Aussie fossils reveal historic discovery
A landmark discovery has revealed the previously-unknown existence of a large apex predator on the prehistoric Australian continent and uncovered a predator hierarchy unique to the region.
The research describes five theropod fossils discovered between 1988 and 2023 in Bunurong/Boonwurrung Country (Bass Coast) and the Eastern Marr Country (Otway Coast).
Theropods are classified as carnivorous dinosaurs that are able to walk on two legs with hollow, thin-walled bones and usually small forelimbs – the tyrannosaurus is a famous example.
The formal identification of the fossils was led by Monash University PhD candidate Jake Kotevski and the Museums Victoria Research Institute
It shows that Victoria's ancient ecosystem was dominated by large powerful megaraptorids (6–7 metres long) alongside smaller carcharodontosaurs (2–4 metres long) and agile, metre-long unenlagiines, or 'southern raptors'.
The discovery marks the first evidence of carcharodontosaurs in Australia's dinosaur record and is significant for contribution to the global theropod fossil record.
'The discovery of carcharodontosaurs in Australia is groundbreaking,' Mr Kotevski said.
'It's fascinating to see how Victoria's predator hierarchy diverged from South America, where carcharodontosaurs reached Tyrannosaurus rex-like sizes up to 13 metres, towering over megaraptorids. Here, the roles were reversed, highlighting the uniqueness of Australia's Cretaceous ecosystem.'
Two of the newly-described fossils represent the oldest known megaraptorids globally.
'Museum collections are crucial to advancing our understanding of prehistoric life', vertebrate palaeontology collection manager at Museums Victoria Research Institute Tim Ziegler said. 'Specimens preserved in the State Collection for decades – unidentifiable until now – are providing new insights into the evolution of dinosaur ecosystems'.
The findings highlight Victoria's unique Cretaceous fauna and offer 'compelling evidence of faunal interchange' between Australia and South America through Antarctica during the Early Cretaceous,' senior curator at Museums Victoria Research Institute Dr Thomas Rich said.
Key fossil sites are still being surveyed by Mr Kotevski and the team as part of Monash's Dinosaur Dreaming project.
It has uncovered more than 10,000 fossil bones and teeth since the project began in 1994 – including at least seven different dinosaurs, three groups of mammals, birds, pterosaurs, plesiosaurs, turtles and fishes.

'Statistically, that shouldn't have happened': Something very weird occurred in the ocean after the dinosaur-killing asteroid hit
When you buy through links on our articles, Future and its syndication partners may earn a commission. About 66 million years ago — perhaps on a downright unlucky day in May — an asteroid smashed into our planet. The fallout was immediate and severe. Evidence shows that about 70% of species went extinct in a geological instant, and not just those famous dinosaurs that once stalked the land. Masters of the Mesozoic oceans were also wiped out, from mosasaurs — a group of aquatic reptiles topping the food chain — to exquisitely shelled squid relatives known as ammonites. Even groups that weathered the catastrophe, such as mammals, fishes and flowering plants, suffered severe population declines and species loss. Invertebrate life in the oceans didn't fare much better. But bubbling away on the seafloor was a stolid group of animals that has left a fantastic fossil record and continues to thrive today: bivalves — clams, cockles, mussels, oysters and more. What happened to these creatures during the extinction event and how they rebounded tells an important story, both about the past and the future of biodiversity. Marine bivalves lost around three-quarters of their species during this mass extinction, which marked the end of the Cretaceous Period. My colleagues and I — each of us paleobiologists studying biodiversity — expected that losing so many species would have severely cut down the variety of roles that bivalves play within their environments, what we call their "modes of life." But, as we explain in a study published in the journal Sciences Advances, that wasn't the case. In assessing the fossils of thousands of bivalve species, we found that at least one species from nearly all their modes of life, no matter how rare or specialized, squeaked through the extinction event. Statistically, that shouldn't have happened. Kill 70% of bivalve species, even at random, and some modes of life should disappear. Related: The 5 mass extinction events that shaped the history of Earth — and the 6th that's happening now Most bivalves happily burrow into the sand and mud, feeding on phytoplankton they strain from the water. But others have adopted chemosymbionts and photosymbionts — bacteria and algae that produce nutrients for the bivalves from chemicals or sunlight in exchange for housing. A few have even become carnivorous. Some groups, including the oysters, can lay down a tough cement that hardens underwater, and mussels hold