  1. Ludwigia

    Ludwigia murchisonae (Sowerby 1825)

    From the album: Middle Jurassic Ammonites from Southern Germany

    9cm. Murchisonae Zone, Upper Aalenian, Middle Jurassic. Found in the Wutach area. This is the index fossil for this particular zone.
  2. Ludwigia

    Graphoceras decorum (Buckman, 1904)

    From the album: Middle Jurassic Ammonites from Southern Germany

    5cm. A very fine-ribbed species from the so-called Staufensis Bank in the Murchisonae Zone in the Wutach area. Upper Aalenian, Middle Jurassic.
  3. Ludwigia

    Staufenia staufensis (Oppel,1858)

    From the album: Middle Jurassic Ammonites from Southern Germany

    9cm. This species gives its name to the Staufensis Bank, which appears in certain sections of the Bradfordensis Subzone of the Murchisonae Zone, Upper Aalenian, Middle Jurassic. It is quite common to find them in the Wutach area, but the stone is so hard and the discus-shaped ammonites so fragile, that it's difficult to extricate a well-preserved specimen without damageing it in some way. This one lost much of its shell, exposing the impressions of the sutures on the calcite core and also giving a view into the crystallized chambers of the phragmocon.
  4. Ludwigia

    Ludwigia haugi (Douvillé,1885)

    From the album: Middle Jurassic Ammonites from Southern Germany

    9cm. I found this one very early in my collecting "career" and botched the hand preparation somewhat - there are lots of scratches on it - but I've kept it all this time since it's somewhat of a rarity for these parts. Also the glimpse in the chambers is nice. Found in the Wutach Valley in the Staufensis Bank of the Upper Aalenian, Middle Jurassic.
  5. Ludwigia

    Ancolioceras opalinoides ? (Mayer 1864)

    From the album: Middle Jurassic Ammonites from Southern Germany

    11cm. Murchisonae Zone, Upper Aalenian, Middle Jurassic. Wutach Valley. This one has almost completely lost its shell revealing the calcified mold showing the suture lines of the phragmacon. These were assigned to the genus Staufenia by Rieber in 1963, but Dietze, Rieber etal have revised the genera in December 2014 to the above.
  6. From the album: Middle Jurassic Ammonites from Southern Germany

    7cm. Bradfordensis-Zone, Upper Aalenian, Middle Jurassic. Quenstedt called these layers Dogger beta. Found in the Wutach area. Another calcitized mold with a bit of shell left.
  7. Ludwigia

    Ludwigia latecostata (Althof 1940)

    From the album: Middle Jurassic Ammonites from Southern Germany

    4.5cm. From the Murchisonae Zone in the Wutach Valley. Upper Aalenian.
  8. Ludwigia

    Costileioceras sinon ? (Bayle 1878)

    From the album: Middle Jurassic Ammonites from Southern Germany

    9cm. From the Sinon Bank in the Wutach area. Murchisonae Zone, Upper Aalenian. It broke into 2 pieces as I was getting it out. Can you see where I repaired it? These were assigned to the genus Staufenia by Rieber in 1963, but Dietze, Rieber etal have revised the genera in December 2014 to the above.
  9. From the album: Middle Jurassic Ammonites from Southern Germany

    11cm. Murchisonae Zone, Upper Aalenian. Found in the Wutach area.
  10. Ludwigia

    Staufenia sehndensis (Hoffmann1913)

    From the album: Middle Jurassic Ammonites from Southern Germany

    12cm. in circumference. Another one from the Wutach. Upper Aalenian. I found this one a long time ago before I knew any better and unfortunately almost destroyed the living chamber before I realized what I was doing. Haven't found any more of this species since then though, so it's still in the collection. PS in Dec.2012. I've just changed the ID from S.discoidea to S.sehndensis. We've just discovered that this is only the second of its kind identified in the Wutach area.
  11. From the album: Middle Jurassic Ammonites from Southern Germany

    3cm. Another one from the Wutach. Upper Aalenian, Bradfordensis Zone.
  12. From the album: Middle Jurassic Ammonites from Southern Germany

    L.latecostata bottom right. The others are A.opalinoides. The size of the block is 21x20x7cm. From the Upper Aalenian, Murchisonae Zone in the Wutach area. This block now resides in Virginia.
  13. Ludwigia

    Ancolioceras opalinoides ? (Mayer 1864)

    From the album: Middle Jurassic Ammonites from Southern Germany

    9cm. The shell is weathered in such a way that the sutures are good to observe. This appears to be a form between Staufenia and Ludwigia, but it has more of the former about it than the latter. Found in the Staufensis Bank, upper Aalenian in the Wutach valley. These were assigned to the genus Staufenia by Rieber in 1963, but Dietze, Rieber etal have revised the genera in December 2014 to the above.
  14. From the album: Middle Jurassic Ammonites from Southern Germany

    7.5cm. From the Wutach Valley. Staufensis bank, Achdorf Formation, upper Aalenian.
  15. Ludwigia

    Ancolioceras opalinoides (Mayer 1864)

    From the album: Middle Jurassic Ammonites from Southern Germany

    10cm. Practically complete specimen with shell preservation. Just missing a few millimeters at the mouth aperture. murchisonae zone Late Aalenian Found in the Wutach Valley
  16. Ludwigia

    Ludwigia haugi (Douvillé 1885)

    From the album: Middle Jurassic Ammonites from Southern Germany

    9.5cm. haugi subzone murchisonae zone sinon banks Late Aalenian Achdorf Formation Found in the Wutach Valley.
  17. Ludwigia

    Staufenia sehndensis (HOFFMANN 1913)

    From the album: Middle Jurassic Ammonites from Southern Germany

    14cm. in circumference. Another one from Wutach. Upper Aalenian.
  18. Ludwigia

    Glaphyrorhynchus aalensis ?

    From the album: Vertebrates (other than fish)

    Crocodile. Back part of the lower jawbone. Found at the clay pit in Geisingen. Aalenian, Geisingen Oolith. The creature was extrapolated to be at least 7 meters long, one of the largest ever found world wide in these layers. Currently in the collection at Tuebingen for research. Update Aug.2020: I've now reassigned this to Glaphyrorhynchus aalensis with a question mark according to the most recent revisions. The above photo is of the original, the two below are of the cast.
  19. A few of my ammonites collected from the Inferior Oolite at both coastal and inland quarry sites in Dorset, UK.

    Twins

    I recently recieved a very interesting block with two ammonites of the same species to prepare on commission which I would like to show you here. They lay about 10 cm. apart one over the other, so either they were imbedded at different times or else they reached their final positions through turbulence. Staufenia staufensis is the species, one having a diameter of 18cm. and the other one of 16. They come from the Middle Jurassic bradfordensis zone of the Late Aalenian. I'll show you the progression of the preparation using 4 blocks of 4 photos each showing different perspectives of the bl

    Stabilising Dinosaur Footprint

    Hello everyone, I have a question regarding stabilising sandstone to keep it from crumbling. Last year I found and extracted a dinosaur footprint from a block on the beach at Whitby, Yorkshire UK. The footprint is of an Aalenian age therapod from approximately 170 million years ago. The print itself measures 20cm from the base to the tip of the centre claw mark. I am hoping to get the block it is in cut down into a slab in order to frame it but now that it is dry the sandstone is very loose and crumbly. I am looking for something that will add strength to the stone and prevent crumbl
