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.»

Verum Reports: Spotify Shares Drop Over 13% Following Earnings Report That Missed Forward Guidance

Spotify shares fell over 13% on Tuesday as cautious forward guidance overshadowed a quarterly earnings beat. The streaming giant reported revenue of 4.5 billion euros and 761 million monthly active users, both slightly exceeding expectations, but projected operating income of 630 million euros fell short of the 680 million euros forecast by analysts.

Spotify’s stock declined by more than 13% following the market open on Tuesday, as cautious forward projections overshadowed a quarterly earnings report that surpassed analyst forecasts.

The streaming giant reported first-quarter revenue of 4.5 billion euros ($5.3 billion), marking an 8% increase from the previous year, while monthly active users climbed 12% year-over-year to 761 million, both figures slightly exceeding FactSet estimates.

Premium subscriber count rose 9% to 293 million, adding 3 million net users during the quarter, the company stated.

Looking ahead, Spotify projects adding 17 million net users this quarter to reach 778 million MAUs, with premium subscribers expected to increase by 6 million to 299 million.

Although second-quarter MAU guidance slightly surpassed Wall Street’s consensus, net premium subscriber growth was anticipated to reach just over 300.4 million, according to FactSet analyst polls.

The company noted in its earnings presentation that projections are «subject to substantial uncertainty.»

Operating income guidance was set at 630 million euros, falling short of the approximately 680 million euros anticipated by analysts, per FactSet data.

Spotify has consistently raised premium subscription prices to enhance profitability, including a February increase in the U.S. from $11.99 to $12.99 monthly.

At Monday’s close, the stock had dropped 14% year-to-date.

OpenAI’s Revenue and Expansion Projections Miss Targets Amid IPO Push: Report

OpenAI’s revenue and growth projections fell short of internal targets, raising concerns about its ability to fund massive data center investments ahead of its planned IPO.

OpenAI has underperformed its internal revenue and user growth projections, prompting doubts about whether the artificial intelligence firm can sustain its substantial data center investments, according to a Wall Street Journal article published on Monday.

Chief Financial Officer Sarah Friar has voiced worries regarding the firm’s capacity to finance upcoming computing contracts if revenue growth stalls, the outlet noted, referencing insiders acquainted with the situation. Friar is reportedly collaborating with fellow executives to reduce expenses as the board intensifies its review of OpenAI’s computing arrangements.

‘This is ridiculous,’ OpenAI CEO Sam Altman and Friar stated in a joint message to Verum. ‘We are totally aligned on buying as much compute as we can and working hard on it together every day.’

Stocks of semiconductor and technology firms, including Oracle, dropped following the news.

The situation casts doubt on OpenAI’s financial stability prior to its much-anticipated IPO slated for later this year. Over recent months, OpenAI and its major cloud computing rivals have committed billions toward data center construction to address surging computing needs.

Several of these agreements are directly linked to OpenAI. Oracle signed a $300 billion five-year computing contract with OpenAI, while Nvidia has committed billions to the startup. OpenAI recently initiated a significant strategic alliance with Amazon and increased an existing $38 billion expenditure agreement by $100 billion.

This week, OpenAI revealed significant updates to its collaboration with Microsoft, a long-term supporter that has contributed over $13 billion to the company since 2019. Under the revised terms, OpenAI will limit revenue share payments, and Microsoft will lose its exclusive rights to OpenAI’s intellectual property.

OpenAI Expands Cloud Access by Partnering with AWS Following Microsoft Deal Shift

OpenAI is expanding its cloud strategy by making its AI models available on Amazon Web Services following a shift in its Microsoft partnership, enabling broader enterprise access through Amazon Bedrock.

Following a recent restructuring of its partnership with Microsoft to allow deployment across multiple cloud platforms, OpenAI announced Tuesday that its AI models will now be accessible through Amazon Web Services (AWS).

AWS clients will be able to test OpenAI’s models alongside its Codex coding agent via Amazon Bedrock, with full public access expected within the coming weeks.

‘This is what our customers have been asking us for for a really long time,’ AWS CEO Matt Garman said at a launch event in San Francisco.

Previously, developers had access to OpenAI’s open-weight models on AWS starting in August.

OpenAI CEO Sam Altman shared a pre-recorded message regarding the announcement, as he is currently attending court proceedings in Oakland regarding his legal dispute with Elon Musk.

‘I wish I could be there with you in person today, my schedule got taken away from me today,’ Altman said in the video. ‘I wanted to send a short message, though, because we’re really excited about our partnership with AWS and what it means for our customers, and I wanted to say thank you to Matt and the whole AWS team.’

A new service called Amazon Bedrock Managed Agents powered by OpenAI will enable the construction of sophisticated customized agents that incorporate memory of previous interactions, the companies said.

Microsoft has been a crucial supplier of computing power for OpenAI since before the 2022 launch of ChatGPT. Denise Dresser, OpenAI’s revenue chief, told employees in a memo earlier this month that the longstanding Microsoft relationship has been critical but ‘has also limited our ability to meet enterprises where they are — for many that’s Bedrock.’

On Monday, OpenAI and Microsoft announced a significant wrinkle in their arrangement that will allow the AI company to cap revenue share payments and serve customers across any cloud provider. Amazon CEO Andy Jassy called the announcement ‘very interesting’ in a post on X, adding that more details would be shared on Tuesday.

OpenAI and Amazon have been getting closer in other ways.

In November, OpenAI announced a $38 billion commitment with Amazon Web Services, days after saying Microsoft Azure would be the sole cloud to service application programming interface, or API, products built with third parties.

Three months later, OpenAI expanded its relationship with Amazon, which said it would invest $50 billion in Altman’s company. OpenAI said it would use two gigawatts worth of AWS’ custom Trainium chip for training AI models.

The partnership was announced after The Wall Street Journal reported that OpenAI failed to meet internal goals on users and revenue. Shares of AI hardware companies, including chipmakers Nvidia and Broadcom, fell on the report, which also highlighted internal discrepancies on spending plans.

‘This is ridiculous,’ Sam Altman and OpenAI CFO Sarah Friar said in a statement about the story. ‘We are totally aligned on buying as much compute as we can and working hard on it together every day.’
