Dietze V., Rieber H., Auer W., Franz M., Schweigert G., Chandler R.B., Rueter M., Chiarini R. (2014) Aalenian (Middle Jurassic) ammonites and stratigraphy of the Geisingen clay pit (SW Germany) // Palaeodiversity. Vol.7. P.61–127.

pdf: http://www.palaeodiversity.org/pdf....e_3.pdf

An account is given of the old clay pit at the Wartenberg Hill near Geisingen (SW Germany). A section ranging from the “Comptum” Subzone (Opalinum Zone, Lower Aalenian) to the Upper Aalenian/Lower Bajocian transition is described. Seven ammonite faunal horizons can be distinguished; four of them new for SW Germany. The Gigantea Subzone of the Bradfordensis Zone (Middle Aalenian) yields three faunal horizons. The ammonites of the family Graphoceratidae BUCKMAN, 1905 are described in detail. Two new species of Brasilia, B. geisingensis and B. decipiformis, are introduced.
