The fossil of a 170 million-year-old pterosaur, described as the world’s best-preserved skeleton of the prehistoric winged reptile, has been found on the Isle of Skye in Scotland, scientists said Tuesday.
The National Museum of Scotland said the fossil of the pterosaur, more popularly known as pterodactyls, is the largest of its kind ever discovered from the Jurassic period. The reptile had an estimated wingspan of more than 2.5 meters (8.2 feet), similar to that of an albatross, the museum said.
The fossil was discovered in 2017 by PhD student Amelia Penny during a field trip on the Isle of Skye in remote northwestern Scotland, when she spotted the pterosaur’s jaw protruding from rocks. It will now be added to the museum’s collection.
“Pterosaurs preserved in such quality are exceedingly rare and are usually reserved to select rock formations in Brazil and China. And yet, an enormous superbly preserved pterosaur emerged from a tidal platform in Scotland,” said Natalia Jagielska, a doctoral student at the University of Edinburgh who is the author of a new scientific paper describing the find.
Steve Brusatte, a professor of palaeontology at Edinburgh University, said the discovery was the best one found in Britain since the early 1800s, when celebrated fossil hunter Mary Anning uncovered many significant Jurassic fossils on the southern English coast.
He said the fossil had “feather light” bones, “as thin as sheets of paper,” and it took several days to cut it from rock using diamond-tipped saws as his team battled against encroaching tides.
It “tells us that pterosaurs got larger much earlier than we thought, long before the Cretaceous period when they were competing with birds, and that’s hugely significant,” Brusatte added.
The pterosaur has been given the Gaelic name Dearc sgiathanach, which translates as “winged reptile."
Pterosaurs were the first vertebrates to fly, some 50 million years before birds. They lived as far back as the Triassic period, about 230 million years ago. They were previously thought to have been much smaller during the Jurassic period.
Experts say that at some point next year, the pandemic will officially drop its pandemic status, becoming endemic. While this is a milestone to acknowledge, it does not mean we're free of infections, illnesses, and deaths. Dr. Rajeev Fernando, infectious disease specialist, Beth Israel Hospital and fellow, joins Cheddar News' Closing Bell to discuss.
Chicago-based Internist Dr. Vivek Cherian joined Wake Up With Cheddar to break down the unprecedented surge in U.S. COVID-19 as many prepare to celebrate the new year.
Dr. Soumi Eachempati, co-founder and CEO of Cleared4 and former professor of surgery and public health at Weill Cornell Medical College, joined Cheddar to breakdown what people should know about the recently FDA-approved emergency use of Merck and Pfizer's COVID-19 treatment pills. He noted that not only do people need to be aware of other medications they are taking that could cause adverse effects if coupled with COVID-19 pill treatments, he also talked about the intense in-take regiment. "The Merck pills are actually about 40 pills over five days. The Pfizer ones are three pills over five days, so people have to be prepared for that because it is a lot of pills you'll have to take to get full value from these drugs," Eachempati told Cheddar.
Twitter is exploding with a new meme after the CDC revised its Covid-19 guidelines, shortening the recommended isolation period to five days instead of 10 for when you test positive and are asymptomatic. The change came amid a skyrocketing surge of new cases is the U.S. due to the Omicron variant, drawing criticism from experts and Twitter --with users claiming the government agency is giving funny advise on a variety of issues. But what does the meme say about the public’s trust in the agency? Cheddar News speaks with political strategist Hastie Afkhami.
The list of questions should be getting shorter as we enter the pandemic's third year, but that isn't the case. There's another question to add to that list: is the U.S. doing enough to track the virus and its variants? Lawrence Gostin, faculty director of the O'Neill Institute for national and global health law at Georgetown University, joins Cheddar News.
As we prepare to ring in the new year, COVID cases are hitting an all-time high. Dr. Anthony Fauci has said the safest way to celebrate would be a small gathering with vaccinated family members only... far from the large, flashy parties from a few years ago. Dr. Christina Johns, senior medical advisor at PM Pediatrics, joins Cheddar News to discuss how to celebrate safely.
