Several animal species, which are either extinct or seen only in Africa, thrived 40,000 to 50,000 years ago in the wilds of Purulia, Bankura and West Midnapore districts, according to senior scientists of the Zoological Survey of India.
The species include a Siwalik Antelope, Siwalik Nilgai, Siwalik Cattle, Porcupine (Hystrix Crassidens), Siwalik Equid, African Lion (Panthera Cf. Leo), Siwalik Elephant, Giraffe, Spotted Hyenas, a recent report published by the Zoological Survey of India said.
Siwalik Antelope, Siwalik Nilgai, Siwalik Cattle, Porcupine (Hystrix Crassidens), Siwalik Equid and Siwalik Elephant disappeared from the face of earth several thousand years ago.
However, African Lion (Panthera Cf. Leo),Giraffe, Spotted Hyenas are now only found in Africa.
A senior palaeontologist of the ZSI, T K Pal, along with his team had several years back stumbled upon the remains of these animals preserved in two caves located in the Susunia Hills of Bankura.
"In the early 80s, to be specific 1980-81, we had recovered remains of the animals from the caves of Susunia and other surrounding areas of Jangalmahal," Pal said.
The remains were preserved in the ZSI laboratory and it was decided to conduct tests on them to determine their age prior to publishing a full report on the zoo-archaeological remains of Bengal.
"The lab tests revealed that the animal remains were 50,000 years old," Pal told PTI.
According to ZSI, this constitutes the first such kind of discovery in West Bengal and for that matter eastern India.
Pal said, "Several experiments have shown that in the area, now spanning the three districts, the land mass, geology and climate were not the same as now. The sea level, including that of the Red sea, was then much lower and there existed an African route stretching from today's Himalyan region to Africa through Afghanistan and Pakistan."
The emeritus scientist explained that Gondwana land mass — the super continent that comprised most of the landmasses of today's southern hemisphere, including Australia, Madagascar, Antarctica, South America, Arabian Peninsula and Indian Sub-continent, bumped into the Eurasian landmass creating the African route for the animals to migrate and roam into these areas in search of food and water.
"The roaming area of the animals was much larger then and the animal corridors streched from one part of the globe to another. From parts of Africa to today's Himalayas, which was then known as Siwalik Hills, the youngest east-west mountain chain of
