Two fossils dating back 25 million years were found in Makum coalfield in Assam.
With over 49,000 plant species reported as of 2018, India holds about 11.5% of all flora in the world.
Now, a new fossil record has shown that India is the birthplace of Asian bamboo, and they were formed about 25 million years ago in the north-eastern part of the country.
These belonged to the late Oligocene period of about 25 million years ago.
Yunnan Province in China now has the highest diversity of bamboo, but the oldest fossil in that region is less than 20 million years old.
It is clearly indicating that Asian bamboo was born in India and then migrated there.
This finding further strengthens the theory that bamboo came to Asia from India and not from Europe.
The European bamboo fossil is about 50 million years old.
Bamboo fossils are not very common in India as they are known only from the Siwalik sediments at Himalayas.
