Kolkata, November 11, 2016: A section of fossil records of Indian dinosaurs, described by British geologist Charles Matley in the early 20th century, are yet to be traced and some, which are housed in the Indian Museum here, have not even been restored, an expert said.

“Some of the collections which he (Matley) claimed were restored back to India are missing over the last 100 years. Some of the specimens are in a bad shape and improperly stored. The challenge is to describe the collected material and restore it.

“It is a big challenge to restore them as they are extremely fragile,” veteran palaeontologist D.M. Mohabey said at a national workshop on applications of palaeontology in archaeology at the museum on Wednesday.

“Restore the specimens which are misplaced. Some of the specimens packed in 1932 have not been opened yet. They are in writings of Matley,” he demanded.

Narrating the history of excavations of dinosaur fossils in India, Mohabey, a former Joint Director General of the Geological Survey of India (GSI), said the period 1917-33 was the first golden age of research on Indian dinosaurs when Matley carried out excavations in two expeditions (1917-1921 and 1932-1933) in the lameta sediments at Jabalpur (in now Madhya Pradesh) and at Pisdura (now Maharashtra).

Matley’s collections were subsequently distributed in three museums across the world: British Museum of Natural History (BMNH) (now the Natural History Museum), London, the American Museum of Natural History, New York (AMNH) and Indian Museum.

A major chunk of the excavated bones were shipped to the British and American museums for preparation and description, and subsequently returned to India and presently housed in Indian Museum and GSI, Kolkata, said Mohabey, adding the foreign museums still house critical specimens from the collection.

“But at the same time a section of the specimens that he had collected were never taken to Britain.

“They lie here only, in the galleries of the Indian Museum which the GSI maintains. Many are in the same stage in which he had excavated and packed… they are still like that. Some of the collections were never opened,” he said.

The GSI and the University of Michigan have recently embarked on a programme to recover missing fossil bones in museum collections and to collect new bones from field sites.

Oldest Evidence of Life on Earth Found in Eastern Canada, Says New Research

The recent research indicates that microbial life emerged earlier than previously known and relatively soon after the Earth's formation

Canada, September 29, 2017 : Rocky outcrops in eastern Canada contain what may be some of the oldest evidence of life on Earth, dating back about 3.95 billion years.

Scientists said on September 27 that they found earliest indirect evidence of life on Earth in the form of bits of graphite contained in sedimentary rocks from northern Labrador that they believe are remnants of primordial marine microorganisms.

The researchers carried out a geological analysis of the Labrador rocks and measured concentrations and isotope compositions of the graphite, and concluded that it was produced by a living organism.

They did not find fossils of the microorganisms that may have left behind the graphite, a form of carbon, but said they may have been bacteria.

“The organisms inhabited an open ocean,” said University of Tokyo geologist Tsuyoshi Komiya, who led the study published in the journal Science.

Earth formed about 4.5 billion years ago and the oceans appeared roughly 4.4 billion years ago. The new study and some other recent research indicate that microbial life emerged earlier than previously known and relatively soon after the Earth’s formation.

Canada has produced some of the most ancient signs of life on Earth.

Another team of scientists in March reported that microfossils between 3.77 billion and 4.28 billion years old found in northern Quebec, relatively close to the Labrador site, are similar to the bacteria that thrive today around sea floor hydrothermal vents.

Other scientists last year described 3.7 billion-year-old fossilized microbial mats, called stromatolites, from Greenland. (VOA)

Sept 19, 2017: Autumn is the season of the year that sees the Hindus, all geared up to celebrate some of the biggest festivals of India. The festive spirit in the Bengalis all enthused to prepare for the greatest of the festivals, the ‘Durga Puja’.

About Mahalaya:

Mahalaya is the auspicious occasion that marks the beginning of “Devipaksha” and the ending of “Pitripaksha,” and this year it is celebrated on September 19.

Observed exactly a week before the ‘Durga Puja’, Mahalaya is the harbinger of the arrival of Goddess Durga. It is celebrated to invoke the goddess possessing supreme power! The goddess is invited to descend on earth and she is welcomed with devotional songs and holy chants of mantras. On this day, the eye is drawn in the idols of the Goddess by the artisans marking the initiation of “Devipaksha”. Mahalaya arrives and the countdown to the Durga Puja begins!

The day of Mahalaya bears supreme significance to the Bengalis. The day is immensely important because on this day people throng to the holy river Ganges in order to pay homage to their ancestors and forefathers. Clad in white dhotis, people offer prayers and take dips in the river while praying for their demised dear ones. The ritual is popular as “Torpon”.

As per Hindu myth, on “Devipaksha”, the Gods and the Goddesses began their preparations to celebrate “Mahamaya” or Goddess Durga, who was brought upon by the trinity- Brahma, Vishnu, and Maheshwara; to annihilate the fierce demon king named Mahishasura. The captivating story of the Goddess defeating the demon got popularized with the goddess being revered as “Durgatinashini” or the one who banishes all the evils and miseries of the world. The victory of the Goddess is celebrated as ‘Durga Puja’.

The program is inseparable from Mahalaya and has been going on for over six decades till date. The magic is induced by the popular Birendra Krishna Bhadra whose voice makes the recitation of the “Chandi Kavya” even more magnificent! He has been a legend and the dawn of Mahalaya turns insipid without the reverberating and enchanting voice of the legendary man.

Mahalaya will keep spreading the magic and setting the vigor of the greatest festival of the Bengalis- the Durga Puja, to worship the supreme Goddess, eternally.

Was Human Evolution an Accidental Progression?

  • A new study indicates that human evolution may not have been due to the climate change
  • Andrew Barr from George Washington University says that evolution may have happened by chance
  • There is no set-in-stone rule that species evolve due to climate change, it’s not yet discovered as to what causes change in this pulse

August 07, 2017: A new study says that origin of human genus could have occurred by chance and might not be directly related to climate change, as commonly believed.

Many scientists have argued that an influx, described as a “pulse”, of new animal species appears in the African fossil record between 2.8 and 2.5 million years ago, including our own genus Homo.

Experts believe it takes a broad-scale event like global climate change to spark the origination of so many diverse new species.

However, the new study, published in the journal Paleobiology, says it is possible the pulse of new species could have occurred by chance.

“The idea that our genus originated more than 2.5 million years ago as part of a turnover pulse in direct response to climate change has a deep history in paleoanthropology,” said Andrew Barr from George Washington University.

“My study shows that the magnitude of that pulse could be caused by random fluctuations in speciation rates. One implication is that we may need to broaden our search for why our genus arose at that time and place,” Barr said.

It is generally accepted that when major environmental changes occur, some species will go extinct and others will originate, which can create a cluster or pulse of new species in the fossil record.

However, there is not a set definition of what is considered a pulse, so experts have disagreed about which clusters constitute meaningful events and which can be explained as random fluctuations.

Barr used computer simulation to model what the fossil record might look like over time in the absence of any climate change and found clusters of species originations that were of similar magnitude to the clusters observed in the fossil record.

This means random patterns are likely under-credited for their role in speciation fluctuation, he said.

The findings mean scientists may need to rethink widely-accepted ideas about why human ancestors became smarter and more sophisticated. (IANS)
