A fossilized mandible unearthed in the Pyrénées-Atlantiques in France belongs to a species of amphicyonid unknown to date, say paleontologists associated with the Museum of Natural History in Basel, Switzerland.
Better known as bear dogs, Amphicyonidae are an extinct family of large carnivorous mammals. These animals, closely related to canids, inhabited much of the Northern Hemisphere.
Appeared in the Eocene (36 million years ago) and disappeared in the middle Miocene (7.5 million years ago), they represent one of the most characteristic groups of predators of the ancient fauna. European.
Their body mass ranged from 9 to 320 kg and their diet was typically mesocarnivorous, omnivorous, bone-crushing and hypercarnivorous,” notes paleontologist Bastien Mennecart in a statement released by the museum. The mandible was unearthed in the small town of Sallespisse, in the Pyrénées-Atlantiques department in southwestern France. It was extricated from a marine deposit 12 to 12.8 million years old.
Scientists were struck by the dentition of the lower jaw.
The team named the beast Tartarocyon cazanavei, a name inspired by the character of Tartaro, a one-eyed giant from Basque mythology.
The body mass of a Tartarocyon is estimated at 200 kg, making it one of the largest predators that lived in European territory during the Miocene.
Fossil discoveries of terrestrial vertebrates that lived 13 to 11 million years ago in the northern Pyrenees are very rare, the statement noted. This discovery and the description of the lower jaw are all the more important. They offer the opportunity to better understand the evolution of European bear dogs in the environmental context of the time.
The details of this work are published in the journal PeerJ (in English).

Each two weeks,I will choice a great retro classic movie for you and will explain why I made this choice!
This week,my eyes turn on a great science fiction movie of the drive-in era: Voyage to the prehistoric planet,a 1965 movie!
In 2020, after the colonization of the moon, the spaceships Vega, Sirius and Capella are launched from Lunar Station 7. They are to explore Venus under the command of Professor Hartman, but an asteroid collides and explodes Capella. The leader ship Vega stays orbiting and sends the astronauts Kern and Sherman with the robot John to the surface of Venus, but they have problems with communication with Dr. Marsha Evans in Vega. The Sirius lands in Venus and Commander Brendan Lockhart, Andre Ferneau and Hans Walter explore the planet and are attacked by prehistoric animals. They use a vehicle to seek Kern and Sherman while collecting samples from the planet. Meanwhile John helps the two cosmonauts to survive in the hostile land.
Cast: Basil Rathbone, Faith Domergue, John Bix
Why I take this movie?Because the action is preview for…2020!
In the next 30 years, five billion people, particularly in Africa and South Asia, may be facing a shortage of drinking water and food. Hundreds of millions more living in coastal areas could be hit by catastrophic floods. This is revealed by a modeling of services that nature will still be able to offer to human populations around the world in 2050 given the rapid decline in biodiversity, the results of which are published in the journal Science.
The most recent report of the Intergovernmental Platform on Biodiversity and Ecosystem Services (IPBES) informed us that one million species are threatened with extinction and that the benefits that humans gain from nature would decrease accordingly. Nature contributes to the well-being of human populations in a variety of ways. It can be in the form of food resources through fishing and agriculture, or more indirectly by contributing to water purification, crop pollination and coastal protection against the devastating effects of storms, for example.
An international team led by Becky Chaplin-Kramer of Stanford University wanted to know where, in the world, the contributions of nature are most needed to ensure the well-being of the people and which populations in particular will scoop the most. nature degradation, in order to plan more targeted actions that would prevent damage.
To do this, researchers have mapped the needs, or even the dependence, of the different populations of the world on three particular services that nature provides them. The service provided by wetland plants and algae that filters pollutants, such as excess nitrates from fertilizers used to increase crop yields, and thereby provide access to drinking water. The service provided by coral reefs, mangroves, seagrasses and salt marshes that mitigate coastal erosion and thereby reduce the impact of flood, wind and water level flooding. from the sea. And the service provided by natural pollinators, such as bees, which ensure fertile crops.
They also mapped nature’s current contributions to nitrate retention, coastal protection and crop pollination around the world. And they have pinpointed, with a precision of 300 meters by 300 meters, the places where these contributions are not enough to meet the needs of the populations, probably because of the degradation of nature, which results notably the presence of pollutants in the increased risk of flooding in coastal areas and crop losses as a result of insufficient pollination.
