First fossil proof found that long-necked dinosaurs were vegetarians
But there were hints of a diet full of green stuff.
Fossils of sauropods, which stomped across the planet for 130 million years, are plentiful; additionally, herbivores tend to outnumber those of carnivores. The animals had small, peglike teeth, and their huge, lumbering bodies seemed ill equipped to chase down prey. 'Plants were pretty much the only option,' said Stephen Poropat, a paleontologist and the deputy director of the Western Australian Organic and Isotope Geochemistry Center at Curtin University in Perth.
A study published in the journal Current Biology provides what may be the first concrete proof to support this argument, in the form of fossilized plants discovered in the belly of a sauropod. 'It's the smoking gun, or the steaming guts, as it were — the actual direct evidence in the belly of the beast,' Poropat said.
Poropat, along with scientists and volunteers from the Australian Age of Dinosaurs Museum, encountered the fossil on a dig in Queensland, Australia, in 2017. — KATE GOLEMBIEWSKI ?NYT

'Jurassic World: Rebirth' roars to top of N.American box office
"Jurassic World: Rebirth" -- the latest installment in the blockbuster dinosaur saga -- stomped the July 4th weekend competition at the North American box office, raking in a whopping $91.5 million in its debut, industry estimates showed Sunday. The Universal film, starring Scarlett Johansson, Jonathan Bailey and Mahershala Ali, takes viewers to an abandoned island research facility for the original Jurassic Park theme park, where secrets -- and genetically mutated dinosaurs -- are lurking. "This is an excellent opening for the 7th episode of an action-adventure monster series," said analyst David A. Gross of Franchise Entertainment Research. "The series has been especially good overseas and so far foreign business is outstanding. Dinosaur action is understood in all languages and across all cultures." "F1: The Movie," the Apple and Warner Bros. flick starring Brad Pitt as a washed-up Formula One driver who gets one last shot at redemption, slipped to second place at $26.1 million, Exhibitor Relations said. "How to Train Your Dragon," Universal and DreamWorks Animation's live-action reboot of the popular 2010 film, held in third place at $11 million. The family-friendly film tells the story of a Viking named Hiccup (Mason Thames) who strikes up a friendship with Toothless the dragon. In fourth place was Disney/Pixar Animation's latest original film "Elio," at $5.7 million in the United States and Canada. "Elio" tells the story of a young boy who is mistaken by aliens as an intergalactic ambassador for Earth. The voice cast includes Oscar winner Zoe Saldana. In fifth place was Columbia Pictures' zombie sequel "28 Years Later," which took in $4.6 million. The Danny Boyle-directed threequel picks up -- as the title suggests -- more than a generation after the initial outbreak of the Rage Virus. Rounding out the top 10 were:"M3GAN 2.0" ($3.8 million); "Lilo & Stitch" ($3.8 million); "Mission: Impossible -- The Final Reckoning" ($2.7 million); "Materialists" ($1.3 million) "Ballerina" ($725,000) —AFP

