The crown of a prehistoric tree found in a sandstone quarry in Gilboa, N.Y., has shed light on the look of the world's earliest forests believed to have thrived during the Devonian period between 360 million and 397 million years ago.
The 2004 discovery of this 380-million year-old, six-foot uppermost portion of an ancient tree trunk allowed paleobotanists to create a composite picture of the entire plant when they put it together with fragments of a trunk found a the same site a year later and with tree stumps recovered more than 130 years ago in another rock quarry 10 miles away. The remains have been widely touted as "evidence of the Earth's oldest forest," according to a report published in this week's Nature.

An 80 million-year-old petrified tree stump found in northwestern Uzbekistan could unlock the secrets of flourishing ancient plant life in what is now a bleak Central Asian landscape, Uzbek scientists said on Monday.
The tree trunk, which is two meters long and 33 centimetres in diameter, was petrified as a result of a volcanic eruption and was found during excavations in the fossil-rich Sulton Uvaisy mountain range near the Amudaria river.

"The Sulton Uvaisy mountain range is widely known by the world's palaeontologists, and many dinosaur remains have been found here" - Azimboi Sadullayev, Uzbek researcher, head of the Khorezm Mamun Academy.

But before the trunk was uncovered, "we had no findings that could give us an idea about the plants that flourished here 100-150 million years ago" .

A sample of the stony tree was sent to a nuclear physics institute for further research and to identify its exact age. Scientists at the academy, which was founded here in the 10th century, are now developing new strains of plants that can grow in what has become salty, environmentally devastated land.

Geologists in Gujarat are thrilled after a massive fossilised tree of Jurassic age was recently discovered at Dholavira -- an ancient metropolitan city of the Harrapan civilisation which is now an archaeological site in the Rann of Kutch.

"It is an amazing find. The fossil-tree is at least 176 million years old and appears to be of the Jurassic age. We have not seen anything like it ever before" - Dr K C Tewari, principle investigator at the Geology department of the MS University, Vadodara, who studied samples of the fossil.