Using a modeling platform, researchers were then able to predict the impacts of various future scenarios on nature’s ability to meet the needs of human populations. They calculated that, regardless of the scenario, nearly five billion humans may no longer have secure access to safe drinking water and food for their survival in 2050. And hundreds of millions of people living in coastal areas will no longer be protected from the weather.
The researchers also noted that people in Africa and South Asia are facing the greatest threats of famine, lack of drinking water and floods as a result of the degradation of nature. especially those in the Ganges Basin, East China and sub-Saharan Africa, populations that, in addition, rely heavily on nature for their survival.
This study helps to guide the actions that must be taken to mitigate the damage, argue the researchers. According to Elena Bennett of the Department of Natural Resource Sciences at McGill University, « to solve the problems facing the people of South Asia, you can not just tell them to do better management [of their resources] » .
« We must also consider the role that we, the inhabitants of North America, play in their problems by buying various products from South Asia, whether food, holidays in their tourist resorts or even exploitation. of Canadian industries. We are generating pollution there rather than here, « says Bennett, who is one of the authors of the study.

An hour after the House of Representatives, the US Senate also adjourned Friday night without being able to reach an agreement to avoid the partial paralysis of the federal government at midnight.
Senators gave themselves rendezvous at noon on Saturday to resume negotiations.
The main representatives of Mr. Trump tried to negotiate a last-minute compromise with Democrats and some Republican lawmakers. However, despite the presence of the vice president Mike Pence, the Acting Chief of Staff of the White House Mick Mulvaney and close adviser to President Jared Kushner, no agreement has been concluded.
President Donald Trump insists on a budget of five billion dollars for the construction of a wall on the US-Mexico border. A request that the Democratic Party strongly rejects.
Without an agreement on the budget, financing about 25 percent of the US federal government activities end at midnight.
Nine departments and dozens of agencies are affected including homeland security, transportation, agriculture and justice. Hundreds of thousands of federal employees will find themselves on leave or are forced to work without pay few days before Christmas.
At the signing of a bill to the White House, Donald Trump said the government was « fully prepared for a very long paralysis », although almost no one expects such a thing.
The president has tried to blame the Democrats, although he argued last week that it would be « proud » to claim responsibility paralysis of the government in its struggle for the construction of the wall. Campaigning it two years ago, Mr. Trump declared that the wall would erect « so fast you’ll headaches. » He also promised that Mexico would pay the price, what Mexico said he never will.
« This is our only chance (…) to have excellent security at the border, » said Donald Trump Friday at the White House. Democrats will take control of the House of Representatives in January and will oppose the massive financing of the construction of a wall.
There is just one week, Mr. Trump insisted in a televised meeting that was held in the White House to take responsibility for a partial suspension of the activities of government in order to get the Wall its border. « It is I who shut up, » he said.
But with hours elapsing before the deadline of midnight, he sought to redefine the debate and blame Democrats deadlock that threatens hundreds of thousands of federal employees during the holiday season.
The White House said that Mr. Trump would not go to Florida on Friday as planned for the Christmas holidays if the government was closing.
The murder of journalist Khashoggi was ordered by then Saudi intelligence chief Ahmed Asiri and attributed to the Saudi consulate general attaché in Istanbul, who reportedly served as the kingdom’s resident spy in Turkey, reported Tuesday. the Sabah newspaper.
According to the source, citing a police source, Ahmad Abdullah Muzaini, the attaché of the Saudi Consulate General in Istanbul, was inside the Saudi consulate building on September 28, when Khashoggi visited for the first time. times in the necessary premises. to receive papers for remarriage.
The newspaper also said that on September 29, Muzaini flew to Riyadh, where he met with Asiri and received instructions on the tasks of a 15-person special group, who then arrived in Istanbul to assassinate him. journalist.
On 1 October, the attaché returned to Istanbul, where he informed Saudi Arabian Consul General Mohammed al-Otaibi about the plan to assassinate the journalist. On October 2, when Khashoggi was already dead, Muzaini returned to the Saudi capital, the media added.
Khashoggi, known for his criticism of Saudi politics, recently worked as a columnist for the Washington Post. The journalist was last seen in the Saudi consulate in Istanbul on 2 October.
After more than two weeks of denials, Saudi Arabia admitted Friday on state television that the journalist was killed in a fight in the consulate. Riyadh detained 18 people for their involvement in the incident, and at least five Saudi officials, including Asiri, were removed from office, with the Khashoggi case gaining momentum.