The effects of fireworks on animals and people
The rockets, explosions and cascading colours of fireworks are a staple of celebrations throughout the world, whether at the Fourth of July, Diwali or New Year's Eve. But while the clamour of light and sound brings out cheers from revelers, fireworks can cause panic in animals. They also leave behind trails of pollution that take a lingering toll on the environment and people. Here is what to know about the harm fireworks cause and recommendations from experts on how people can celebrate while reducing the impact. The intense, erratic sounds and lights from fireworks frighten animals, both wild and domesticated. Fear and stress responses have been documented in pets, zoo animals and wildlife. Wild animals may flee when fireworks start: Weather radars have recorded masses of birds taking flight and studies have shown fleeing by sea lions and seals. This rush to escape costs the animals energy and can lead to longer-term damage, said Bill Bateman, a professor of ecology at Curtin University in Australia and the author on a review of global research on the impact of fireworks on the environment. The animals may abandon habitats completely, or return with less energy for regular survival. These effects are worse when fireworks occur during migration and breeding seasons. Independence Day in the United States, for example, falls in the breeding season for many coastal birds. Shorebirds are particularly at risk because of their proximity to fireworks and beach crowds, said Nicole Michel, director of quantitative science at the National Audubon Society. Birds frightened by fireworks may abandon their nests, leaving chicks or eggs behind and exposed to threats like predators. And adult birds are already running at the end of their energy reserves by this time, Michel said. They may be eating less while sitting on nests or burning more energy as they feed themselves and their chicks. 'These poor birds are just run ragged,' she said. 'It's additional stress for a bird that's already very stressed'. Occasionally, fireworks kill large numbers of birds. In Beebe, Arkansas, in 2011 and 2012, thousands of blackbirds died after New Year's after being startled by fireworks. In 2022, fireworks in Taylor, Texas, caused nesting egrets to scatter, leading several to strike power transformers. 'Many of these birds, they're not nocturnal and they're flying low. They are surrounded by buildings and trees,' Bateman said. 'It's probably not a surprise that they end up piling into these things.' Fireworks cause short-term surges in air pollution and leave behind toxins in waterways and soil that harm people and wildlife over the long term. 'Bursting fireworks produce a thick particulate smoke that's laden with lots of nasty chemicals,' Bateman said. Studies have shown that air worsens in the hours after fireworks, containing particulate matter, metals and gases like sulfur dioxide. Levels are higher after celebrations where fireworks use is high over multiple days. Air pollution aggravates lung and heart disease and is linked to other health conditions. Chemicals linked to fireworks, including perchlorate, have also been detected in water bodies. Fireworks are also commonly made with and wrapped in plastic and leave behind debris that can be ingested by animals and break down into microplastics. One study found New Year's fireworks in London caused an immediate spike in microplastics. 'Firework displays are spectacular and culturally important,' Bateman said, 'and if there are options that are more environmentally friendly, then we really, really should embrace those'. With traditional fireworks, damage can by reduced by shortening the length of shows and number of fireworks used and moving them farther from people and animals. Community displays, staged high in the air, are better than firing fireworks individually, experts said. 'People just setting off fireworks all over the place are going to impact far more birds just because it is more spread out,' Michel said. 'There's also the risk of starting a fire, which would then destroy habitat'. Drone light shows are increasing in popularity. They are quieter and don't release the intense bursts of pollution associated with fireworks, though they still carry some smaller risks. Several cities and venues have swapped firework spectacles for drones in recent years, citing concerns over wildfires, pollution and wildlife. This week, the town of Hingham, Massachusetts, held its first Independence Day show using drones set to the music of a live band instead of fireworks. The town is home to a colony of nesting American oystercatchers that have settled on the islands in its harbour in recent years. In order to protect the birds, fireworks are not an option, said Marco Boer, chair of the Hingham Harbour Development Committee, which organised the event. Boer said he had worried that people might miss the 'big bang' of fireworks but that his community's response to Wednesday's drone show was 'overwhelmingly positive'.

‘Jurassic World: Rebirth' brings fans back to dangerous dinosaur realm
Scarlett Johansson's role in "Jurassic World: Rebirth" made her recall her earliest memories of the dinosaur film franchise. The "Black Widow" actor recalled seeing the first "Jurassic Park" film at the movie theater when she was 10 years old. "It imprinted on me very deeply,' she told Reuters at the London premiere at Odeon Luxe Leicester Square. "For the next three decades, I was like, I would have done anything to be in a Jurassic movie in any capacity,' she added. The franchise, created by Michael Crichton, has spawned several films, merchandising deals and video games. "Jurassic World: Rebirth," directed by Gareth Edwards, follows a team of specialists that embarks on an expedition to a forbidden island, home to a research facility for the original "Jurassic Park'. The specialists, played by Johansson and "Bridgerton" actor Jonathan Bailey, must obtain DNA samples from three dinosaurs to achieve a life-saving medical breakthrough. The Universal Pictures film arrives in theaters on July 2. For Rupert Friend, this installment in the franchise is exhilarating. "I love adventure. I love being taken on a ride where you don't know what's going to happen. I love the unknown. I love risk,' he said. For well-known science fiction director, Edwards, the pressure for the film to succeed did not hit until he arrived at the premiere. "It's all front and centre here. It feels a bit weird to be honest. I can't quite get my head around it,' the "Rogue One: A Star Wars Story" director added. —Reuters
