The fossil leg bone of an extinct terror bird that was found in Colombia's Tatacoa Desert is shown. While some terror bird fossils have been found in Florida and Texas, the specimen from La Venta is believed to be the northernmost terror bird from South America documented by scientists. Placing terror birds in La Venta “is one step closer to understanding how terror birds finally got to North America,” Degrange said. A map shows the countries in North America and South America (in gray) where terror bird fossils have been found. “We know that probably one of the drivers that led terror birds to get larger and larger was the competition between species of terror birds — but why that big?” he said.

Tiger populations in Thailand are bouncing back

CNN —As Global Tiger Day rolls around, there’s good news for the big cats in Thailand. Thailand Department of National Parks, Wildlife and Plant Conservation/WCS ThailandThe DNP began working with WCS to “build and strengthen site-based protection,” says Jornburom. Thailand Department of National Parks, Wildlife and Plant Conservation/WCS ThailandA ‘conservation-dependent species’While Thailand’s success story offers hope, the outlook across the region is not so optimistic. This has left small, isolated tiger populations in Myanmar, Indonesian Sumatra, and peninsular Malaysia — the latter of which is worrying conservationists after a recent spate of tiger deaths. WEFCOM currently boasts most of the country’s tiger population, and has the potential to support up to 2,000 tigers, according to WCS.

They’re also plumbed by blood vessels, which lead all the way from the heart. By the time blood vessels reach these extremities, like twigs from a tree, they have branched and got much smaller in size. This rare condition is sometimes called “trash foot,” because of the way in which the feet become so discolored. In adults, however, finding the Babinski sign is an altogether different story. In some otherwise healthy people though, the Babinski sign can be observed during deep sleep.

Zelensky and Trump loom over DavosTwo people are having an outsize impact at the World Economic Forum, and one of them isn’t even there. One is Volodymyr Zelensky, Ukraine’s president, who put on a full-court press of business and global leaders at the forum in Davos, Switzerland. Zelensky isn’t the only leader at Davos worried about Trump. The Ukrainian leader has sought to shore up global business support. And the annual wine tasting hosted by Anthony Scaramucci, the financier and former Trump official, well, ran out of wine.

North America used to be crawling with giant mammals, from dire wolves to big cats. In North America, "you only get the woolly mammoths up in the north, starting around the Great Lakes," Lindsey said. AdvertisementOnce thought to be the cousins of gray wolves, dire wolves evolved separately over 5 million years ago in North America. AdvertisementThe ancient bison, Bison antiquus, was 25% larger than those living today. A recent study suggested modern bison — Bison biso — evolved from this species.

Deer Are Everywhere, but We Barely Know Them

On June 4, 2013, Buck 8917 did something weird, for a deer: He took a long, purposeful walk. Researchers from Penn State had captured and put a GPS collar on the adult male that spring in Bald Eagle State Forest, about 15 miles northeast of State College, Pa. Put a tracker on most deer and you’ll find they stick pretty close to their home range, which was true for 8917. Then, in 2015, after two mating seasons, two hunting seasons and thousands of laps around his home range, Buck 8917 died — unsurprising given he was about 4 years old. Now in its 10th year, the study has tracked more than 1,200 white-tailed deer around 100 square miles of Pennsylvania forest.

Giovanni Bianucci/Handout via REUTERSAug 2 (Reuters) - Move over, blue whale. The biggest-known blue whale weighed around 190 tons, though it was longer than Perucetus at 110 feet (33.5 meters). Its skeletal mass alone was estimated at between 5 and 8 tons, at least twice that of the blue whale. The researchers suspect Perucetus lived like sirenians - not an active predator but an animal that fed near the bottom of shallow coastal waters. The researchers said it was unlikely Perucetus was a filter-feeder like today's baleen whales including the blue whale.

It may have weighed twice as much as a blue whale because of its dense bones. That's nearly as heavy as a Boeing 747 or twice as much as a blue whale, which typically weighs between 72 and 180 tons. That means the other fossils retrieved from the area may not offer clues to how P. colossus lived. A 3D model shows what a complete skeleton of Perucetus colossus would look like, above a blue whale and smaller Cynthiacetus peruvianus skeletons. No limbs were found near the P. colossus skeleton, but fossilized evidence suggests it likely had both front and back legs.

Joelinton scored Newcastle's second goal. Alex Dodd/CameraSport/Getty ImagesEvery attack seemed to yield a corner, an opportunity, a shot on goal and Newcastle continued to press while Tottenham’s defense continued to buckle. And then, barely two minutes after kickoff, there was another for Isak who made it five goals for the Tyneside club in 21 minutes. “It’s very embarrassing,” Lloris told Sky Sports afterwards. We didn’t show a good face and we could not match the performance of the Newcastle players.”
SYDNEY, Oct 30 (Reuters) - An international traveller has been fined and refused entry to Australia after trying to bring meat into the country in what the government said on Sunday was a "significant breach" of biosecurity laws to protect Australia from foot and mouth disease. Australia earlier this year stepped up protection against foot and mouth disease at its international airports following an outbreak in Indonesia. "Australian biosecurity officers uncovered the undeclared meat during a baggage inspection at Perth Airport (on) October 18," the ministers said. “This is why legislation is in place to cancel the visa of any traveller who commits a significant biosecurity breach or repeatedly contravenes biosecurity laws,” she said. The government has estimated a large outbreak in Australia could see revenue losses of up to $A51.8 billion ($33.2 billion) over ten years.
