This is the story about the most incredible fossil cones in the world: the cones of the Jurassic aged Araucariaceae trees from the petrified forests of Patagonia (Argentina, South America). Mr. Dernbach takes you through the history of petrified wood, collecting in Patagonia, and also talks about the similarities between Cerro Cuadrado and the Arizona petrified forest. A fantastic glossary in the back helps the reader understand some of the terms used. The text, German and English, is very enjoyable reading and the photos are simply stunning. An effortless and entertaining read.
