CNN —A reality show contestant who killed and ate a protected bird has been let off with a warning after New Zealand wildlife officials said cast members were tired, hungry and placed in a “unique” situation. Spencer “Corry” Jones, an American white water river guide, killed and ate the large, flightless weka during filming of “Race to Survive: New Zealand” last fall, CNN affiliate RNZ reported Tuesday. Swain said the producers of “Race to Survive” had a permit to film on public conservation land and were aware that protected species and plants could not be harvested or eaten. In a statement, “Race to Survive” production said it alerted authorities as soon as they became aware of the weka incident. New Zealand has a plethora of unique flora and fauna due to its long geological isolation from the supercontinent Gondwana, according to independent conservation organization Forest and Bird.

Creatures living in the far south have been harder to pin down, and less is known about the animals that lived closer to the poles. It thrived as a top predator 40 million years before dinosaurs evolved to roam the Earth, according to the study. “It’s really, really surprising that Gaiasia is so archaic. In addition to seeking more fossil examples of the species, the researchers are also curious to find other animals that lived in this far south ecosystem. “It tells us that what was happening in the far south was very different from what was happening at the equator.

A team of international academics successfully sequenced the genomes of each of the eight baobab species, examining their relationship with one another and concluded that they originated in Madagascar. "Avenue of the Baobabs" in Western Madagascar is one of the most spectacular collections of the unusual trees. Gavinevans/Creative CommonsOnly one baobab species is not included in the IUCN’s Red List of Threatened Species: A. digitata, which populates mainland Africa. The likelihood of finding fossil evidence to rubberstamp the conclusions of the genetic data is slim, Dr. Wan conceded. So perhaps these majestic trees may retain some of their mystery after all.

☆ An ancient missing continent was finally rediscovered 155 million years after it vanished

A chunk of land that broke off from Australia 155 million years ago seemed to have vanished. AdvertisementAdvertisementThe continent of Argoland, which seemingly vanished after splitting from Australia 155 million years ago, has finally been discovered, according to a new study. The discovery could help explain something known as the Wallace line, which is an imaginary boundary that separates Southeast Asian and Australian fauna. With this work, they were finally able to bring Argoland's journey over the past 155 million years back to life. A map shows an approximate location of the Wallace line.

☆ Ancient landscape formed by rivers revealed deep under Antarctic ice

Researchers said on Tuesday they have detected buried under the continent's ice sheet a vast ancient landscape, replete with valleys and ridges, apparently shaped by rivers before being engulfed by glaciation long ago. Ancient palm tree pollen has been discovered from Antarctica, not far around the coast from our study site," Jamieson added. Some previous studies similarly have revealed ancient landscapes beneath Antarctica's ice including mountains and highlands, though the landscape discovered in the new study was the first of its type. Right before 34 million years ago, Antarctica's landscape and flora likely resembled today's cold temperate rainforests of Tasmania, New Zealand and South America's Patagonia region, Ross added. When that ice growth occurred, the conditions between the base of the ice and the landscape changed to become very cold - and in this way it was no longer able to erode our landscape.

☆ Scientists finally finished mapping Earth's 8th continent Zealandia, helping them solve the lost continent's mysterious history

But that didn't deter scientist Nick Mortimer, who led the team that's been studying Zealandia for over 20 years. AdvertisementAdvertisementIn a new study, the team finished mapping the final piece of the continent, the northeast corner. As a result, the scientists believe they've mapped Zealandia more thoroughly than any other continent on Earth.

☆ A mystery 300-mile wide formation lurking beneath Australia may be the largest asteroid impact crater on Earth
▼ + stars: | 2023-08-15 | by ( Marianne Guenot | ) www.businessinsider.com time to read: +4 min

Scientists have uncovered traces of what they think could be the world's largest asteroid impact. The impact might have occurred 450 million years ago, wiping out 85 percent of Earth's species, one said. The structure, the scientists say, could be the remnants of an enormous asteroid impact that hit the Earth hundreds of millions of years ago. If confirmed, it would be the largest asteroid impact on record. The memory of the impact is hidden in the groundOne would think finding the world's largest asteroid impact should be fairly easy.

☆ There's an enormous gravity hole in the middle of the Indian Ocean. Scientists say they've finally worked out what's causing it.

There's a gravity hole in the Indian Ocean, where ocean levels are about 300 feet lower than surrounding areas. The gravity hole may have been caused by an ancient ocean bed that sank millions of years ago. But a new study suggests researchers should have been looking around, not under, the gravity hole to solve the mystery of how it formed. The blue dot over the Indian Ocean is a gravity 'hole' that has scientists baffled. But scientists have struggled to explain the gravity hole in the Indian Ocean, known as the Indian Ocean geoid low.

Oamenii de știință au găsit în Chile fosile ale unei noi specii de mamifer care a trăit în urmă cu 72 de milioane de aniFosile ale unei noi specii de mamifer din Cretacicul Superior, cu o vârstă cuprinsă între 72 de milioane şi 74 de milioane de ani, au fost descoperite în Patagonia de pe teritoriul statului Chile, a anunţat miercuri Institutul Chilian Antarctic (INACH). Descoperirea a fost realizată pe teritoriul unui sit considerat unul dintre cele mai mari rezervoare de fosile de dinozaur din regiune. Noua specie, denumită Orretherium tzen, a fost descoperită în Cerro Guido, din regiunea Magallanes, situată la circa 2.700 de kilometri sud de Santiago de Chile, unde cercetătorii au găsit resturi dintr-o mandibulă cu cinci dinţi consecutivi, notează AFP, citată de digi24.ro. Potrivit cercetătorilor, zona a fost locuită de specii preistorice din America şi Antarctica, care au migrat în urmă cu milioane de ani traversând fâşii de pământ aflate sub ape şi care au ieşit la suprafaţă după scăderea temperaturilor. Specimenul era înrudit cu alte mamifere descoperite în Patagonia de pe teritoriul Argentinei.
