Fish tooth, Jurassic; GER

Tooth of an ichthyosaur.Age: Lower Jurassic, Posidonia shaleLocality: Holzmaden, Baden-Württemberg, GermanySize of the tooth: 0,7 cm lang Slab: 6 x 4 x 2 cmWith its wonderfully preserved fossils, the Holzmaden deposit is world famous. Complete ichthyosaurs, plesiosaurs, pterosaurs and marine crocodiles lie among vast quantities of Dactylioceras ammonites. It is assumed that weak water circulation created anoxia (= complete absence of oxygen) at the bottom, so that scavengers and decomposers could not disintegrate the bodies of deceased animals.Colors on pictures may differ slightly from those of the original piece due to technical reasons.

Tooth of an ichthyosaur.Age: Lower Jurassic, Posidonia ShaleLocality: Holzmaden, GermanyTotal Size: Tooth: 8 mm; Rock: 9 x 8 x 2 cmThe lagerstätte of Holzmaden is famous for its high-degree of preservation. Every so often entire Ichtyosaurs, Plesiosaurs, Pterosaurs and Marine Crocodiles are found among literal millions of Dactylioceras ammonites. It is reckoned that a low degree of circulation caused anoxia at the bottom of the sea, which prevented scavengers from destroying the carcasses of deceased animals.Color on pictures can differ from original due to technical reasons.

Vertebra beautifully prepared on the original matrix.Period: Jurassic, Lias;Location: Mistelgau, BavariaSize: Vertebra: 4.5 x 2 cm, Matrix: 14 x 4 x 2 cmSince the beginning of the 20th century, the “Jurensis marl” of the Upper Lias and the overlying “Opalinus clay” of the Lower Dogger have been mined near Mistelgau for brick production. However, the quarry gained worldwide renown among experts due to the large number of exceptionally well-preserved fossils. Famous is the nearly one-meter-long skull fragment of a Temnodontosaurus, which is on display at the Urwelt-Museum in Bayreuth. In addition, marine crocodiles, dozens of ichthyosaurs, countless smaller fossils such as snails, as well as cephalopod-like ammonites (“silver snails”) and belemnites (“thunderbolts”), fish, mussels, and insect remains have been found. The abundance of fossils makes the Mistelgau Pit an internationally significant site for research into the evolution of these organisms.Colors in product photos may differ slightly from those of the original specimen due to technical reasons.

Stenopterygius sp.  Rib fragment on matrix with impressions of several Posidonia shells!A classic specimen from this formation.Age: Lower Jurassic, Lias, Posidonia Shale.Location: Holzmaden, Esslingen District, Baden-Württemberg, GermanySize: Matrix: 17 x 13 x 1 cm; Rib: 9 x 1 x 0.5 cmThe Holzmaden deposit is world-famous for its wonderfully preserved fossils. Complete ichthyosaurs, plesiosaurs, pterosaurs, and marine crocodiles lie among vast quantities of Dactylioceras ammonites. It is believed that weak water circulation created anoxia (a complete lack of oxygen) at the bottom, preventing scavengers and decomposers from breaking down the bodies of dead animals. Colors in product photos may differ slightly from those of the original specimen due to technical reasons.
