Dangerously poor air quality on Monday forced Pakistani authorities in the cultural capital of Lahore to close primary schools for a week, government officials said, after the air-quality index hit a record high over the weekend.

The measures in Lahore were part of a larger effort to protect children from respiratory-related and other diseases in the city of 14 million people. The government said everyone in Lahore was required to wear a face mask.

Fifty percent of employees must also work from home as part of a “green lockdown” in the city, the government said, adding that barbecuing food without filters was banned and motorized rickshaws restricted. Wedding halls must close at 10 p.m. and artificial rain is likely to be used to combat the pollution.

The air-quality index in Lahore exceeded 1,000 over the weekend, a record high in Pakistan.

Toxic gray smog has sickened tens of thousands of people, mainly children and elderly people, since last month when the air quality started worsening in Lahore, the capital of eastern Punjab province bordering India.

The government has also banned construction work in certain areas and fined owners of smoke-emitting vehicles. Schools will remain closed for a week because of the pollution, according to a government notification.

The concentration of PM 2.5, or tiny particulate matter, in the air approached 450, considered hazardous, the Punjab Environment Protection Department said.

Lahore was once known as a city of gardens, which were ubiquitous during the Mughal era from the 16th to 19th centuries. But rapid urbanization and surging population growth have left little room for greenery.

A worker digging up clay in a southern England limestone quarry noticed unusual bumps that led to the discovery of a “dinosaur highway” and nearly 200 tracks that date back 166 million years, researchers said Thursday.

The extraordinary find made after a team of more than 100 people excavated the Dewars Farm Quarry, in Oxfordshire, in June expands upon previous paleontology work in the area and offers greater insights into the Middle Jurassic period, researchers at the universities of Oxford and Birmingham said.

“These footprints offer an extraordinary window into the lives of dinosaurs, revealing details about their movements, interactions, and the tropical environment they inhabited,” said Kirsty Edgar, a micropaleontology professor at the University of Birmingham, The AP reported.

Four of the sets of tracks that make up the so-called highway show paths taken by gigantic, long-necked, herbivores called sauropods, thought to be Cetiosaurus, a dinosaur that grew to nearly 60 feet (18 meters) in length. A fifth set belonged to the Megalosaurus, a ferocious 9-meter predator that left a distinctive triple-claw print and was the first dinosaur to be scientifically named two centuries ago.

An area where the tracks cross raises questions about possible interactions between the carnivores and herbivores.

“Scientists have known about and been studying Megalosaurus for longer than any other dinosaur on Earth, and yet these recent discoveries prove there is still new evidence of these animals out there, waiting to be found," said Emma Nicholls, a vertebrate paleontologist at the Oxford University Museum of Natural History.

Nearly 30 years ago, 40 sets of footprints discovered in a limestone quarry in the area were considered one of the world's most scientifically important dinosaur track sites. But that area is mostly inaccessible now and there's limited photographic evidence because it predated the use of digital cameras and drones to record the findings.

The group that worked at the site this summer took more than 20,000 digital images and used drones to create 3-D models of the prints. The trove of documentation will aid future studies and could shed light on the size of the dinosaurs, how they walked and the speed at which they moved.

“The preservation is so detailed that we can see how the mud was deformed as the dinosaur’s feet squelched in and out," said Duncan Murdock, an earth scientist at the Oxford museum. "Along with other fossils like burrows, shells and plants we can bring to life the muddy lagoon environment the dinosaurs walked through.”

The findings will be shown at a new exhibit at the museum and also broadcast on the BBC's “Digging for Britain” program next week.
