BERN, Switzerland (AP) — Nearly 300 Tyrannosaurus rex bones that were dug up from three sites in the United States and assembled into a single skeleton sold Tuesday at an auction in Switzerland for 4.8 million francs ($5.3 million), below the expected price.

Crafted into an open-mouth pose, the T. rex skeleton measuring 11.6 meters long (38 feet long) and 3.9 meters high (12.8 feet) high came in under the anticipated range of 5 million to 8 million francs when it went under the hammer at the Koller auction house in Zurich.

Koller had said Tuesday’s sale would be the first time such a T. rex skeleton would go up for auction in Europe. The composite skeleton, featuring 293 bones, was a showpiece of an auction that featured some 70 lots, and the skull was set up next to the auctioneer’s podium throughout.

“It could be that it was a composite — that could be why the purists didn’t go for it,” Karl Green, the auction house’s marketing director, said by phone. “It’s a fair price for the dino. I hope it’s going to be shown somewhere in public.”

Green did not identify the buyer, but said it was a “European private collector.” Including the “buyer’s premium” and fees, the sale came to 5.5 million Swiss francs (about $6.1 million), Koller said.

Promoters said the composite T. rex, dubbed “Trinity,” was built from specimens retrieved from three sites in the Hell Creek and Lance Creek formations of Montana and Wyoming between 2008 and 2013.

Koller said “original bone material” comprised more than half of the restored skeleton. The auction house said the skull was particularly rare and also remarkably well-preserved.

“When dinosaurs died in the Jurassic or Cretaceous periods, they often lost their heads during deposition (of the remains into rocks). In fact, most dinosaurs are found without their skulls,” said Nils Knoetschke, a scientific adviser who was quoted in the auction catalog. “But here we have truly original Tyrannosaurus skull bones that all originate from the same specimen.”

T. rex roamed the Earth between 65 million and 67 million years ago. A study published two years ago in the journal Science estimated that about 2.5 billion of the dinosaurs ever lived. Hollywood movies such as the blockbuster “Jurassic Park” franchise have added to the public fascination with the carnivorous creature.

The two areas the bones for Trinity came from were also the source of other T. rex skeletons that were auctioned off, according to Koller: Chicago’s Field Museum of Natural History bought “Sue” for $8.4 million over a quarter-century ago, and “Stan” sold for nearly $32 million three years ago.

Two years ago, a triceratops skeleton that the Guinness World Records declared as the world’s biggest, known as “Big John,” was sold for 6.6 million euros ($7.2 million) to a private collector at a Paris auction.

DALLAS (AP) — Southwest Airlines planes were briefly grounded nationwide Tuesday for what the airline called an intermittent technology issue, leading to more than 2,200 delayed flights just four months after the carrier suffered a much bigger meltdown over the Christmas travel rush.

The hold on departures was lifted by mid-morning Eastern time, according to Southwest and the Federal Aviation Administration, but not before traffic at airports from Denver to New York City backed up.

“Southwest has resumed operations after temporarily pausing flight activity this morning to work through data connection issues resulting from a firewall failure,” the Dallas-based airline said in a prepared statement. “Early this morning, a vendor-supplied firewall went down and connection to some operational data was unexpectedly lost.”

Southwest urged customers to check on their flight status “and explore self-service options” for travel as the airline worked on restoring its operation.

By late afternoon on the East Coast, more than half of all Southwest flights were delayed, and the airline accounted for half of all delays nationwide. On the positive side, Southwest had only about a dozen flights canceled, roughly in line with other major airlines, according to FlightAware.

Transportation Secretary Pete Buttigieg retweeted an FAA post about the ground stop, adding, “We are here to ensure passengers have strong protections when airline failures like this affect their plans.” He referred travelers to a Transportation Department checklist of passenger rights, and his press secretary noted that “no other airlines experienced disruptions.”

Tuesday’s delays added to the picture of an airline that has struggled more than most with technology issues.

“It was a 17-minute ground stop. This will have no long-lasting affect on Southwest’s reputation,” said Henry Harteveldt, a travel analyst with Atmosphere Research Group. “What matters now for Southwest is getting to the cause and doing all it can to ensure incidents like this don’t occur again.”

