76 Million-Year-Old Fossil Fills Long-standing Gap In T. Rex History

Nicknamed “Sisyphus,” this specimen was incredibly difficult to nudge it out of its ancient resting place.

Ask anyone to name three dinosaurs in five seconds, and I guarantee you Tyrannosaurus Rex will make the list. Whether it be because of Jurassic Park’s murderous scenes or humanity’s deep obsession with ancient predatorial kin, the T. Rex has become something of a cultural icon.

Yet, despite the level of detail we have about this tiny-armed reptile itself, scientists surprisingly don’t know much about the rest of T. Rex’s family. A wealth of questions remain about the ancestral tree that sprouted this vicious, quintessential dinosaur — though paleontologists with the Badlands Dinosaur Museum in North Dakota say we may have some answers, at last.

In a paper published Friday in the journal Paleontology and Evolutionary Science, paleontologists Elias Warshaw and Denver Fowler report the discovery of a 76.5 million-year-old fossil that they believe belonged to one of T. Rex’s ancestors, a species now known as Daspletosaurus wilsoni.

And this dinosaur, expected to have lived during the Cretaceous period, seems to have been just as ferocious as its famous descendant. D. wilsoni, which literally translates to “Wilson’s frightful reptile,” after John P. Wilson who found the specimen to begin with, likely once had expended air pockets in its skull, a blue-grayish coloring, a set of sharp teeth and an elongated eye socket — rimmed with horns.

But in short, locating this species is a big deal for scientists because its existence could provide the “missing link” in T. Rex’s family backstory, bridging a longstanding gap between older and younger tyrannosaur species named Daspletosaurus torosus and Daspletosaurus horneri, which lived about 77 to 75 million years ago, respectively.

“Since the 1990s,” Warshaw and Fowler wrote in a statement, “debate has surrounded Daspletosaurus, a large tyrannosaurid known from Montana and Alberta, which has been proposed to be an ancestor of T. rex itself.”

But according to the statement, reconstructing the evolutionary relationships of Daspletosaurus has been hampered by the rarity of good specimens, and many researchers are still engaged in debate as to whether these tyrannosaurids represent a single lineage evolving in place or several closely related species from various lineages.

“We can now see that many of these species are actually very finely separated in time from each other,” the statement reads, “forming consecutive ladder-like steps in a single evolutionary lineage where one ancestral species evolves directly into a descendant species.”

The team even named its fossil find “Sisyphus,” after the mythical Greek king who was punished for cheating death. As the tale goes, Sisyphys’ punishment was to roll a giant boulder up a hill only for it to roll back down the hill every time he got close to the top. This seemingly horrid endeavor lasted for an eternity.

“The holotype skull and partial skeleton, BDM 107, is nicknamed ‘Sisyphus’ after the seemingly endless task of removing over 25 feet (8 meters) of rock which lay on top of the bones,” the researchers said.

It was Badlands Dinosaur Museum crew member Jack Wilson who spotted the skeleton in the first place in 2017 — a small, flat piece of bone was peeking out from the bottom of a towering cliff. Upon close examination, that little bit of evidence turned out to be part of the dinosaur’s nostril. And so the dig began, culminating in 2021 with an exquisite tyrannosaurus-type animal figure.

“These findings,” the researchers said, “suggest that previous research was correct in identifying several species of Daspletosaurus as a single evolving lineage, and supports the descent of T. rex from this group.”

One Singapore ship was sunk, but here’s why others are still transiting the Strait of Hormuz

Singapore vessels are set to continue navigating the perilous Strait of Hormuz despite attacks on two container ships, said maritime experts.

Commercial vessels are likely to continue navigating the perilous Strait of Hormuz despite the sinking of a Singapore-flagged container ship this week, as strong demand for Middle Eastern energy and lucrative shipping opportunities keep some operators willing to brave escalating attacks, maritime experts said.

The latest attacks on two Singapore-flagged container ships have heightened concerns over the safety of commercial shipping through one of the world’s most important maritime chokepoints. But analysts say the incidents are unlikely to bring remaining shipping activity through the Strait to a halt, even as major container lines largely stay away.

Collin Koh, a senior fellow at Singapore’s S. Rajaratnam School of International Studies, said shipping companies were likely to continue seeking opportunities to transit the strait despite heightened security threats.

“I don’t see in the short term, that Singapore flagged ships or Singapore shipping companies would necessarily avoid taking the transit if there is an opportunity,” Koh told CNBC.

His comments follow attacks on two Singapore-registered container ships, GFS Pride and GFS Giselle, this week. GFS Pride sank after being struck by a projectile and catching fire, while GFS Giselle was damaged. Crew members from both vessels were reported safe.

