Ancient Fossils of Land-Dwelling Animals Found in Australia Dating Back 380 Million Years

Paleontologist at Flinders University brian chu and his colleagues described a new genus and species of Devonian tetrapod fish based on several nearly complete skulls and postcranial skeletons.

Tetrapodomorpha “It consists of tetrapods and their closest fish relatives, the oldest records of which are from the Pragians of China,” said Dr Chu and co-authors.

“This group diversified greatly in both marine and freshwater habitats during the Middle to Late Devonian, giving rise to several distinct lineages, including the earliest quadrupeds.”

“Tetrapods flourished after the Devonian limbless fish tetrapods experienced a marked decline in diversity during the Carboniferous, but only survived into the early Permian before disappearing from the fossil record. There were only a handful of representative animals.”

This new species of tetrapod lived about 380 million years ago and was up to 45 to 50 centimeters long.

with scientific name Harajikadectes zuminithis fish is particularly distinctive for its large opening at the top of its skull.

“These spire-like structures are thought to facilitate air breathing at the surface, and modern African bichir fish have similar structures for taking in air at the surface,” said Dr Chew. Ta.

“This feature appears in multiple tetrapomodorf lineages at about the same time during the middle to late Devonian period.”

“In addition to Harajikadectes zumini Large spiracles also appeared from central Australia. gogonathus El Pisto Stegarian from Western Australia Tiktaalik — are the closest relatives of four-limbed quadrupeds. ”

“And it shows up in unrelated places.” Pickeringius Western Australian stingray fin fish first described in 2018. ”

Professor John Long from Flinders University said: “This synchronous emergence of air-breathing adaptations may have coincided with a period of reduced atmospheric oxygen during the mid-Devonian.”

“The ability to supplement gill breathing with oxygen from the air may have provided an adaptive advantage.”

“We discovered this new form of lobe-finned fish in one of the most remote fossil sites in all of Australia, the Harajika Sandstone Formation in the Northern Territory, about 200km west of Alice Springs. It dates from the mid-Devonian period. Late period, approximately 380 years ago.'' 1 million years old. ”

“It's difficult to pinpoint the location. Harajikadectes zumini sit in this group of fishes because they appear to have convergently acquired a mosaic of specialized features characteristic of widely separate branches of the tetrapod radiation. ”

of findings will appear in Journal of Vertebrate Paleontology.

Spotify reportedly seals new deal with Joe Rogan potentially worth $250 million

Spotify Technology announced a new multi-year deal with comedian and podcaster Joe Rogan on Friday, with the goal of leveraging the show’s popularity to increase advertising revenue.

The estimated $250 million multi-year deal with Rogan includes a guaranteed minimum upfront payment and a revenue-sharing agreement based on ad sales. According to a report from the Wall Street Journal, the company declined to confirm the terms of the deal, but stated that the reported value was incorrect.

The Joe Rogan Experience Podcast, which premiered in 2009, has been exclusively available on Spotify since 2020 and is promoted as the most listened to podcast globally.

Spotify also announced plans to make Joe Rogan’s show available on other platforms, including Apple, Amazon, and YouTube.

Joe Rogan interviews prominent politicians, businessmen, and celebrities on his podcast, such as director Quentin Tarantino, singer Miley Cyrus, and Tesla CEO Elon Musk.

The Sweden-based company is focused on increasing advertising revenue on its platform through the Spotify Audience Network, an advertising marketplace for podcast publishers and creators.

“Since podcasts became exclusive to Spotify, overall podcast consumption on the platform has increased by 232%,” the company stated, noting that revenue from the previous year had risen by 80% compared to 2021.

Spotify first introduced podcasts in 2015 and has since made significant investments in the medium. It acquired podcast networks Gimlet Media and Anchor FM in 2019 and secured exclusive contracts with reality TV star Kim Kardashian and former US President Barack Obama. However, the company has since scaled back its ambitions and laid off 200 Gimlet Media employees.

James Dyson’s donation of £6 million to primary schools given the go-ahead despite reservations

The Government has approved a donation of £6 million from Sir James Dyson to fund the expansion of a local state primary school, Malmesbury Anglican Primary School in Wiltshire, near Dyson’s research and development campus, despite concerns about the potential impact on nearby schools.

Education Secretary Gillian Keegan announced the approval on Monday, revealing that the donation will fund a ‘first class’ Science, Technology, Engineering, Arts and Mathematics (STEM) center, additional classrooms, and space for 210 more pupils, with an opening date in September 2027, subject to planning permission by Wiltshire Council, bringing the total capacity to 630 students.

