Dinosaurs would have kept right on living, had an asteroid not wiped them out. That’s according to new research from the University of Bath and London’s Natural History Museum.
While it’s recently been en vogue to claim that dinosaurs were seeing their time of planet-wide domination come to an end even before a massive impact hurried them off the Earth, this new study claims that dinosaurs would have lived on.
The theory this study refutes claims that dinosaur species diversity was dwindling, a sign that the entire branch of the animal kingdom was winding down while avians and mammals were on the rise.
“What we found is that the dinosaurs were still dominant, they were still widespread and still doing really well,” explained lead author Joe Bonsor. “If the asteroid impact had never happened then they might not have died out and they would have continued after the Cretaceous.’
Bonsor and his fellow researchers believe that the prior theory is based on gaps in the fossil record and not hard evidence. Dinosaurs were an incredibly diverse group of animals that lived for hundreds of millions of years. While many of them died in that time, most of their remains were not fossilized. Bonsor thinks that the theory of diversity decline is based on lack of fossils and not proof.
He said: “Previous studies done by others have used various methods to draw the conclusion that dinosaurs would have died out anyway, as they were in decline towards the end of the Cretaceous period.
“However, we show that if you expand the dataset to include more recent dinosaur family trees and a broader set of dinosaur types, the results don’t actually all point to this conclusion – in fact only about half of them do.”
Scientists at North-Eastern Federal University (NEFU) in Yakutsk, Russia, on Monday announced a finding of “great importance” — a preserved Ice Age cave bear carcass, estimated to be to be between 22,000 and 39,500 years old.
Even the bear’s nose is still intact, the university said in a statement.
The preserved bear was found by reindeer herders on Bolshoy Lyakhovsky Island, part of the Lyakhovsky Islands archipelago in northern Russia, according to a statement from NEFU.
“Today this is the first and only find of its kind — a whole bear carcass with soft tissues,” scientist Lena Grigorieva said in a statement. “It is completely preserved, with all internal organs in place.
- “Negative interest rates are inevitable in the U.S.,” said Bankrate’s Greg McBride. “It’s just a matter of when.”
- For everyday Americans, that would likely mean lower mortgage and credit card rates and even lower returns on savings, if any at all.
The South Korean military responded by broadcasting a verbal warning and returning fire twice, according to protocol outlined in the response manual and on the judgment of the field commander, according to the JCS statement.The South Korean military said that “the military is in the process of identifying situations over the military communication line with the North and preventing any additional situations from occurring.”Under the military accord signed between the two Koreas on September 29, 2018, the South and North each demolished 11 guard posts along the DMZ, but dozens of guard posts remain.There have been exchanges of fire between the Koreas in the past, including in 2017, when a North Korean solider defected at the JSA (Joint Security Area) and, in 2014, when a North Korean defector organization launched balloons of leaflets criticizing the country’s reclusive regime.It is not known what caused this exchange of fire.
The tiny fossil is unassuming, as dinosaur remains go. It is not as big as an Apatosaurus femur or as impressive as a Tyrannosaurus jaw. The object is a just a scant shard of cartilage from the skull of a baby hadrosaur called Hypacrosaurus that perished more than 70 million years ago. But it may contain something never before seen from the depths of the Mesozoic era: degraded remnants of dinosaur DNA.
Genetic material is not supposed to last over such time periods—not by a long shot. DNA begins to decay at death. Findings from a 2012 study on moa bones show an organism’s genetic material deteriorates at such a rate that it halves itself every 521 years. This speed would mean paleontologists can only hope to recover recognizable DNA sequences from creatures that lived and died within the past 6.8 million years—far short of even the last nonavian dinosaurs.
But then there is the Hypacrosaurus cartilage. In a study published earlier this year, Chinese Academy of Sciences paleontologist Alida Bailleul and her colleagues proposed that in that fossil, they had found not only evidence of original proteins and cartilage-creating cells but a chemical signature consistent with DNA.
The Bible, which has survived more than four centuries, was one of more than 300 items allegedly stolen from the Carnegie Library of Pittsburgh as part of a 20-year scheme by a former archivist Gregory Priore, 62, and rare books dealer John Schulman, 54, local outlet KDKA reports, both of whom had long worked closely with the library. They have been charged with theft, conspiracy and forgery, among other counts.
Investigators traced the tome to the American Pilgrim Museum in Leiden, which had paid about $1,200 for it. Allegheny County District Attorney Stephen Zappala explained that the director of the Leiden museum realized the Bible it had purchased belonged to the Carnegie Library and reached out to the institution. He’s “an honest man,” Zappala said, according to KDKA.
The agency attributed the high number of cases primarily to a few large outbreaks — one in the state of Washington and two others in New York City and New York state. The New York outbreaks are among the largest and longest lasting since 2000.
“The longer these outbreaks continue, the greater the chance measles will again get a sustained foothold in the United States,” the CDC said.
Health and Human Services Secretary Alex Azar said, in a statement, said the rise in measles cases is “avoidable.”
“Measles is not a harmless childhood illness, but a highly contagious, potentially life-threatening disease,” he said. “We have the ability to safely protect our children and our communities. Vaccines are a safe, highly effective public health solution that can prevent this disease. The measles vaccines are among the most extensively studied medical products we have, and their safety has been firmly established over many years in some of the largest vaccine studies ever undertaken.”
