Araucaria mirabilis
Vendor: Fossil Soup
SKU Number: SQ8581646
Araucaria mirabilis cone from the Middle Jurassic Cerro Cuadrado Petrified Forest, Patagonia, Argentina
This specimen has been cut and polished to reveal the true beauty of the internal structure of the cone in minute detail.
This cone was acquired at the Tucson, Mineral, Gem and Fossil show in the 1990’s from Ulrich Dernbach and comes with documentation to support the purchase. After 2003 the Argentine government prevented any further export of the cones. As a result, these cones are now very sought after and will only become more rare.
A series of volcanic eruptions buried the Cerro Cuadrado forest approximately 160 million years ago at a time when the A. mirabilis conifer’s cones were at maturity.
These beautiful cones have become silicified by the process of mineralization. The water that percolated through the volcanic ash was absorbed into the cones who take on the color associated with the minerals that were prevalent in the ash.

Additional Information
Araucaria mirabilis is an extinct species of coniferous tree from Patagonia, Argentina. It belongs to the genus Araucaria.
A. mirabilis are known from large amounts of very well preserved silicified wood and cones from the Cerro Cuadrado Petrified Forest, including tree trunks that reached 100 m (330 ft) in height in life. The site was buried by a volcanic eruption during the Middle Jurassic, approximately 160 million years ago.

Eparietites impendens from the Frodingham Ironstone Formation, Obtusum Zone, Lower Jurassic, Conesby Quarry, Scunthorpe, North Lincolnshire, England.
This Large 25 cm - almost 10 inch ammonite is a beautiful example of a now very rare polished British fossil from the Lower Jurassic rocks of Northern England.
The fossil orientation that was chosen during preparation, has created a very aesthetically pleasing display piece that stands proud of the Ironstone base.
Both sides of the ammonite have been professionally exposed from the rock and then polished to a high sheen. This showcases in great detail each of the suture lines between the chambers of the ammonite. The final, larger body chamber, has been "scooped out", which really helps add to the overall appeal of this fossil.

Promicroceras planicosta calcified ammonite from the Lower Jurassic, Lower Lias, Lyme Regis, Dorset, England.
Promicroceras planicosta was a species of ammonite that existed during the Early Jurassic period. These extinct cephalopods are characterized by their evolute shells with an open umbilicus and strong, flattened ribbing. Promicroceras planicosta fossils are commonly found in Lower Lias deposits, particularly in regions like Lyme Regis, Dorset, England. Their well-preserved remains contribute to our understanding of Early Jurassic paleontology and the diversity of ammonites during that time.

A nicely preserved example of the ammonite species Dactylioceras commune from the famous Whitby locality in North Yorkshire, England. These ammonites are found as concretions in sedimentary rocks on the foreshore at low tide. The outer whorl of the ammonite is usually visible on the edge of the concretion, which has to be broken open to reveal the rest of the fossil inside.
This 180 million year old early Jurassic (Toarcian) age ammonite is slightly pyritized and fully 3 dimensional with well defined rib ornamentation. It comes with a brush for buffing the pyrite to a high sheen if desired. An acrylic stand is included.