The James Dyson Foundation, which is responsible for the donation, has not officially welcomed the approval and is considering the details of the decision carefully.

In a letter to the Times last year, Mr Dyson expressed his disappointment with his charity’s donations being blocked and described the difficulty of getting things done in the UK.

This claim was denied by Downing Street, but local opposition from Laura Mays, Wiltshire Council’s cabinet member for children’s services, suggested that there is already enough space in three local schools to meet demand.

Reports indicate that many employees at Dyson’s UK headquarters in Malmesbury would like to send their children to the school, but the current size does not accommodate this.

Education Secretary Gillian Keegan expressed her appreciation for the generous donation from the Dyson Foundation, emphasizing the support it will provide for local students and the development of future scientists and engineers.

Malmesbury Primary School’s headteacher, Steve Heal, expressed gratitude for the foundation’s support, highlighting the long journey to reach this point and the innovative curriculum created in collaboration with Dyson.

Laura Mays, following the government’s announcement, emphasized the importance of providing opportunities for all students and assured that the council will work with all parties involved to ensure the best outcome for all students.

Former education secretary Kenneth Baker supported Dyson’s efforts and questioned the government’s decision to reject the proposal, suggesting that it could discourage other industries and entrepreneurs from investing in technical education in schools.

Biden administration allocates $623 million to enhance electric vehicle charging infrastructure, White House reports

President Joe Biden’s administration has announced $623 million in funding to increase electric vehicle charging points in the U.S. amid concerns that the transition to zero-carbon transportation is not keeping pace with goals to tackle the climate crisis.


The money will be distributed as grants to dozens of programs across 22 states, including EV chargers for multifamily housing in New Jersey, fast chargers in Oregon, and hydrogen fuel chargers for cargo trucks in Texas. In total, funds pulled from the bipartisan infrastructure law are expected to add his 7,500 chargers across the United States.

“We’re building the charging network to win the EV race,” said U.S. Secretary of Transportation Pete Buttigieg.

“The electric vehicle revolution is not coming, it is here. I very personally recognize the importance of the fact that America led the world in the automobile revolution. We’re in the middle of a second automotive revolution, and it’s important that America has one again.”

There are about 170,000 electric vehicle chargers in the U.S., a significant increase from a network that was nearly invisible before Biden took office, and the White House is helping the transition away from gasoline and diesel vehicles. The company has set a goal of selling 500,000 chargers.

Biden’s climate change adviser, Ali Zaidi, said that “America is leading the way globally on electric vehicles” and that the U.S. is on track to “meet and exceed” the administration’s charger goals. He said there was. He added: “This expansion will continue over the coming years and decades until we reach net zero in the transport sector.”

Sales of electric vehicles are growing in the United States, with more than 1 million EVs sold for the first time last year, accounting for 9% of all car sales. But that rate of growth has slowed somewhat, with companies like Ford, General Motors and even Tesla scaling back their EV ambitions in recent months.

U.S. motorists are faced with an ever-expanding selection of EVs, but most are still more expensive than their gasoline equivalents, meaning they are out of reach for many buyers. research has discovered The median household income for EV buyers is $186,000.

Research shows that nearly one-third of potential EV buyers discount their purchase due to lack of charging infrastructure, despite accounting for most of the total vehicle trips in the United States. Masu. 3 miles or less. Even if Biden’s goal of 500,000 chargers is met, this is far fewer than is needed to support a gradual transition away from polluting cars. Estimate It is predicted that more than 28 million chargers will be needed by 2030.

Skip past newsletter promotions

“In the U.S., EV penetration is growing at almost twice the rate of charger installations,” said Brent Gruber, executive director of J.D. Power’s electric vehicle business. said last year. “Construction of new charging stations is not keeping up with demand.”

Earlier this week, the Environmental Protection Agency announced nearly $1 billion in grants to replace diesel-powered school buses with electric and low-emission vehicles. EPA will disburse the funds to 280 school districts serving 7 million children nationwide. Charging infrastructure is also an issue in efforts to phase out diesel buses.

Ancient sponge fossil unearthed in Ireland by paleontologists dating back 315 million years

Remarkable new species over 50 cm (20 inches) tall Chiatophicus varori is the largest known member of its genus theatophicus and one of the largest sponges in the order mesh.

theatophicus “This is one of the most widely distributed Ordovician and Silurian sponge genera, recorded throughout the Iapetus region and tentatively in Bohemia,” said lead authors Ballen and Moher. said Dr Eamon Doyle, geologist at the Cliffs UNESCO Global Geopark, and colleagues. .