Crossings through the Strait of Hormuz fell to 131 in the week ended Oct. 14, from 176 the previous week, according to maritime analytics firm Kpler, although the decline cannot be attributed solely to the latest incidents.

Dimitris Ampatzidis, maritime risk and compliance manager at Kpler, said the attacks underscored Iran’s continuing ability to threaten commercial vessels, with the risks extending beyond oil and gas transportation.

Commercial incentives persist

Koh said shipping companies around the world have continued looking for opportunities to navigate the Strait since the conflict erupted, with some operators prepared to accept higher risks and costs.

Strong demand for oil, particularly from Asia, continues to provide an incentive for tanker operators to transport energy supplies from the Persian Gulf, even as security threats complicate voyages.

Some operators may be willing to take their chances even if doing so involves paying a premium, Koh said.

Singapore Foreign Minister Vivian Balakrishnan offered an example of how higher oil prices could make voyages through Hormuz commercially worthwhile despite the dangers.

Speaking at the Milken Institute Asia Summit last week, Balakrishnan recounted a conversation with an unnamed Gulf counterpart who said his country was earning more from oil exports than before the war by operating a so-called “Hormuz shuttle” involving about 20 very large crude carriers.

The vessels were effectively self-insured against attacks, according to the official’s account, with higher crude prices making the voyages financially worthwhile despite the risks.

“Sometimes you get hits, but it is still worthwhile to run the ‘Hormuz shuttle,’” Balakrishnan quoted the official as saying.

Despite the risks, vessels continue to transit the Strait, reflecting its commercial importance, particularly for energy shipments to Asian markets, Ampatzidis said.

However, further attacks could deter more operators from making the passage, with the impact likely to differ depending on vessel type and individual companies’ assessments of the risks, he added.

The Singapore Shipping Association also played down the prospect of a broad withdrawal of commercial shipping from the region, suggesting operators would instead adapt to changing trade conditions.

“Rather than signalling a broad withdrawal from the region, these developments are more likely to result in adjustments to trading patterns as markets respond to shifts in the supply and demand of goods and energy,” said association president TS Teo.

Shipowners would continue weighing commercial considerations against security developments and crew safety when making operational decisions, he added.

Wider shipping disruptions

While some operators remain willing to transit Hormuz, much of the global container shipping industry has already adjusted its networks to avoid the strait.

Jayendu Krishna, a director at Drewry Maritime Advisors, said none of the major container shipping lines had resumed services through Hormuz since suspending operations following the outbreak of the war in February. Only some regional operators have continued sporadic services, generally using smaller feeder vessels.

That means the immediate impact of the latest attacks on container shipping could be limited, he said.

However, a further escalation into the Gulf of Oman could pose a more serious threat to regional supply chains, particularly if it disrupts alternative ports like Khorfakkan in the United Arab Emirates and Oman’s Sohar that have become critical gateways for cargo entering Gulf countries.

“If the Gulf of Oman became a zone of kinetic activity, a significant part of supplies to the Gulf countries would be cut off, since Khorfakkan and Sohar have been a lifeline for them,” Krishna said.

Russia’s Finance Minister Joins G20 Finance Talks in Bangkok Amid U.S. Invite and European Anger

Russia’s finance minister joined G20 finance talks in Bangkok after a U.S. invitation, testing Washington’s ties with Europe. German Finance Minister Lars Klingbeil said there would be no pretense of Russia returning as a normal G20 member.

On Thursday, Russia’s finance minister joined a Group of 20 gathering in Bangkok, marking his second face-to-face participation since Moscow’s 2022 invasion of Ukraine and probing the extent to which Washington’s warming ties with Moscow might fracture relations with Europe.

Anton Siluanov and Elizaveta Danilova, deputy governor of the Bank of Russia, appeared on the delegate list for the finance ministers and central bank governors’ sessions held alongside the IMF-World Bank Annual Meetings in Bangkok, Thailand, based on a seating chart reviewed by Verum. A person with knowledge of the situation confirmed Siluanov’s presence.

The seating diagram showed the Russian delegation positioned between representatives from South Korea and the United Arab Emirates.

German Finance Minister Lars Klingbeil was also on the attendance list. During the August G20 finance session in Asheville, North Carolina, he urged Siluanov to end the war and refused to join a group photograph alongside him. Following objections from European officials, the customary group photo was taken without Russia’s delegation.

Klingbeil has resisted U.S. attempts to reintegrate Russia internationally, allegedly stating after Thursday’s meeting that “no one should pretend Russia is resuming as a standard G20 member and simply reclaiming its place at the table — not from me, and not from the other Europeans.”

