For the ultimate in uniqueness to compliment any advanced collection of ammonites, this is the largest (and more unique!) Ceratites specimen we have ever offered. Prepared still partially embedded in its original matrix, the ammonite sits on the edge of a piece of host rock nodule with original cortex still intact. Incredible chamber detail can be seen on BOTH sides with the back side partially exposed to internal mineralized structures. This MUSEUM-GRADE display specimen offers the collector both, a unique provenance AND time period from which it once lived. This is a SUPERB example of this genus affording an educational and plainly visible view of the unique inner chambers attributed to this epoch. The ammonite has been prepared by us on its original host rock. Two small outer ridges have been restored and ammonite has been stabilized from the back side. This is a perfect addition for an ammonite collector wishing to augment their collection with a specimen from a lesser common geological period for ammonites - the Triassic!
Approximately 230 million years ago during the Triassic Period, vast areas of Germany were covered with a flat inland sea. Through the geological periods, this ancient seabed fossilized into hard, shelly limestone layers. Embedded in the Upper Muschelkalk rock, we find the Ceratites ammonites with their classic four-lobed chamber structures visible in the fossils. Additional lobes are sometimes seen in larger ceratites but this is simply a division of the umbilical lobe (closest to center). The Ceratites with its four-lobe chambers is a unique ammonite to the Triassic. This ammonite preferred warm, shallow seas of depths less than 100 meters.
No ammonite collection should be without fine examples of Triassic ammonites from the order Ceratitina (or Ceratitidae). These unique cephalopods were the first types to evolve from more primitive ammonites and show a much more complex suture line, shell shape and external features.
Dinosaurs were just beginning to emerge on our planet when this ammonite was alive!
