- Origin: Drügendorf, Franconia, Bavaria, Germany
- Size: H83cm W62cm D25cm
- Description: From the upper Jurassic period. Orthosphinctes sp. | Malm gamma 1
- This fascinating example dates from the 1980s and comes from a quarry that is no longer active. It has the appearance of a mosaic and is completely original and not reconstructed. With its dense, natural arrangement of ammonites, this impressive mass extinction slab contains ammonites of various sizes, with the largest measuring 21 cm in diameter. Unusually, it also shows numerous belemnites, with the longest belemnite measuring 9 cm in length. The fossil belemnites were replaced with aragonite in place of the limestone of the rest of the fossil, and were then prepared and polished to reveal their warm brown colors. The specimen measures 50 x 57 x 10 cm and is offered with a custom-made stand.
- Additional Information: Ammonites were predatory molluscs resembling a squid with a snail shell. These cephalopods had eyes, tentacles, and spiral-shaped shells. They are more closely related to a live octopus, although the shells resemble that of a nautilus. True ammonites appeared in the fossil record about 240 million years ago. The last lines disappeared 65 million years ago at the end of the Cretaceous.
