Spectacular fossil forests have been found in the coal mines of Illinois by a US-UK team of researchers.
The group reported one discovery last year, but has since identified a further five examples.
The ancient vegetation - now turned to rock - is visible in the ceilings of mines covering thousands of hectares.
These were among the first forests to evolve on the planet, Dr Howard Falcon-Lang told the British Association Science Festival in Liverpool.

Spectacular discoveries of fossil forests show that global warming wiped out the first rainforests to evolve on our planet.

The fossil forests were found in underground coalmines in Illinois by a team led by Dr Howard Falcon-Lang of the University of Bristol and scientists from the Smithsonian Institution and the Illinois Geological Survey.

The new research will be publicised at an event on Climate change in the past: the latest evidence from fossil plants and animals at the BA Festival of Science in Liverpool on Monday 8 September.

Arizona's Petrified Forest
Permalink  
 


Imagine the Greek goddess Medusa was real, not a myth, and that she visited an Arizona forest in the prehistoric past, turning many of the trees to stone with her magical gaze.
That fantasy land wouldn't be much different from what you actually see in northeastern Arizona today.
Petrified Forest National Park, about 100 miles east of Flagstaff off I-40, is centred around what is believed to be the world's largest concentrations of petrified wood, dating from some 225 million years ago.

In a period now lost in time our region bore no resemblance to the landscape we see today. Dinosaurs ruled and great, luxuriant forests covered every inch of the territory.
Over millions of years great changes occurred. At some point, the dinosaurs and the enormous forests disappeared, giving way to new species of animals and plants. The causes of this extraordinary event have been lost to us and are wreathed in mystery.
Today, the vestiges of those forests, transformed into stone through the process of fossilisation, seem to awaken from their long sleep to reveal to us a small part of that enigma which is the prehistory of our planet.
Although animal fossils are found all over the world, fossilized plant remains exist in very few countries, a fact that makes this remarkable location here in Peru even more noteworthy.

Robledo petrified wood

The Robledo Mountains' reputation as one of the world's most important landscapes of pre-dinosaur fossil trackways likely will be enhanced by another discovery petrified wood slowly emerging from the desert floor.

"There are just so many types of fossils here, it just staggers the mind" - Jerry MacDonald of Las Cruces, the amateur palaeontologist who discovered the Permian Period fossil trackways in the late 1980s and more recently found the dozens of locations with petrified wood.

An ancient forest of cypress trees, estimated to be eight million years old, has been discovered in Hungary.
Archaeologists found the 16 preserved trunks in an open cast coal mine in the north-eastern city of Bukkabrany.

Hungarian scientists said on July 31 they had discovered a group of fossilised swamp cypress trees preserved from 8 million years ago which could provide clues about the climate of pre-historic times.
Instead of petrifying - turning to stone - the wood of 16 Taxodium trees was preserved in an open-cast coal mine allowing geologists to study samples as if they were sections cut from a piece of living wood.

Hungary Fossilised trees

Archaeologists have found an 8-million-year old forest of cypresses, well preserved and not fossilized, in Bukkabrany in northeastern Hungary.

"The discovery is exceptional as the trees kept their wooden structure, they neither turned into coal nor were petrified" -  Tamas Pusztai, the deputy director and head of the archaeological department at the local Otto Herman museum, who oversaw the excavation.

It may look like a haunted forestbut this rare cluster of fossilized trees is luring scientists in, not scaring them away.
The eight-million-year-old swamp cypress forest was found recently near the village of Bukkabrany in northeastern Hungary, officials announced today. Miners uncovered the unusual find while digging for lignite, or brown coal.
The remains of the 16 uncovered treeswhich range from about 4 to 6 meters tall and 1.5 to 3 meters aroundare an oddity because they did not petrify, or turn to stone, as preserved trees usually do.

A rare tree fossil was found in the Chinese  city of Zigong in Sichuan Province.
Geologists believe that fossilised wood could have been a large arboresque tree, measuring was ten meters in height, and almost one meter in diameter, during its lifetime, during the earlier part of the middle of the Jurassic Period. It had been demonstrated that there were many big trees in Zigong at that time, which provided much food for the dinosaurs.

Currently, an exhibition hall for the fossil tree has already been proposed as a new tourist destination.
