New Delhi, Three years after it was lambasted by a parliamentary panel for failing to maintain the National Museum of Natural History, the environment ministry is all set to construct a new, state-of-the-art facility in the capital. Interior_view_-_National_Museum,_New_Delhi_-_IMG_2206

The Ministry of Environment, Forests and Climate Change has invited bids for the construction of a new museum building complex at Bhairon Marg, behind the Old Fort and opposite an international expo complex that will have modern facilities like an IMAX theatre as well as an open-air seating for 500.

Also to do its bit for conserving energy, the new building will have to achieve LEED India Platinum Rating as well as the GRIHA 5-star rating. Spread across 6.5 acres, the museum is expected to be built at a cost of Rs.250 crore within 43 months after the commencement of its construction.

LEED (Leadership in Energy and Environmental Design) plaque is a US green building certification programme that recognises best-in-class building strategies and practices, while GRIHA (Green Rating for Integrated Habitat Assessment) is India’s national rating system.

The Rs 209 crore Indira Paryavaran Bhawan that houses the office of environment ministry is India’s first ‘Net Zero Building’ that produces its own energy and has achieved the LEED India Platinum Rating as well as the GRIHA 5 star rating.

“We have invited online bids-eligibility bid, technical bid and financial bid-from eligible consultants and architectural firms for the consultancy services (to build the museum),” a ministry official said.

Noting that the required services have to be planned at minimum cost, maintenance and lowest consumption of energy and water, the official said that the complex will also house auditoriums, offices, underground parking, permanent and temporary galleries and eco-classrooms, among many other features.

Delhi got its first National Museum of Natural History on June 5, 1978, coinciding with the World Environment Day.

Situated at Tansen Marg in Lutyen’s Delhi, the museum owes its genesis to then prime minister Indira Gandhi, who declared that the country needed such a museum to depict its flora, fauna and mineral wealth to promote environmental awareness among the masses.

However, the Lok Sabha’s Public Accounts Committee, under the ruling Bharatiya Janata Party’s chairmanship of Murli Manohar Joshi, had in a scathing report in 2012 pulled up the environment ministry over the “pathetic functioning” of the museum.

It had recommended that the government set up a permanent state-of-the-art museum which at present is operating out of a rented building owned by an industry lobby.

The committee had also sought the involvement of students in surveying fauna and flora in their vicinity and in afforestation, along with disseminating environmental awareness and heightening environmental concerns across the country.

Angola Fossils Bring A New But Familiar Ocean in View

These fossils are the patrimony of Angola, these are their heritage, and for us to be able to bring them to the Smithsonian and ultimately back to Angola.

Some may be familiar with mythical sea monsters. For example, Scotland’s infamous Loch Ness Monster “Nessie,” and Giganto — fictional beasts of comic book fame. But millions of years ago, real-life sea monsters lived and thrived in what we now call the South Atlantic Ocean.

South Atlantic Ocean basin

As the continents of South America and Africa separated millions of years ago, scientists say a fantastic array of ferocious predators and other lifeforms colonized the newly formed body of water off the coast of Angola.

That diverse collection of marine reptiles included mosasaurs (aquatic lizards), plesiosaurs (which exhibited broad flat bodies, large paddlelike limbs, and typically a long flexible neck and small head), and the more familiar giant sea turtles.

But a catastrophic asteroid that hit earth 66 million years ago wiped most of them out, according to scientists.

Today, thanks to a project called Projecto PaleoAngola among Angolan, American, Portuguese and Dutch researchers, paleontologists have been able to visit the coastal cliffs of Angola to excavate and study what remains of these giant animals.

“We knew that there were fossils there, we just didn’t know how good they would be,” says Louis Jacobs, collaborating curator and professor emeritus of paleontology at Southern Methodist University in Dallas, Texas.

“Nobody had been there, so this was a vast, unknown terrain and we wanted to get there.”

A 72-million year-old ecosystem

What the team of paleontologists discovered was a treasure trove, giving them an unprecedented look into a strange yet familiar ecosystem.

In addition to mosasaurs, plesiosaurs and sea turtles, there were fossilized remains of a variety of fish and other marine life forms.

While mosasaurs have been known to exist on all continents and are relatively common in certain places, this particular sample is the largest collection of southern hemisphere mosasaurs known, according to the paleontologists.

“It’s certainly the best locality for these kinds of animals in sub-Saharan Africa and it could be one of the best in the world,” Jacobs said.

Rediscovering a lost world

Eleven authentic fossils from Angola’s ancient seas, full-size reconstructions of a mosasaur and an ancient sea turtle are on display for the first time in a new exhibit at the Smithsonian’s National Museum of Natural History in Washington, titled “Sea Monsters Unearthed: Life in Angola’s Ancient Seas.”

There are also 3-D scanned replicas of mosasaur skulls, and photo-murals and video vignettes transport visitors to field sites along Angola’s modern rugged coast, where Projecto PaleoAngola scientists unearthed the fossil remains from this lost world.

Jacobs, who was part of a team of scientists and students at SMU that helped prepare the fossils for the Smithsonian exhibit, says any visitor “can look and see and compare how the ecosystem and its animals of the cretaceous of 72 million years ago are similar to ecosystems today in the same general areas.”

“The species are different, but the ecological jobs of the species are very similar,” he added.

Giant lizards

Michael Polcyn, senior research fellow at SMU, pointed out an example in the exhibit.

Standing in front of a fossil skull and partial skeleton of a mosasaur, he described the reptile as an “optimized fish eater.”

“You see the long narrow snout, the interlocking teeth — this would be similar to what you would see in the ocean today, in a dolphin for instance,” he said.

He gestured to a graphic posted on the display case depicting a rough toothed dolphin which it described as “the analog for the animal in the modern ecosystem.”

Shell-crushing mosasaur

Another great example of diversity within that ancient ecosystem is the hardshell-eating mosasaur, Polcyn said, which preyed on large oysters which were almost a meter (three feet) across.

“They were really big, so to crack an oyster three feet across you needed the dentition and the musculature to do that, and that’s what you see here in these very strange mushroom-shaped teeth that you see in this animal,” Polcyn explained.

Within the same ecosystem was another example of a top predator, the Prognathodon kianda. Its full-scale skeleton on display in the museum is almost eight meters long.

In addition to top predators like the monster-like mosasaur, the exhibit also includes fossils of gentler creatures; small fish and an ancient giant sea turtle.

“We have a snapshot of this moment in time 72 million years ago that has preserved all of these animals that were living together in one place,” Polcyn said.

The big dig

Jacobs says the fossil find in Angola was a big deal for a number of reasons:

“First of all because it’s going into a country that never really had a heritage of fossils,” he said. “It basically was unknown at the level that we are opening it up.”

“Fossils,” he says, “instill a sense of pride in what’s in the country, and it provides something to use for education, and it builds science. And the way it builds science is because every country has fossils, so every country has something to offer, so every country is a piece of the puzzle and the Angola piece is now there.”

Michael Polcyn agrees that unearthing this cache of ancient fossils has been a huge breakthrough on a number of fronts.

“From a purely scientific point of view it gives us an incredible window into an ecosystem 72 million years ago that is relatively complete,” he says. “From a very human point of view this really shows the people of Angola, and the people of the world, what incredible resources we have in our natural environments.”

And lastly, he says, “These fossils are the patrimony of Angola, these are their heritage, and for us to be able to bring them to the Smithsonian and ultimately back to Angola, on a very personal level, is a thrill for us.” (VOA)
