Bosques Petrificados de Jaramillo National Park
National Park National park protecting extensive petrified forest fossils
This Santa Cruz park preserves petrified tree trunks and fossil sites; paleontology trails and guided visits appeal to those interested in ancient forests and Patagonia’s deep‑time geology.
Bosques Petrificados de Jaramillo National Park is a protected area in Santa Cruz Province in Argentine Patagonia that preserves extensive deposits of fossilized wood. It is noted for concentrations of petrified tree trunks and other paleobotanical remains.
The park contains outcrops and scattered fossil trunks that can be observed at surface exposures and along low trails. Interpretation is generally focused on the fossil wood and the processes that turned ancient trees to stone rather than on built visitor facilities.
Fossil material at the site represents ancient forests that were buried and mineralized; the preserved trunks and fragments are the primary scientific and tourist interest. The area is managed for conservation and scientific study of paleobotany and paleoecology.
The park lies in central-southern Santa Cruz Province in the Patagonian steppe region of Argentina. It is remote and accessed from local roads in the province rather than from a major urban center.