onto rocks by spinning silken threads. We thought surely these more specialized modes of life would have been snuffed out by the effects of the asteroid's impact, including dust and debris likely blocking sunlight and disrupting a huge part of the bivalves' food chain: photosynthetic algae and bacteria. Instead, most persisted, although biodiversity was forever scrambled as a new ecological landscape emerged. Species that were once dominant struggled, while evolutionary newcomers rose in their place. The reasons some species survived and others didn't leave many questions to explore. Those that filtered phytoplankton from the water column suffered some of the highest species losses, but so did species that fed on organic scraps and didn't rely as much on the Sun's energy. Narrow geographic distributions and different metabolisms may have contributed to these extinction patterns. Life rebounded from each of the Big Five mass extinctions throughout Earth's history, eventually punching through past diversity highs. The rich fossil record and spectacular ecological diversity of bivalves gives us a terrific opportunity to study these rebounds to understand how ecosystems and global biodiversity rebuild in the wake of extinctions. The extinction caused by the asteroid strike knocked down some thriving modes of life and opened the door for others to dominate the new landscape. While many people lament the loss of the dinosaurs, we malacologists miss the rudists. These bizarrely shaped bivalves resembled giant ice cream cones, sometimes reaching more than 3 feet (1 meter) in size, and they dominated the shallow, tropical Mesozoic seas as massive aggregations of contorted individuals, similar to today's coral reefs. At least a few harbored photosymbiotic algae, which provided them with nutrients and spurred their growth, much like modern corals. Today, giant clams (Tridacna) and their relatives fill parts of these unique photosymbiotic lifestyles once occupied by the rudists, but they lack the rudists' astonishing species diversity. Mass extinctions clearly upend the status quo. Now, our ocean floors are dominated by clams burrowed into sand and mud, the quahogs, cockles and their relatives — a scene far different from that of the seafloor 66 million years ago. Ecological traits alone didn't fully predict extinction patterns, nor do they entirely explain the rebound. We also see that simply surviving a mass extinction didn't necessarily provide a leg up as species diversified within their old and sometimes new modes of life — and few of those new modes dominate the ecological landscape today. Like the rudists, trigoniid bivalves had lots of different species prior to the extinction event. These highly ornamented clams built parts of their shells with a super strong biomaterial called nacre — think iridescent pearls — and had fractally interlocking hinges holding their two valves together. But despite surviving the extinction, which should have placed them in a prime position to accumulate species again, their diversification sputtered. Other types of bivalves that made a living in the same way proliferated instead, relegating this once mighty and global group to a handful of species now found only off the coast of Australia. These unexpected patterns of extinction and survival may offer lessons for the future. The fossil record shows us that biodiversity has definite breaking points, usually during a perfect storm of climatic and environmental upheaval. It's not just that species are lost, but the ecological landscape is overturned. Many scientists believe the current biodiversity crisis may cascade into a sixth mass extinction, this one driven by human activities that are changing ecosystems and the global climate. Corals, whose reefs are home to nearly a quarter of known marine species, have faced mass bleaching events as warming ocean water puts their future at risk. Acidification as the oceans absorb more carbon dioxide can also weaken the shells of organisms crucial to the ocean food web. Findings like ours suggest that, in the future, the rebound from extinction events will likely result in very different mixes of species and their modes of life in the oceans. And the result may not align with human needs if species providing the bulk of ecosystem services are driven genetically or functionally extinct. RELATED STORIES —Are we in a 6th mass extinction? —After the 'Great Dying,' life on Earth took millions of years to recover. Now, scientists know why. —Refuge from the worst mass extinction in Earth's history discovered fossilized in China The global oceans and their inhabitants are complex, and, as our team's latest research shows, it is difficult to predict the trajectory of biodiversity as it rebounds — even when extinction pressures are reduced. Billions of people depend on the ocean for food. As the history recorded by the world's bivalves shows, the upending of the pecking order — the number of species in each mode of life — won't necessarily settle into an arrangement that can feed as many people the next time around.

