Lost and found at sea — Researchers look a dinosaur in its remarkably preserved face Washed out to sea, a giant beast and its armored skin were left in pristine condition.

Borealopelta markmitchelli found its way back into the sunlight in 2017, millions of years after it had died. This armored dinosaur is so magnificently preserved that we can see what it looked like in life. Almost the entire animalthe skin, the armor that coats its skin, the spikes along its side, most of its body and feet, even its facesurvived fossilization. It is, according to Dr. Donald Henderson, curator of dinosaurs at the Royal Tyrrell Museum, a one-in-a-billion find.

Beyond its remarkable preservation, this dinosaur is an important key to understanding aspects of Early Cretaceous ecology, and it shows how this species may have lived within its environment. Since its remains were discovered, scientists have studied its anatomy, its armor, and even what it ate in its last days, uncovering new and unexpected insight into an animal that went extinct approximately 100 million years ago. Down by the sea

Borealopelta is a nodosaur, a type of four-legged ankylosaur with a straight tail rather than a tail club. Its finding in 2011 in an ancient marine environment was a surprise, as the animal was terrestrial.

A land-based megaherbivore preserved in an ancient seabed is not as uncommon as one might think. A number of other ankylosaurs have been preserved in this manner, albeit not as well as Borealopelta. Scientists suspect its carcass may have been carried from a river to the sea in a flooding event; it may have bobbed at the surface upside-down for a few days before sinking into the ocean depths.

It would have been kept at the surface by whats referred to as “bloat-and-float,” as the buildup of postmortem gasses would keep it buoyant. Modeling done by Henderson indicates its heavy armor would have rolled it onto its back, a position he suspects may have prevented ocean predators from scavenging its carcass. Advertisement

Once the gasses that kept it floating were expelled, Borealopelta sank to the ocean floor, landing on its back. What’s a nodosaur?
Dr. Caleb Brown at the Royal Tyrrell Museum explains the somewhat confusing designation as follows: There are two families of armored dinosaurs: Ankylosauridae (those with tail clubs) and Nodosauridae (those with shoulder spines and no tail clubs).The group that includes both of these families is called the Ankylosauria. While the term nodosaur generally means an animal with the family Nodosauridae, the term ankylosaur could mean two different things: 1) an animal from the family Ankylosauridae (which would exclude Nodosauridae), or 2) the group Ankylosauria (which includes Nodosauridae).

It is correct to call Borealopelta an ankylosaur (which would mean Ankylosauria) or a nodosaur (which would mean Nodosauridae). You just cant call it an Ankylosaurid, Ankylosaurine, or Ankylosauridae (as these have specific meanings).

We can see it went in water deeper than 50 meters because it was preserved with a particular mineral called glauconite, which is a green phosphate mineral. And it only forms in cooler temperatures in water deeper than 50 meters, explained Dr. Henderson.

He also told Ars that this environment probably also discouraged scavenging, saying, It was probably a region where [long-necked] plesiosaurs and big fish didnt like to go. It was too cold and too dark, and [there was] nothing to eat. And there were very few trace fossils in the sediments around it. So there wasnt much in the way of worms and crustaceans and bivalves and things in there to further digest it. It was just a nice set of conditions in the seabed that had very low biological activity that led to that preservation. Unmet expectations

But none of this was known when the animal was discovered. Although it’s not entirely unusual to find dinosaur remains in marine environments, its also not very common. Henderson and Darren Tanke, also from the Royal Tyrrell Museum, walked onto the site fully anticipating that they would excavate an ancient marine reptile.

The two had consulted on fossil discoveries at other open-pit mines within the province. However, this was their first visit to Suncor, a mine in the northeast of Alberta, Canada. Everything about this mine is enormous. Massive machinery is constantly in motion, scooping out rock, sand, and gravel from surrounding cliffs, while other equipment clears it away, all with the goal of uncovering the deeper oil sands for fuel.

Its just unbelievable, the scale of the place, Dr. Henderson said. And it goes 24 hours a day, 365 days a year.

Despite the pace of operations, one particular shovel operator, Shawn Funk, happened to notice something after taking a big chunk out of the cliff. It was thanks to him and several people within Suncor that operations stopped in that area and the Royal Tyrrell was notified.

