    Description
    Two specimens of fossils of glass sponges in the Ventriculites family, collected in Sussex, England.

    Plate 12 from the book The fossils of the South Downs; or illustrations of the geology of Sussex, by Gideon Algernon Mantell (London, Lupton Relfe, 1822).

    Inscribed above ‘Tab XII’. Inscribed below: ‘Mary Ann Mantell Sculpt.’

    The accompanying text states that: ‘Among the singular forms assumed by the siliceous specimens of ventriculites, none are apparently more difficult of explanation, than, the broad annular flints occasionally found in ploughed lands of the Downs and which bear a considerable resemblance to a coit; their origin is however satisfactory illustrated by the specimen fig. 1 Tab XII. In this example the ventriculite is inverted…Tab XII fig 2, exhibits the external surface of a ventriculite, attached to a block of chalk..’

    Gideon Algernon Mantell (1790-1852) surgeon and geologist was elected a Fellow of the Royal Society in 1825.