Experimental cholesterol pill cuts heart attack risk with 'convenient' once-daily dose
A new daily pill could provide an easier, more convenient way to lower cholesterol and reduce heart attack and stroke risk. The experimental medication, called Obicetrapib, underwent a Phase 3 clinical trial at Monash University in Australia. The trial included more than 2,500 people averaging 65 years of age. All had either been diagnosed with heart disease or had genetically high cholesterol, according to a university press release. All participants were receiving "maximum tolerated doses" of cholesterol-lowering therapy. One group received Obicetrapib and another group took a placebo, while still maintaining their existing cholesterol drugs. After 12 weeks, the participants taking the new drug showed a 32.6% reduction in LDL cholesterol and a 33.5% drop in lipoprotein(a) [Lp(a)], the release stated. The findings were presented last month at the European Atherosclerosis Society Congress in the U.K. and were also published in The New England Journal of Medicine. "We know that many people at high risk of heart attack or stroke don't get their cholesterol levels low enough, even on the best available treatments," said study lead Professor Stephen Nicholls, director of Monash University's Victorian Heart Institute and Monash Health's Victorian Heart Hospital, in the release. "We know that many people at high risk of heart attack or stroke don't get their cholesterol levels low enough, even on the best available treatments." "Obicetrapib offers a promising new option — not only did it lower LDL cholesterol by over 30%, but we also saw a reduction in Lp(a), which is much harder to treat and has been linked to increased heart disease risk." Low-density lipoprotein (LDL), which is sometimes called "bad cholesterol," is associated with negative health effects when present in high amounts. LDL can build up in the blood vessels and increase heart attack and stroke risk, the researchers cautioned. Lipoprotein(a), or Lp(a), is a protein that is known to greatly increase the chances of a heart attack when it's present in high levels in the blood. Unlike LDL, Lp(a) is an inherited risk factor that can't be modified with healthy behaviors or medications. Obicetrapib was found to be "well-tolerated" by the participants, the researchers noted. "This could be a valuable tool in the fight against heart disease," Nicholls added. "It's convenient, it's effective, and it may help close the gap for patients who've run out of options." The study — which was funded by NewAmsterdam Pharma, a developer of Obicetrapib that is based in the Netherlands — did have some limitations, the researchers noted. For example, the participants were not chosen based on high Lp(a), which means the study did not determine how the drug impacted those with elevated levels of the protein. Additionally, the study assessed changes in LDL levels, but did not measure actual heart attack or stroke outcomes.

Inside the battle to control the world's supply of rare earths
Back in 2009, Jim Kennedy, a consultant and entrepreneur of rare earths — a group of 17 metallic elements, including 15 lanthanides, crucial for modern technology — met with a top official at the Pentagon to discuss the future of these precious minerals. 'He was almost indifferent to the issue,' Kennedy tells The Post. 'His dispassion was staggering. It was one of the most disappointing meetings in my life.' Sixteen years later, that indifference has widely disappeared. Rare earths — used for everything from smartphones, electric cars and airplane engines to medical equipment, wind turbines and military applications like missiles and fighter jets — have become one of the most in-demand and politically contested industries in the world. 10 A miner carrying a heavy bag of rare earth-filled mud in China, which controls many of the most crucial rare earth elements now required for the sophisticated technology that powers everything from cellphones to fighter jets. REUTERS Rare earths 'enjoy an unusual level of bipartisan political support because they are vital both to economic development and national security,' says Melissa Sanderson, a former president and current board director at American Rare Earths, an Australian company focused on developing rare earth projects, including one in Wyoming. Rare earths aren't just a big part of modern technology; they're in many ways the most critical components. They're used as heat-absorbing agents in wind turbine motors, as strengthening and anti-glare agents in iPhones and fighter jets and as clarifying agents in MRIs. They're also almost completely controlled by China. Between 2020 and 2023, 70% of our rare earth imports came from China, according to Statista. That number jumped to 80% last year. And the US is 100% reliant on China imports of Yttrium, a rare earth metal used in everything from cellphones to TVs to radiation therapy used to treat liver cancer. 