“This genus was widely distributed in offshore marine environments from the Middle Ordovician to the Middle Devonian, but has not previously been recorded in rocks from that period.”

named Chiatophicus varorithe newly identified species lived during the Carboniferous period, about 315 million years ago.

When alive, the vase-shaped sponge had a circular opening at the top surrounded by a ring of eyelash-like structures.

Probably similar to modern times Venus flower basket spongefound in the Pacific Ocean and often featured in deep-sea wildlife documentaries.

“This is a very large example of a type of fossil sponge that was previously only known from much older rocks elsewhere in the world,” Dr Doyle said.

“This is the first record of a sponge fossil of this type found in Ireland and its excellent state of preservation is extremely rare.”

specimen of Chiatophicus varori collected from Kilkee Cyclosem, Central Clare Group, Namuria, County Clare,Ireland.

“Sponges originally consisted of a rectangular network of tiny needles made of silica, held together by a thin organic membrane,” Dr Doyle said.

“Normally they fall apart quickly after death, and often only scattered remains of the needles are preserved as fossils, so we were delighted to find these nearly intact specimens. .”

“This wonderfully preserved fossil dates back to a time when the Atlantic Ocean had not yet begun to form, and the area now known as County Clare was part of an early ocean located near the equator.”

“Discoveries like this help raise awareness of the amazing geological heritage we have here on our doorstep in County Clare, and inspire a new generation of palaeontologists – geologists who specialize in the study of fossils. will help encourage people to visit and learn more about the unique geology of Ireland's west coast. ”

“We were surprised by the size and well-preserved condition of this fossil. This was completely unexpected,” said lead author Dr. Joseph Botting, a researcher at Amgefa Shimul Museum in Wales and the Nanjing Institute of Geology and Paleontology. said.

“This discovery provides important insight into the evolution of sponges and how some species are able to survive in niche environments where most other species cannot live. It is unusual for a specimen to be found.”

“This is a fantastic discovery and a reminder that new and interesting fossils are still being discovered that help us understand the story of life on Earth,” said the co-authors, from the Amgefa Cymru Museum in Wales. said Dr. Lucy Muir, a researcher at . .

A ‘Giant’ Predator Roamed the Waters of Greenland 518 Million Years Ago

It has fins on the sides of its body, a unique head with long antennae, a huge jaw structure in its mouth, and can grow to over 30 cm (11.8 inches) in length. Timole Bestia Copley It was one of the largest animals in the ocean during the early Cambrian period.

Timole Bestia Copley They lived in the early Cambrian oceans over 518 million years ago.

The fossilized remains of this animal were discovered in Fossil locality of Sirius Passet in northern Greenland.

“We previously knew that the main predators of the Cambrian were primitive arthropods, including the bizarre-looking anomalocariids,” said Dr Jacob Binther, a palaeontologist at the University of Bristol.

“but, Timole Bestia Copley is a distant but close relative of a living caterpillar; or Chetognath. These are much smaller marine predators today, feeding on small zooplankton. ”

“Our study shows that these ancient marine ecosystems were fairly complex and had food chains that tolerated multiple layers of predators.”

Timole Bestia They were the giants of their time and would have been near the top of the food chain. As such, they are as important as major carnivores in the modern ocean, such as Cambrian sharks and seals. ”

Inside a fossilized digestive system Timole Bestia CopleyDr. Vinther et al. Isoxis.

“We can see that these arthropods were a food source for many other animals,” says palaeontologist Dr Morten Lunde Nielsen of the Korean Polar Research Institute, the University of Bristol and the British Geological Survey.

“They were very common in Sirius Passet and had long protective spines pointing both forward and backward.”

“But it is clear that they could not completely avoid that fate. Timole Bestia I munched on them in large quantities. ”

“Arrowworms are one of the oldest animal fossils from the Cambrian period. Arthropods appear in the fossil record about 521 to 529 million years ago, but arrowworms appear in the fossil record at least 500 million years ago. It can be traced back to 38 million years ago,” Dr. Vinter said.

“Both arrowworms and more primitive arrowworms, Timole Bestia, was a swimming predator. Therefore, we can infer that they were likely predators that dominated the oceans before arthropods took off. ”

“They probably had a dynasty for about 10 to 15 million years before being replaced by other more successful groups.”

Timole Bestia “This is a hugely important discovery for understanding where these jawed predators came from,” said Dr Luke Parry from the University of Oxford.