Rob Britton, a former American Airlines executive who teaches crisis management at Georgetown University, said the damage from Tuesday’s incident will be minor but will add to the erosion of Southwest’s image. He said Southwest has underinvested in technology while growing rapidly, and it suffers from an “insular culture” that “keeps them from looking outside for solutions.”

In December, Southwest canceled nearly 17,000 flights in a 10-day stretch around Christmas — wrecking holiday travel plans for well over 2 million people — when a winter storm shut down its operations in Denver and Chicago and the airline’s system for rescheduling pilots and flight attendants was overwhelmed.

Those cancellations cost the airline more than $1 billion and led to an ongoing Transportation Department investigation and a congressional hearing during which lawmakers complained that Southwest provided little or no help to stranded travelers.

Sen. Maria Cantwell, D-Wash., who led that hearing, said Tuesday’s breakdown “is another demonstration that Southwest Airlines needs to upgrade their systems and stop the negative impacts to individual travelers.”

The airline’s unions have said they warned management about problems with the crew-scheduling system after a previous meltdown in October 2021.

CEO Robert Jordan has embarked on a campaign to repair the airline’s damaged reputation. Southwest said last month it would add deicing equipment and increase staffing during winter weather that is cold enough to limit the amount of time that ground workers can stay outside.

Shares of Southwest Airlines Co. fell Tuesday nearly 1% while its closest rivals — American, Delta and United — all gained at least 1.5%.

TORONTO (AP) — The Canadian Broadcasting Corporation paused its use of Twitter on Monday after the social media platform owned by Elon Musk stamped CBC’s account with a label the public broadcaster says is intended to undermine its credibility.

Twitter labelled CBC/Radio-Canada “government-funded media” — the same label that prompted National Public Radio in the U.S. to similarly quit Twitter last Wednesday.

“Twitter can be a powerful tool for our journalists to communicate with Canadians, but it undermines the accuracy and professionalism of the work they do to allow our independence to be falsely described in this way,” CBC spokesman Leon Mar said in a statement announcing the change Monday afternoon.

“Consequently, we will be pausing our activity on our corporate Twitter account and all CBC and Radio-Canada news-related accounts,” the statement said.

CBC has sent a letter to Twitter asking the company to re-examine the designation. Musk later tweeted about it and changed it to “69 percent Government-funded media.”

CBC does not meet those criteria, Mar argued, because it is publicly funded through a parliamentary appropriation that is voted upon by all members of Parliament, and its editorial independence is protected in law in the Broadcasting Act.

The CBC’s board of directors determines how the funding it receives is spent. In 2021-22, the CBC received more than $1.2 billion Canadian (US$900 million) in government funding.

Opposition Conservative Party of Canada Pierre Poilievre had urged Twitter to label CBC. Canadian Prime Minister Justin Trudeau criticized Poilievre for what he called an “attack on a foundational Canadian institution.”

Twitter initially had labelled NPR’s main account as “state-affiliated media, ” a term also used to identify media outlets controlled or heavily influenced by authoritarian governments, such as Russia and China. Twitter later changed the label to “government-funded media,” but to NPR — which relies on the government for a tiny fraction of its funding — it’s still misleading.

Twitter earlier responded to a request for comment about why the label was applied and whether it would be removed or changed with an auto-generated email bearing a poop emoji.

Twitter, more than any of its rivals, has said its users come to it to keep track of current events. That made it an attractive place for news outlets to share their stories and reinforced Twitter’s moves to combat the spread of misinformation. But Musk has long expressed disdain for professional journalists and said he wants to elevate the views and expertise of the “average citizen.”

Musk has also abruptly suspended the accounts of individual journalists who wrote about Twitter late last year, claiming some were trying to reveal his location.

Twitter earlier in April removed the verification check mark on the main account of The New York Times, singling out the newspaper and disparaging its reporting after it said it would not pay Twitter for verification of its institutional accounts.

Twitter also used to tag journalists and other high-profile accounts with blue check marks to verify their identity and distinguish them from impostors. But Musk has derided the marks as an undeserved status symbol and plans to take them away from anyone not buying a premium subscription.
