In addition to conifers, fossils of other plants were found in the Petrified Forest National Park: ferns, lycopods, cycads, ginkgo, etc.

The park is divided into two areas – north and south. In the northern part of the park, there is a part of the multi-colored badlands (a type of dry relief, where the softest sedimentary rocks and clay-rich soils were subject to extensive wind and water erosion), formed in the Triassic period, called the colored desert. In the southern area, there are numerous deposits of petrified wood, as well as several petroglyphs.

Petrified Forest National Park is famous for its fossils, especially of trees that grew on Earth about 225 million years ago, at the end of the Triassic period of the Mesozoic era. At the time, the region where the park is now located was located near the equator, in the southwestern part of the Pangea supercontinent, and was characterized by a humid subtropical climate. The site, now northeastern Arizona, was covered by a plain bounded by mountains to the south and southeast and an ocean to the west. (more…)
