8. Egypt

The petrified wood from Egypt dates back to Oligocene epoch (~35 Mill. years). Up to now there is no exact determination of the  wood. The colours are mostly bright yellow-ochre and sometimes brown with red and grey. There are no roots, small limbs or petrified leaves found in this petrified forest. The desert near Cairo is rich with petrified wood. The layers are claimed to formed by one of the ancient branches of the river Nile. It carried the logs along and threw them into that place where they were buried and covered by volcanic ash. Full rounds are rare! The petrified forest of Cairo is a National Park and stringent protected. Petrified wood from Egypt is not often seen on rock shows.

10. Simbabwe

The petrified wood from Gokwe often has a superb preservation. Cell structure and the bark of the wood found here are in exellent conditions. Fairly frequently the wood from this place has a green coloring. It´s sometimes almost a emerald green! But real green wood from here is becomming scarce-no new green wood has been comming out of the site for the last years. The green colour is caused by traces of Chromium.