Surprise good news as government borrowing less than forecast

Surprise good news as government borrowing less than forecast

The government borrowed the least amount of money in three years last month, official figures showed, in a surprise bout of good news for Chancellor Rachel Reeves.

Not since July 2021, in the midst of the COVID-19 pandemic, was state borrowing so low, according to data from the Office for National Statistics (ONS).

Increases in tax and national insurance receipts meant public sector net borrowing was £1.1bn in July, meaning there was a £1.1bn gap between government spending and income.

That borrowing is less than half the figure (£2.6bn) expected by economists polled by the Reuters news agency, as self-assessed income tax was £600m higher than expected.

But borrowing was still £6bn higher in the first four months of the financial year, which started in April, than the same period in 2024.

Despite a £2.3bn drop in monthly borrowing when July 2025 is compared with July 2024, the state still spent more on the cost of that lending.

The amount of interest paid on government debt was £7.1bn, £200m more than a year earlier.

The cost of government borrowing has increased in recent months as the interest rate investors demand on loans issued to the UK (bonds) rose.

At the start of the week, the government’s long-term borrowing cost, as measured by the interest rate on 30-year bonds (known as the gilt yield), closed at the highest level since 1998.

What does it mean for the chancellor?

The monthly borrowing data is in line with the predictions made by independent forecasters, the Office for Budget Responsibility (OBR).

It may not be as rosy a picture, however, as research firm Capital Economics point out the cumulative budget deficit, rather than a monthly figure, is £5.7bn above the OBR’s forecast.

Are taxes going to rise?

This matters for the chancellor’s self-imposed fiscal rules, to bring down government debt and balance the budget by 2030, the firm said.

“The chancellor will probably need to raise taxes by £17bn to £27bn at the budget later this year,” Capital Economics’ UK economist Alex Kerr said.

Elevated self-assessment income tax receipts “may just reflect the timing of tax returns being recorded, and receipts in August may be weaker than expected”, he added.

Responding to the figures, Ms Reeves’s deputy, chief secretary to the Treasury, Darren Jones, said: “Far too much taxpayer money is spent on interest payments for the longstanding national debt.

“That’s why we’re driving down government borrowing over the course of the parliament – so working people don’t have to foot the bill and we can invest in better schools, hospitals, and services for working families.”

CNBC Daily Open: Tech sell-off? Investors could just be taking profit and enjoying the summer

If you have any U.S. technology stocks in your portfolio (and let’s face it, who doesn’t?), you might want to look away.

For the second day in a row, tech stocks dragged markets lower, with the Nasdaq Composite slipping 0.67%. Juggernauts such as Apple, Amazon and Alphabet were more meh-nificent than magnificent, falling more than 1%.

Palantir — the standout S&P 500 stock, having more than doubled so far this year — had its sixth consecutive day in the red and lost its place among a ranking of the 20 most valuable U.S. companies.

While Palantir’s slide was partly triggered by a report from short seller Andrew Left’s Citron Research, which called the company “detached from fundamentals and analysis,” there was no single trigger for the broader pullback.

Investors could have been spooked by OpenAI CEO Sam Altman’s caution about an AI bubble forming, although some analysts dispute that assertion. “In our view the tech bull cycle will be well intact at least for another 2-3 years,” said Wall Street tech bull Dan Ives.

Or it could be something benign, like traders locking in profits. “Tech stocks,” said Carol Schleif, chief market strategist at BMO Private Wealth, “have had an incredibly strong run – with some up over 80% since the early April lows.”

Summer, after all, is far from over. Some investors might have just wanted to cash out for another round of margaritas.

Red carpet for Putin, trade relief for China, penalties on India: Inside Trump’s peculiar policy playbook

U.S. President Donald Trump is pursuing an unusual strategy — courting Russian President Vladimir Putin, holding fire on Beijing, all the while turning the screws on India.

Despite India being one of the earliest nations to engage in negotiations with the Trump administration, there is still no sign of it sealing a deal with America. New Delhi is now also staring at a secondary tariff of 25% or a “penalty” for its purchases of Russian oil that is set to come into effect later this month.

How Trump’s Republicans are literally redrawing maps to help stay in power

How Trump's Republicans are literally redrawing maps to help stay in power

Legislators in Texas have approved new congressional maps designed to boost Donald Trump’s Republicans at next year’s midterm elections.