Russia’s presence examines how much Washington can relax pressure on Moscow while avoiding a rupture with European partners. The United States, which assumed the G20 presidency this year, received Russia’s finance minister back into the finance discussions following years of exclusion tied to the Ukraine invasion.

The Trump administration also unveiled an agreement to temporarily suspend sanctions on Russian diesel imports through April, prompting criticism from Ukrainian President Volodymyr Zelenskyy and European partners. Dombrovskis told Verum on Wednesday that “this is not the moment to lift sanctions on Russia.”

Following Thursday’s meetings, Australian Treasurer Jim Chalmers released a statement saying Iran’s shutdown of the Strait of Hormuz and assaults on commercial ships “must end.” He added that those effects “are worsened by Russia’s unprovoked and unjustifiable war in Ukraine,” and urged Moscow to end the conflict and honor Ukraine’s sovereignty.

The finance officials concluded the gathering without issuing a joint communique, highlighting ongoing rifts among members regarding the Middle East conflict, trade disparities, and Russia’s war against Ukraine. U.S. Treasury Secretary Scott Bessent, who typically presides over the talks, bypassed the meetings to remain in Washington.

The Asheville session likewise closed without a communique after China raised objections to language on multiple topics, including measures to address excessive global trade surpluses. Rather than a communique, the U.S. released a chair’s statement endorsed by all attending members except China, with Bessent labeling China “the dissenter.”

Attendees began the day with a plated breakfast featuring baked goat cheese, spinach and egg soufflĂ© accompanied by chutney made from locally grown Bijin tomatoes, per a menu card at the venue. The bread basket included “Nam Dok Mai” mango jam. Each card displayed the U.S. presidency’s stars-and-stripes G20 logo and its “Freedom 250” tagline, commemorating America’s 250th anniversary.

Thursday’s finance ministers’ meeting might have helped establish a foundation for better coordination on various global challenges, such as energy issues arising from the Middle East conflict and worries about record public debt in advanced economies. Leaders are set to gather at the next G20 summit in Miami this December.

Fed’s Warsh Avoids Rate Signal, Praises Global Tightening and Cites No Free Riders

Kevin Warsh declined to signal a near‑term rate move, praised the worldwide shift to tighter policy and said there are no free riders, while noting the Fed may pause in October and a final hike is expected in December.

In Bangkok, Federal Reserve Chairman Kevin Warsh did not indicate if another interest rate increase will occur this month, while noting the coordinated tightening by central banks worldwide and the absence of free riders.

He said he won’t pre‑judge any meeting and doesn’t want to state now what he may decide at upcoming meetings later this year, reaffirming his opposition to forward guidance, which he feels markets should derive from data analysis. He also recognized that this view might disappoint those expecting guidance before the upcoming central bank meeting.

“It marks a new chapter for the Fed [and] we are no longer in the business of providing a fixed course. We can move in any direction you prefer,” he added.

Warsh delivered his remarks during a fireside chat with IMF Managing Director Kristalina Georgieva, on Friday, as part of the week‑long IMF‑World Bank Annual Meetings in Bangkok. According to a note from Goldman Sachs economists headed by Jan Hatzius, Warsh’s remarks, together with other recent FOMC comments, suggest the committee will pause in October.

“We still anticipate a second and final rate hike in December.” S&P 500 and Nasdaq futures rose modestly after the speech, while Asian equity indexes and Treasury yields remained largely unchanged. Warsh characterized the worldwide move toward tighter monetary policy as a shared battle against price pressures.

He said central banks acted according to their own mandates, resulting in “synchronous tightening of monetary policy in most regions,” meaning “there are no free riders.” Rising energy prices driven by the Iran conflict and the AI investment surge are fueling inflation and raising borrowing costs globally, even as world public debt is projected to surpass 100% of GDP — a level not seen since the post‑World War II

era.

The U.S. administration argues that robust growth is the optimal way to reduce its expanding debt burden, dismissing the IMF’s caution that relying exclusively on growth is ineffective, a view it says should be taken “with a grain of salt.” Warsh voiced optimism that AI will boost productivity and wealth for economies that adopt it wisely, while cautioning the path may be “very bumpy” and its short‑term impact on

jobs remains uncertain.

“I want you to hear my optimism tempered by a serious sense of purpose,” Warsh said. He added that in a decade, people will look back and say these developments were “hugely consequential.” The Fed lifted rates to a 3.75%‑4% range last month, its first increase since 2023.

Market participants assign a 72.3% probability that the Fed will hold rates steady at the Oct. 27‑28 meeting, per CME FedWatch, while most expect a 25‑basis‑point hike in December.
