Pararaucaria patagonica is a species of extinct coniferous tree from Patagonia, Argentina.
This specimen is from the Cero Cuadrado Petrified Forest, in Patagonia, Argentina. During the Middle Jurassic (approximately 160 million years ago) a volcanic eruption buried the forest. The petrified forest contains large amounts of well preserved silicified wood and cones, including tree trunks that were eleven feet in diameter and reached 330 feet in hight in life.
The cones, from this area, average between one and three inches in length and have an elliptical, ovoid, or spherical shape. The seeds of the cone, are found under each of the cone scales. Pararaucaria patagonica was probably similar to Araucaria mirabilis and shed only the seeds at maturity, but not the scales of the cone. So, the scales would open up and the seeds would drop out.
Individual cones from this area are not uncommon. Cones attached to the branch are rare. Two cones attached to the branch are very rare. Three cones attached to the branch are extremely rare. The cones, for this branch, were found with the branch and had to be reattached. The cones, stems, and branch are all the original specimen material.
Kingdom: Plantae, Phylum: Coniferophyta, Class: Pinopsida, Order: Coniferales, Family: Cheirolepidiaceae, Genus: Pararaucaria, Species: patagonica.
Exporting of all fossil from Argentina has been banned since 9-15-2003. The original branch and cones were collected and exported prior to this time. Once the existing supply (specimens exported prior to 9-15-03) is exhausted, you will only be able to purchase original specimens from private collections.
This specimen is from a private collection and is not currently available for sale!
