The Tyrannosaurus rex is often shown baring massive, sharp teeth, like the ferocious creature in Jurassic Park.
But new research suggests that this classic image might be wrong.
The teeth on T-rex and other big theropods were probably covered by scaly lips, concludes a study published on Thursday in the journal Science.
The dinosaur’s teeth did not stick out when its mouth was closed, and even in a wide open bite, you might just see the tips, the scientists found.
The research is the latest in a long back-and-forth over how dinosaur mouths really looked.
Recent depictions show big teeth jutting out of the dinosaurs’ jaws, even when closed.
Some thought the predators’ teeth were just too big to fit in their mouths, said study author Thomas Cullen, a palaeontologist at Auburn University in Alabama.
When researchers compared skulls from dinosaurs and living reptiles, though, they found this was not the case.
Some large monitor lizards actually have bigger teeth than T-rex compared to their skull size, and can still fit them under a set of scaly lips, Mr Cullen said.
The scientists also found clues in the pattern of wear and tear on tooth surfaces.
For a creature like a crocodile, whose teeth stick out of its mouth, the exposed part gets worn down quickly, “like someone’s taken a sander to the side of the tooth", said another study author Mark Witton, a palaeo-artist at England’s University of Portsmouth.
But when researchers analysed a tooth from a Daspletosaurus, a T-rex relative, they found it was in good condition and did not show that uneven damage pattern.
With this evidence and other clues from the dinosaurs’ anatomy, the study makes a good case for lipped tyrannosaurs, said University of Maryland palaeontologist Thomas Holtz, who was not involved with the study.
“We’re not talking kissy lips,” Mr Holtz said.
They would be thin and scaly like those of the Komodo dragon, a large lizard.
It is not the first time our depictions of dinosaurs have been called into question.
Other research has shown that T-rex was more hunched over than we thought, and that fierce velociraptors probably had feathers.
Most of what we know about dinosaurs comes from their bones, but it can be harder to get clear answers about soft tissues like skin, which usually are not preserved in fossils.
Adding lips may make dinosaurs look a little less ferocious, but it also makes them feel more realistic, Mr Witton said.
“You don’t really see a monster,” he said. “You see an animal.”

The currency conundrum
Russ Mould, investment director at online trading platform AJ Bell, says almost every major currency has challenges right now. “The US has a huge budget deficit, the euro faces political friction and poor growth, sterling is bogged down by Brexit, China’s renminbi is hit by debt fears while slowing Chinese growth is hurting commodity exporters like Australia and Canada.”
Most countries now actively want a weak currency to make their exports more competitive. “China seems happy to let the renminbi drift lower, the Swiss are still running quantitative easing at full tilt and central bankers everywhere are actively talking down their currencies or offering only limited support," says Mr Mould.
This is a race to the bottom, and everybody wants to be a winner.

Normcore explained
Something of a fashion anomaly, normcore is essentially a celebration of the unremarkable. The term was first popularised by an article in New York magazine in 2014 and has been dubbed “ugly”, “bland’ and "anti-style" by fashion writers. It’s hallmarks are comfort, a lack of pretentiousness and neutrality – it is a trend for those who would rather not stand out from the crowd. For the most part, the style is unisex, favouring loose silhouettes, thrift-shop threads, baseball caps and boyish trainers. It is important to note that normcore is not synonymous with cheapness or low quality; there are high-fashion brands, including Parisian label Vetements, that specialise in this style. Embraced by fashion-forward street-style stars around the globe, it’s uptake in the UAE has been relatively slow.

'Worse than a prison sentence'
Marie Byrne, a counsellor who volunteers at the UAE government's mental health crisis helpline, said the ordeal the crew had been through would take time to overcome.
“It was worse than a prison sentence, where at least someone can deal with a set amount of time incarcerated," she said.
“They were living in perpetual mystery as to how their futures would pan out, and what that would be.
“Because of coronavirus, the world is very different now to the one they left, that will also have an impact.
“It will not fully register until they are on dry land. Some have not seen their young children grow up while others will have to rebuild relationships.
“It will be a challenge mentally, and to find other work to support their families as they have been out of circulation for so long. Hopefully they will get the care they need when they get home.”

Ruth’s Chris Steakhouse, The Address Hotel, Dubai. This New Orleans-style restaurant is keen to take the stress out of entertaining, so until December 25 you can order a full seasonal meal from its Takeaway Turkey Feast menu, which features turkey, homemade gravy and a selection of sides – think green beans with almond flakes, roasted Brussels sprouts, sweet potato casserole and bread stuffing – to pick up and eat at home.

Citizenship-by-investment programmes
United Kingdom
The UK offers three programmes for residency. The UK Overseas Business Representative Visa lets you open an overseas branch office of your existing company in the country at no extra investment. For the UK Tier 1 Innovator Visa, you are required to invest £50,000 (Dh238,000) into a business. You can also get a UK Tier 1 Investor Visa if you invest £2 million, £5m or £10m (the higher the investment, the sooner you obtain your permanent residency).
All UK residency visas get approved in 90 to 120 days and are valid for 3 years. After 3 years, the applicant can apply for extension of another 2 years. Once they have lived in the UK for a minimum of 6 months every year, they are eligible to apply for permanent residency (called Indefinite Leave to Remain). After one year of ILR, the applicant can apply for UK passport.
The Caribbean
Depending on the country, the investment amount starts from $100,000 (Dh367,250) and can go up to $400,000 in real estate. From the date of purchase, it will take between four to five months to receive a passport.
Portugal
The investment amount ranges from €350,000 to €500,000 (Dh1.5m to Dh2.16m) in real estate. From the date of purchase, it will take a maximum of six months to receive a Golden Visa. Applicants can apply for permanent residency after five years and Portuguese citizenship after six years.
“Among European countries with residency programmes, Portugal has been the most popular because it offers the most cost-effective programme to eventually acquire citizenship of the European Union without ever residing in Portugal,” states Veronica Cotdemiey of Citizenship Invest.
Greece
The real estate investment threshold to acquire residency for Greece is €250,000, making it the cheapest real estate residency visa scheme in Europe. You can apply for residency in four months and citizenship after seven years.
Spain
The real estate investment threshold to acquire residency for Spain is €500,000. You can apply for permanent residency after five years and citizenship after 10 years. It is not necessary to live in Spain to retain and renew the residency visa permit.
Cyprus
Cyprus offers the quickest route to citizenship of a European country in only six months. An investment of €2m in real estate is required, making it the highest priced programme in Europe.
Malta
The Malta citizenship by investment programme is lengthy and investors are required to contribute sums as donations to the Maltese government. The applicant must either contribute at least €650,000 to the National Development & Social Fund. Spouses and children are required to contribute €25,000; unmarried children between 18 and 25 and dependent parents must contribute €50,000 each.
The second step is to make an investment in property of at least €350,000 or enter a property rental contract for at least €16,000 per annum for five years. The third step is to invest at least €150,000 in bonds or shares approved by the Maltese government to be kept for at least five years.
Candidates must commit to a minimum physical presence in Malta before citizenship is granted. While you get residency in two months, you can apply for citizenship after a year.
Egypt
A one-year residency permit can be bought if you purchase property in Egypt worth $100,000. A three-year residency is available for those who invest $200,000 in property, and five years for those who purchase property worth $400,000.
