RARE MASSIVE INTACT JURASSIC OCEAN LIFE FOSSIL AMMONITE SLAB FROM GERMANY Holzmaden Black Shale Formation (Lias Epsilon) - Stuttgart, Germany JURASSIC PERIOD: 200 million years ago From the world-renown Black Jurassic oil-bearing shale of Holzmaden, Germany comes this MONSTROUS and exquisitely preserved mass mortality slab of gold pyrite Jurassic ammonites. All main species found in this formation are shown here on one single massive museum-grade specimen. There is a large Lytoceras, several large Harpoceras and numerous smaller Dactylioceras ammonites. The first two photos show both sides - there are fossils on BOTH sides of this giant slab. This unique showpiece fossil could be displayed in a custom-made stand whereby the slab would stand up on its edge like a room divider and show off BOTH sides of the slab. The slab is UNBROKEN and completely intact. The gold ammonites are naturally colored by their mineralization as the fossil was formed millions of years ago. This gold color is highly prized but varies in intensity. In this specimen, is unusually well-pronounced. Specimens like this are now becoming quite rare as almost all large-scale quarrying operations in the formation have ceased. It is likely, Holzmaden fossils of exceptional quality and size like this breath-taking example will appreciate in the future as demand far outstrips supply. Holzmaden is a highly unique formation, famous for producing some of the world's finest Jurassic marine life fossils. This specimen is perfect for either a collector of unusual and impressive fossil specimens or for an memorable centerpiece for interior design. Highly recommended to accent a room with one of nature's most beautiful prehistoric masterpieces as this would really set off any interior. The ammonites and slab have been chemically sealed to protect and stabilize the pyrite feature. NO RESTORATION OR FABRICATION. Some of the largest dinosaurs that ever walked the earth were in existence when this Lytoceras ammonite swam in the ancient seas alongside massive plesiosaurs and ichthyosaurs! Even if you could care less about fossils of any kind, you would be hard-pressed to not find this specimen anything less than breath-taking!
Ammonites varied greatly in size.
The largest
known
as small
as 2 cm (0.75 in) in diameter. During the Jurassic and Cretaceous
periods, ammonites evolved more streamlined shells for swimming and the
structure of the shell became stronger. Different shell shapes emerged
as well, such as snail-like or uncoiled. The shells of
ammonites
had hollow chambers separated by walls called septa. A tube called the siphuncle, connected the body with the
chambers allowing the animal to fill them with water or air, changing
its buoyancy in order to
Ammonites probably lived for one to six years, with the majority living two to four years. They fed on plankton (tiny free-floating organisms), sea lilies, and smaller orthoceras. Although many fed off the ocean floor, others may have caught plankton while floating or swimming via jet propulsion, expelling water through a funnel-like opening to propel themselves in the opposite direction. Because ammonites lived exclusively in marine environments, their presence also indicates the location of prehistoric seas. ALMOST ALL QUARRIES NOW CLOSED - THE LARGEST EXAMPLE WE HAVE EVER LISTED!!! 100% ORIGINAL UNBROKEN SLAB DISPLAYING LARGE, BEAUTIFUL GOLD NATURALLY PYRITIZED AMMONITES - CENTERPIECE FOR ANY INTERIOR! 50.5" long x 29.5" high, large ammonites at 9.5" across $4995 AMH-001 Actual Item - One Only |
