Recherches sur les graines fossiles silicifiées
This 1881 French atlas, Recherches sur les graines fossiles silicifiées, was compiled by Jean-Baptiste Dumas and Adolphe Brongniart and published by the Imprimerie Nationale for palaeobotanical study of petrified seeds. Its sepia plates show magnified cross-sections of fossil seed coats, with cellular patterns in thin bands, concentric layers and stippled tissue that a designer could draw on for organic textures, cell-pattern motifs and earthy brown colour palettes.