10 Rare earths 'enjoy an unusual level of bipartisan political support because they are vital both to economic development and national security,' says Melissa Sanderson, a former president and current board director at American Rare Earths. China has been fickle about granting export licenses for rare earths, although their grip has shown recent signs of weakening. President Trump had a lengthy (and rare) phone call with Chinese President Xi Jinping on June 5 and in a social media post after the call, Trump wrote 'there should no longer be any questions respecting the complexity of Rare Earth products.' The next day, China granted temporary export licenses to rare-earth suppliers of the top three US automakers. The irony is that for much of the mid-20th century, the US was a global leader of rare earth elements. But 'demand was exponentially lower at the time,' says Sanderson. 'Therefore, the output from our sole producer — Mountain Pass Materials, known as MP Materials now — was sufficient to satisfy a large percentage of then-existing demand.' The Las Vegas-Nevada-based company still operates the only rare earth mine and processing facility in the United States. 10 President Trump and President Zelensky meet in the Oval Office in February. Soon after this meeting a deal was made for Ukraine to supply vital rare earths to the United States. AFP via Getty Images America's rare earths lead came to an end in 1980, brought on by changes to US regulations. Because processing rare earth minerals involves the separation and removal of uranium and thorium, it can lead to radioactive waste and other contaminants. 'The US was concerned about the environmental impact, since particularly with the technology of the time, there were significant impacts to air, water and even ground quality that would not have met US standards,' says Sanderson. It wasn't the same story in China, who were more willing to accept the dangerous pollutants 'as a price for achieving its market dominance,' she says. China's monopoly of rare earths doesn't just give them an economic advantage. 'China has been 'weaponizing' its market hegemony for many years, in increasingly sophisticated and legal ways,' says Sanderson. 10 Pres. Trump with Chinese leader Xi Jinping. Having conceded its lead on rare earth mining, the US is playing a serious game of catch-up with the Chinese. REUTERS The country first flexed their power in 2010, blocking rare earth exports to Japan, a major producer of permanent metal magnets. 'That decision was overturned by the World Trade Organization, so China does not exert its control as overtly now,' says Sanderson. But in the current trade tussle with the US, 'China has identified seven crucial elements under its export control regime which it will not sell to the US,' says Sanderson. 'Due to concerns that while suitable for civilian economic use, they could also be used for military purposes.' While President Trump's tariffs are often blamed for exacerbating the tensions, Kennedy, who serves as president of ThREE Consulting, a rare earths consultancy, says the tariffs are actually 'forcing China to reveal the magnitude of this threat. Absent Trump's tariffs, China would never have shown its hand until it was too late.' 10 The US is 100% reliant on China imports of Yttrium, a rare earth metal used in everything from cellphones to TVs to radiation therapy used to treat liver cancer. REUTERS Just how bad could it get? Kennedy believes that if left unchecked, and China was allowed to continue their embargo without consequences, 'the non-Chinese world would need to shut down and re-engineer most everything that comes off an assembly line,' says Kennedy. 'This is not an overstatement.' The stand-off with China may be at the forefront, but it's not the only way Trump is maneuvering to protect the nation from rare earth depletion. Greenland contains (by some estimates) about a quarter of the world's rare earth minerals, and Trump has suggested that the US could annex the autonomous territory in Denmark. 10 A chunk of Ytrium, once of the most important rare earth elements. Phil Degginger/imageBROKER/Shutterstock The US also recently inked a landmark deal with Ukraine, which has approximately 5% of the total global mineral reserves. Although Trump declared in February that Ukraine would be providing 'the equivalent of like $500 billion worth of rare earth [minerals],' the exact amount wasn't specified in the deal, other than that the US and Ukraine would be splitting profits 50/50. There have also been efforts to mine rare earths from an entirely new source — the bottom of the Pacific Ocean. 