RARE LARGE CERATITES
AMMONITE ON MATRIX FROM UNCOMMON TRIASSIC ERA
Upper Muschelkalk Formation - Schoningen, Germany
PERIOD: 230 million years ago
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
- the Triassic!
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!
