Description

Fossil Cycad Seed
#13
Jurassic Period
Cerro Cuadrado, Patagonia, Argentina
Cycads are an ancient group of seed plants. They first appeared in the Pennsylvanian Period and so have existed for approximately 300 million years, appearing before there were dinosaurs, existing alongside them, and perhaps being eaten by them. Unlike the dinosaurs, however, the cycads never became extinct; they are still with us, although they are not now as abundant or diverse as in their Mesozoic hey-day.
In the Mesozoic, cycads were an abundant component of the flora. During the Triassic and Jurassic, the time of their greatest diversity, cycads made up 20% of the world flora. For this reason the Mesozoic, and
especially the
JURASSIC
, is often referred to as the "Age of Cycads". During this time, they were an important component of the vegetation, not simply in numbers of species, but in size and number of individuals. Cycads were the trees and shrubs which, along with the conifers and Ginkgo-ales, dominated the Mesozoic forests.
The seed was found in Cerro Cuadrado, Patagonia, Argentina.
From the Jurassic Period (120 Million Years Ago).
The seed comes in a display box 3 1/4" x 4 1/4".