“Today, the caterpillar has formidable setae on the outside of its head to catch prey, but Timole Bestia There is a jaw in the head. ”

“This is the bearded bug that we can see under a microscope today, and it is an organism that shared an ancestor with the bearded bug more than 500 million years ago.”

Timole Bestia And other fossils like it provide a link between closely related organisms that look very different today. ”

“Our discovery confirms how the beetles evolved,” said Dr. Taeyoon Park, a paleontologist at the Korea Polar Research Institute.

“The abdomen of living arrowworms has a unique nerve center called the ventral ganglion. It is completely unique to these animals.”

“I found this saved. Timole Bestia and another fossil called Amiskwia

“People are, Amiskwia As part of the evolutionary stem lineage, it was closely related to the caterpillar. ”

“The preservation of these unique ventral ganglia gives us even more confidence in this hypothesis.”

Epic Games CEO Criticizes Google’s $700 Million Settlement with US States as Unjust to Android Users

Google agreed to pay $700 million and allow more competition within the Android app store as part of a settlement with all 50 states and millions of U.S. consumers, but Epic Games CEO Tim Sweeney denounced the deal as “unfair to all Android users and developers.” ”

The exact terms of the settlement, first reached in September, were announced just days after Google was handed a major legal defeat in a related lawsuit with Epic Games, best known as the maker of Fortnite.

As part of the lawsuit, U.S. District Judge James Donato is expected to order sweeping changes that could upend Google’s lucrative app store.

In its settlement with states, Google targeted consumers who may have overpaid for apps as a result of Google’s practices, according to terms detailed in documents filed Monday in San Francisco federal court. It plans to contribute $630 million to the settlement fund.

This equates to just $6 per person when divided evenly among 102 eligible U.S. consumers.

All eligible consumers will receive a minimum of $2. The state said at least 70% of consumers should automatically receive their share of the settlement.

The remaining $70 million will be earmarked for the state to use to cover various fines and legal costs.

Google also agreed to a series of time-bound changes to its app store practices.

This includes allowing developers to use other in-app purchase systems for the next five years, dialing back the use of so-called “horror screens” when Android users try to use competing app stores (but This includes making it easier for users to use it. Download apps directly from developers.

A coalition of state attorneys general says Google’s dominance in the Android software market – taking up to 30% fees from big developers in the Play Store – has resulted in higher prices and fewer choices for consumers. He claimed to be inviting.

Epic used the same argument in its successful battle with the company.

In a series of scathing tweets, Sweeney criticized the states that accepted the deal.

“The settlement with the state attorney general is unfair to all Android users and developers,” he wrote, adding that the settlement was “intentionally designed by Google to disadvantage competing stores and direct downloads.” It supports a misleading, anti-competitive and scary screen.”

“Previous U.S. lawsuits have made a strong case for $10.5 billion in damages, as well as a 30% fee that Google wrongly collected,” Sweeney added. “I think they would have been satisfied if they had continued to fight for a few more weeks until they won a resounding victory in court. It was a disappointing outcome.”

The terms of the settlement could not be disclosed until the end of the separate Google v. Epic case. Epic was particularly opposed to the settlement when it was first announced in September.

The settlement still needs formal approval from Donato, who presided over each state’s case, before it becomes effective.

During the trial, Donato accused Google of “disturbing” efforts to delete employee chat logs it was ordered to keep.

Luther Rowe, an antitrust watchdog and longtime Google adversary, said: described the settlement as a “scandal” That could derail another major antitrust battle, the Justice Department’s landmark case targeting Google’s online search business.

“Not only was the fine an order of magnitude larger than it should have been, but[RI AG]won a $250 million settlement in 2012 with Company G, which didn’t even split with anyone for not blinking. (remember), the fine was lowered in mid-2012. The US v. G case was designed to make it seem as though it was unreasonable for the Department of Justice and the state in the case to bring it to the finish line. It seems as if the

Elsewhere, Wilson White, Google’s vice president of government affairs and public policy, said he was “pleased” to resolve the dispute with the state and that efforts to challenge the Epic lawsuit verdict were still “not over.” ‘ he claimed.

Google suffered a huge loss in its recent battle with Epic Games. AP

“We are pleased to be able to reach an agreement on that basis and to advance Android and Google Play for the benefit of millions of developers and billions of people around the world. We look forward to making these improvements that will help.” White said in a blog post..

Washington, D.C. Attorney General Brian Schwalb was among those touting the settlement as a victory for consumers.

“For too long, Google’s anticompetitive practices in app distribution have deprived Android users of choice and forced them to pay artificially high prices,” Schwalb said in a statement.
