Jurassic-era fossil leaves found in India
Fossilised leaves, estimated to be around 150-200 million years old, were discovered in Jharkhand’s Sahibganj district. The geologists say that they fall into the Jurassic period.
The team said 20 cm by 5 cm fossilised leaves of genus Ptilophyllum have been found in Dudhkol mountain in Taljhari area. The excavation is still underway.
Such leaves were consumed by herbivorous dinosaurs. Smaller fossils from the Upper Jurassic to Cretaceous period were earlier found in the region. The geologist also think they might even find fossilised dinosaur eggs during further excavation
The excavation is being conducted in association with National Botanical Research Institute, Lucknow under a project of the Department of Science and Technology of the Union government.
Earlier, several fossils were found in Maharajpur, Tarpahad, Garmi Pahad and Barharwa areas in Sahibganj and Sonajhari in neighbouring Pakur district.
During the Jurassic period, Earth's climate changed from hot and dry to humid and subtropical. This gave rise to many life forms and even many new dinosaurs emerged—in great numbers like stegosaurus, brachiosaurus, allosaurus. This period took place 199 to 145 million years ago.
