestone division is 60 feet thick. Near Sherborne and elsewhere it is quarried for building stone. The Fuller's Earth attains its maximum development in Dorset, being 400 feet thick. It is a marly clay, geuerallv of a greenish or yellowish grey, but sometimes blue; it contains many beds of the peculiar soft greasy kind of clay which is used for fulling purposeswhence the name); near the middle there are often beds of rubbly limestone, which are called Fuller's Earth rock. It rapidly thins northward, and in Somerset is only from 150 to 12...