Known as redistricting, the state’s re-drawn map would shift conservative voters into districts currently held by Democrats, and combine other districts with a Democratic majority into one.

The process is not new, and is completely legal – unless it is ruled to be racially motivated – but typically occurs every 10 years after the US Census to account for population changes.

The push to redistrict early came from Mr Trump himself, who wants to bolster his chances of preserving the slim Republican majority in the House of Representatives at next year’s crucial midterms.

But by trying to re-draw the maps in the red state of Texas, Democrats have lined up their own counter redistricting effort in the blue state of California.

If more states decide to re-consider their maps, it has the potential to largely determine the outcome of the 2026 midterms, before a single vote is cast.

What’s happening in Texas?

Mr Trump first said he wanted politicians in Texas to redraw the state’s congressional district in July. The governor of Texas, Greg Abbott, followed up on the president’s demands, calling for a special session to vote on new maps.

“Please pass this map ASAP,” Mr Trump urged on his Truth Social platform on Monday. “Thank you, Texas!”

In an effort to try to make passing the vote as difficult as possible, Democrats fled the state for two weeks. Per parliamentary rules, if enough Democrats refuse to take part in the special session, the Texas House can’t meet.

On their return, each Democratic politician was assigned a police escort to ensure they attended the session.

Nicole Collier, who refused the police escort, stayed in the House for two nights, and was pictured with an eye mask and blanket trying to sleep at her desk.

Once the debate started, the doors to the chamber were locked and all members wanting to leave had to get a permission slip to do so.

After nearly eight hours, the legislation to formally change the map was passed 88-52 on Wednesday.

It now needs to be approved by the Texas Senate, where Republicans hold a majority, and then signed off by Mr Abbott, who has already committed to doing just that.

Why re-draw maps?

Republicans in Texas have openly said the rally to re-draw congressional maps is in the party’s interest.

Todd Hunter, the Republican who wrote the legislation formally creating the new map, told the House: “The underlying goal of this plan is straight forward: improve Republican political performance.”

He said the dispute is nothing more than a partisan fight, and made reference to the US Supreme Court having previously allowed politicians to redraw districts for partisan purposes.

Democrats hit back, arguing the disagreement was about more than partisanship.

“In a democracy, people choose their representatives,” representative Chris Turner said. “This bill flips that on its head and lets politicians in Washington, DC, choose their voters.”

Another Democrat, John H Bucy, blamed the president, saying: “This is Donald Trump’s map.

“It clearly and deliberately manufactures five more Republican seats in Congress because Trump himself knows that the voters are rejecting his agenda.”

How have Democrats responded?

The move by Republicans has triggered a tit-for-tat move by the Democrats, who are due to meet in California on Thursday to revise the state’s maps in order to gain five more seats.

To enact the same powers in California will prove harder, as state laws require an independent commission to take responsibility for redistricting – meaning it would need to be approved by voters in a special election.

In other blue states, rules are even tighter. For example, in New York, they cannot draw new maps until 2028, and even then, only with voter approval.

Despite the obstacles, California governor Gavin Newsom confirmed a redistricting election will take place in the state on 4 November, in order to “fight fire with fire”.

His plan has gained support from former president Barack Obama, who said it was necessary to “stave off” the Republicans’ move in Texas.

Could this affect the midterms?

The midterms in November next year will likely be on a knife edge.

Whatever the outcome, it could shape the remainder of Mr Trump’s second term in office. A Democrat majority would make it tougher for him to pass laws.

Currently, Republicans control the House of Representatives in Washington, 219-212 (excluding four open vacancies). A party needs 218 seats for a majority.

In the Senate, the Republicans hold a similarly slim majority of 53 to 45.

However, the incumbent president’s party typically loses seats in the midterms.

In the 2018 midterms, during Mr Trump’s first tenure as president, the Democrats took control of the House. Likewise, in 2022, when Joe Biden was president, the House swung back to the Republicans.

It’s important to note that 27 House seats will remain in states that are unlikely to redraw their maps, according to The New York Times.

In a bid to avoid a repeat of history, Mr Trump is pushing for redistricting in states beyond Texas. Top Republicans in states like Indiana, Missouri, and Florida continue to talk about tweaking their maps to create more Republican-controlled congressional seats.

While Ohio has to legally redraw, the timing of which could benefit the Republicans, and, by extension, Mr Trump.
