  • Lapworth, Charles (1879). "On the tripartite classification of the Lower Palaeozoic rocks". Geological Magazine. 2nd series. 6 (1): 1–15. Bibcode:1879GeoM....6....1L. doi:10.1017/s0016756800156560. S2CID 129165105. From pp. 13–14: "North Wales itself – at all events the whole of the great Bala district where Sedgwick first worked out the physical succession among the rocks of the intermediate or so-called Upper Cambrian or Lower Silurian system; and in all probability much of the Shelve and the Caradoc area, whence Murchison first published its distinctive fossils – lay within the territory of the Ordovices; … Here, then, have we the hint for the appropriate title for the central system of the Lower Palaeozoics. It should be called the Ordovician System, after this old British tribe."

    • The Gotlandian system was proposed in 1893 by the French geologist Albert Auguste Cochon de Lapparent (1839–1908): Lapparent, A. de (1893). Traité de Géologie (in French). Vol. 2 (3rd ed.). Paris, France: F. Savy. p. 748. From p. 748: "D'accord avec ces divisions, on distingue communément dans le silurien trois étages: l'étage inférieur ou cambrien (1); l'étage moyen ou ordovicien (2); l'étage supérieur ou gothlandien (3)." (In agreement with these divisions, one generally distinguishes, within the Silurian, three stages: the lower stage or Cambrian [1]; the middle stage or Ordovician [2]; the upper stage or Gotlandian [3].)
