A secret of millions year ago, Fossil forest in hills and hillocs in sexi Peru. Peru Forest buried from a Volcanic eruption 39 millions years ago. We began to piece together the story of the forest, We first visited these petrified trees more than 20 years ago.
The studies says volcanic processes that preserved the fossils, by dating the rock. The light of day again saw stripping leaves from the trees and fossils wood. Then flows of ashy material moved through, breaking off the trees and carrying them like logs in a river to the area where they were buried and preserved.
Millions of years later, after the modern-day Andes rose and carried the fossils with them, Ash rained down on the forest that day. The New World tropics and the past climates and environments of South America, In the first fossil forest, petrified forest, El Bosque Perificado Piedra chanana.
By examining thin slices of petrified wood under microscopes, we were able to map out the mix of trees that thrived here long before humans existed.
The site was not so easy because of the volume and diversity of fossil wood. The petrified wood that could be studied under a microscope, had grow in the forest before the eruption, to figure out the types of trees.
The living-tissue component of the wood are features that could be observed carried water upwards within the tree or the presence of tree rings and the naked eye or with small hand-held microscopes, things like the arrangement and width of the vessels. We cut small blocks from the specimens, and from those we were able to prepare petrographic thin sections in three planes.
They allow us to see many detailed features relating to the vessels, the wood fibers. Each plane gives us a different view of the tree’s anatomy. The forests of South America like Hura, or sandbox tree ; Anacardium, a type of cashew tree; and Ochroma, or balsa, the legume family of a tree the Sexi site – a fossil trunk about 2.5 feet (75 cm) in diameter – has features like those of Cynometra.
More evidence that the forest was growing at a low elevation near the sea before the Andes rose. The geologic past when the Earth was much wanner than today, All had smooth edges, rather than the toothed edges or lobes that are more common the forest was growing at a time cooler climates of the mid- to high latitudes, indicating that the forest experienced quite warm conditions.
The tropical seas ancient forest certainly would have supported no fossils of mammals, birds or reptiles from the same time period have been found at the Sexi site, the world of 39 million years ago two important groups of animals –monkeys and rodent. The time the fossil forest was growing continent which include guinea pigs.
Many of the fossil trees have close relatives in the present-day lowland tropical forests of South America.
Other locations with fossil trees include Florissant, which has giant petrified redwood stumps, and Petrifed forest national park in Arizona, this ancient forest was like expanded when we had an opportunity to collaborate. We knew from our investigation that many of the fossil trees were like
Working with the artist, who is also a paleontologist, made us think critically about many things: What would the forest have looked like? Were the trees evergreen or deciduous? Which were tall and which shorter? What would they have looked like in flower or in fruit flooded-forest location, but what about the vegetation growing back from the watercourses on higher ground? Would the hills have been forested or supported drier-adapted vegetation?