10 Consultant Jim Kennedy was one of the first industry insiders to raise the alarm around the rarity — and potential global conflict — surrounding rare earths. It's called the 'Clarion Clipperton Zone,' a remote area of the Pacific between Hawaii and Mexico, roughly half the size of the contiguous US. This seabed region is rich in polymetallic nodules, the rock-like formations that contain some of the most sought-after rare earths in the world. It's a veritable goldmine waiting to be unearthed. In fact, the US Geological Survey recently estimated that the Clarion Clipperton Zone contains more nickel, cobalt and manganese than all terrestrial reserves combined. The Metals Company, a Canadian firm with US investment ties, is already making strides to become the first to mine commercially in the region. They conducted a field test back in 2022, and the company is currently applying for 'exploration licenses and commercial recovery permits' from the US. There are legal hurdles that could slow down their ambitions. Despite a 1980 law passed by Congress to regulate seabed mining, the Clarion Clipperton Zone technically falls under the jurisdiction of the International Seabed Authority, which operates under the United Nations Convention on the Law of the Sea. Whether the ISA has exclusive authority over the region remains open to debate. 10 Gerard Barron, CEO of The Metals Company, has dismissed some of the concerns about potential environmental damage surrounding rare earth mining efforts. AFP via Getty Images There are also environmental concerns. Arlo Hemphill, a Senior Oceans Campaigner at Greenpeace, warns that any move to mine the Pacific 'would be an ecological disaster. Scientists have not even had a chance to fully explore and understand the wonders of the deep, but a greedy corporation wants to tear up this ecosystem and cause immense ecological damage.' Gerard Barron, CEO of The Metals Company, dismisses these concerns, pointing out during a recent interview that Indonesia regularly mines in biodiverse rainforest regions. 'For some reason,' he said during the interview, 'people think it's okay to go digging up rainforests to get the metals underneath them, yet we're debating whether we should be going to pick up these rocks that sit on the abyssal plain?' (Barron did not respond to the Post's request for comment.) There are other options, but many are just as controversial. Sanderson believes the key will come down to strengthening our relationship with allies like Canada and Australia. 'They have significant natural resources and experienced and large mining companies,' she says. 'Cooperation with these countries is vital for filling the knowledge gap. The US doesn't have nearly enough experienced chemical and process engineers, as just one example.' 10 Rare earths are also crucial components of military fighter jets. Soonthorn – It took half a century for China to achieve its market position, she says, and the US needs an integrated supply chain from mine to magnet, but we're essentially starting from scratch. The US also needs to reform its mining regulatory system, which has a dysfunctional permitting process and some of the longest lead times for new mine production in the world. 'On average, companies wait anywhere from eight to fifteen years from when a deposit is initially determined to be economically interesting to when production can start,' says Sanderson, 'and some have waited significantly longer than that.' New mining projects are also frequently litigated, 'multiple times from multiple angles,' says Sanderson, which can add even more years to the wait time. With the return on investment horizon so long and the prospects so uncertain, many companies 'have difficulty attracting the investment necessary to support the high costs of building a mine,' she says. 10 Miners of rare earths such as these in China are increasingly at the forefront of the global race to control many of the elements that will determine our technological future. REUTERS Kennedy, however, is hopeful for the future. His company, Caldera Holding LLC, is collaborating with federal labs to refashion a former iron ore mine in Missouri to focus on rare earth minerals. He believes his mine is the only one that can provide 'geopolitically significant quantities' of rare earths.' But the ball, says Kennedy, is very much in Trump's court. His trade war has caused uncertainty, but the president's actions 'strongly suggest that delinking from China is real. This can be helpful, but follow-through is critical.' It's now up to the Trump administration to provide low-cost loans, grants and production tax credits to US-based mining companies that have (at least until now) faced almost insurmountable obstacles. 'Failure to support integrated projects,' says Kennedy, 'will result in many slow-motion train wrecks.'
