  1. Ludwigia

    Leiocera lineatum (Buckman 1899)

    The shell is well preserved. It may be that the "injury" at the point where the phragmocone ends and the body chamber begins was caused by a predator.
  2. Calcite steinkern of the phragmocone with partial shell remains.
  3. The shell is preserved on this phragmocone.
  4. A complete specimen with the shell preserved on one side. The transition from phragmocone to body chamber can be seen on the mold on the reverse side where the shell no longer exists.
  5. Shell preservation over calcite steinkern. About 3/4 complete.
  6. Calcite mold. Complete specimen with a smaller one attached.
  7. Calcite mold of the phragmocone with a bit of the body chamber.
  8. The calcite mold of the phragmocone of another otherwise large ammonite. Named recently by Volker Dietze after the location where it was found. Literature: Dietze etal. 2014, Aalenian (Middle Jurassic) ammonites and stratigraphy of the Geisingen clay pit (SW Germany), Palaeodiversity 7: 61–127; Stuttgart
  9. Ludwigia

    Brasilia aff. laevigata (Geszy)

    Steinkern of the phragmocone of an otherwise very large ammonite. Synonym: Ludwigia aff. laevigata (Buckman)
  10. Calcite mold. This is only the phragmocone, so it would have been quite a large creature.
  11. Most of the shell on this specimen is intact. Phragmocone.
  12. Calcite mold. This extremely variable species was newly erected in 2014 by Dietze etal. Literature: V.Dietze etal, Aalenian (Middle Jurassic) ammonites and stratigraphy of the Geisingen clay pit (SW Germany), Palaeodiversity 7: 61–127; Stuttgart 30 December 2014.
  13. Ludwigia

    Brasilia nitens (Buckman 1904)

    Calcite mold showing the suture lines of the phragmocone.
  14. Calcite mold. Phragmocone and a small part of the body chamber.
  15. Well preserved shell on one side; up to the end of the phragmocone on the other.
  16. This specimen is pictured together with Ludwigia murchisonae. In the first photo it is to be seen on the right. Otherwise it is on the left hand side. About a half of a whorl is missing on the body chamber.
  17. Not the best specimen due to the missing section of whorl, but still the best I have.
  18. You can see how large it used to be by the remnant of the body chamber on the outer flank. This is the index fossil for the two sinon bank horizons in the murchsonae zone. Old German Chronostratigrahy: Dogger (Braunjura) beta
  19. Almost complete with the shell partially preserved. Old German Chronostraigraphy: Dogger (Braunjura) beta 1
  20. Index fossil of the bradfordensis zone. Phragmocone showing typical rib structure. The last photo shows another sample which illustrates how large these ammonites could get. The diameter is 20cm. and this is still just the phragmocone. Lithology: Geisingen-Oolith The Geisingen-Oolith is a horizon which was built and reworked over a long stretch of time at the coastal fringe of an arm of the Tethys ocean. Fauna from both the concavum and the bradfordensis zones are to be found in it. Old German Chronostratigraphy: Dogger (Braunjura) beta Literature: Dietze et al (2014
  21. This is the index fossil of the concavum zone. Most of the shell is preserved, as is a small portion of the body chamber. These ammonites could reach a good size, as shown by the sample in the last 2 photos, which has a circumference of 21cm. Lithography: Geisingen-Oolith The Geisingen-Oolith is a horizon which was built and reworked over a long stretch of time at the coastal fringe of an arm of the Tethys ocean. Fauna from both the concavum and the bradfordensis zones are to be found in it. Old German Chronostratigraphy: Dogger (Braunjura) beta Literature: Dietze et
  22. This is the index fossil of the murchisonae zone. This sample was disturbed either during burial or later tectonically at the point where the phragmocone meets the body chamber. The shell is completely preserved on one side showing clearly the typical ribbing. It is not quite complete, still missing about a half turn around the axes. Old German Chronostratigraphy: Dogger (Braunjura) beta Literature: Rieber,H. (1963): Ammoniten und Stratigraphie des Braunjura beta der Schwaebischen Alb, Palaeontographica Bd.122,Abt.A, Pp.1-89
  23. This species has long been a subject of contention as to its lineage, but Dietze (2014), following the chronospecies/genus concept, has managed to prove to the satisfaction of most that it belongs to the subfamily of the Leioceratinae. Rieber (1963) had placed it in the subfamily Staufeniinae and had named it Staufenia opalinoides, a name which most collectors and paleontologists adopted, since his work was the most comprehensive one on the ammonite fauna of the area for many years. This almost complete specimen has most of its shell intact. The band of variation of ribbing and other scul
  24. To be seen on the matrix below the ammonite are 2 Myophorella formosa bivalves on the right and a Staufenia opalinoides ammonite. The shell on one side is completely preserved. The other side shows the calcite mold with sutures on the phragmocone. Only a small section of the body chamber on this specimen is preserved. If complete, it would probably have had a diameter of approximately 16cm. This is the index fossil of the subzone. Old German Chronostratigraphy: Dogger (Braunjura) beta Literature: Rieber,H. (1963): Ammoniten und Stratigraphie des Braunjura beta der Schwaebische
