Researchers say fossil shows humans, dogs lived in C. America in 10,000 BC

The fossil of a jaw bone could prove that domesticated dogs lived in Central America as far back as 12,000 years ago, according to a study by Latin American scientists.

The dogs, and their masters, potentially lived alongside giant animals, researchers say.

A 1978 dig in Nacaome, northeast Costa Rica, found bone remains from the Late Pleistocene.

Excavations began in the 1990s and produced the remains of a giant horse, Equus sp, a glyptodon (a large armadillo), a mastodon (an ancestor of the modern elephant) and a piece of jaw from what was originally thought to be a coyote skull.

“We thought it was very strange to have a coyote in the Pleistocene, that is to say 12,000 years ago,” Costa Rican researcher Guillermo Vargas told AFP.

“When we started looking at the bone fragments, we started to see characteristics that could have been from a dog.

“So we kept looking, we scanned it… and it showed that it was a dog living with humans 12,000 years ago in Costa Rica.”

The presence of dogs is a sign that humans were also living in a place.

“We thought it was strange that a sample was classified as a coyote because they only arrived in Costa Rica in the 20th century.”

The coyote is a relative of the domestic dog, although with a different jaw and more pointed teeth.

“The dog eats the leftovers from human food. Its teeth are not so determinant in its survival,” said Vargas.

“It hunts large prey with its human companions. This sample reflects that difference.”

Humans are believed to have emigrated to the Americas across the Bering Strait from Siberia to Alaska during the last great ice age.

“The first domesticated dogs entered the continent about 15,000 years ago, a product of Asians migrating across the Bering Strait,” said Raul Valadez, a biologist and zooarcheologist from the National Autonomous University of Mexico.

“There have never been dogs without people,” Valadez told AFP by telephone.

The presence of humans during the Pleistocene has been attested in Mexico, Chile and Patagonia, but never in Central America, until now.

“This could be the oldest dog in the Americas,” said Vargas.

So far, the oldest attested dog remains were found in Alaska and are 10,150 years old.

Oxford University has offered to perform DNA and carbon dating tests on the sample to discover more genetic information about the animal and its age.

The fossil is currently held at Costa Rica’s national museum but the sample cannot be re-identified as a dog without validation by a specialist magazine.

“This dog discovery would be the first evidence of humans in Costa Rica during a period much earlier” than currently thought, said Vargas.

“It would show us that there were societies that could keep dogs, that had food surpluses, that had dogs out of desire and that these weren’t war dogs that could cause damage.”

U.S. extradites Iranian man over alleged sanctions evasion scheme

The United States has extradited from Panama an Iranian national accused of evading economic sanctions against Iran by illegally exporting U.S. technology. He is scheduled to appear this Monday before a court in Seattle.

Reza Dindar, 44, was extradited on April 17 after being detained in Panama since July 2025 on charges related to export control violations between 2011 and 2012, allegedly carried out through companies based in China.

The defendant appeared before a U.S. district court in Seattle, where he faces charges of violating sanctions imposed by the United States on Iran in 1995 during the administration of Bill Clinton. These sanctions prohibit the unauthorized export, re-export, or supply—directly or indirectly—of U.S. goods, technology, or services to Iran or its government.

According to the indictment, between 2010 and 2014, Dindar led the company New Port Sourcing Solutions in Xi’an, China, which allegedly concealed the procurement of U.S. products for shipment to clients in Iran.

Elon Musk skips French court appearance over X investigation

Billionaire Elon Musk did not appear this Monday before French authorities, who had summoned him for a voluntary statement as part of an investigation into his social media platform X, prosecutors told AFP.

The platform has been under investigation since early 2025 following complaints from lawmakers alleging bias in its algorithms, which may have altered its functioning and interfered in politics in France.

The probe has since expanded to include other alleged offenses, such as complicity in the distribution of child sexual abuse material, as well as the role of Grok in spreading denialist content and sexually explicit fake images.

In early February, investigators raided X’s offices in Paris. The company has denied any wrongdoing, describing the searches as “political” and “abusive.”

At that time, the Paris prosecutor’s office summoned Musk and former CEO Linda Yaccarino to provide voluntary testimony as those responsible for the platform during the period under investigation.

Paris prosecutor Laure Beccuau also stated that X employees were called to testify as witnesses between April 20 and April 24.

The Secretary of Security of the State of Mexico, Cristóbal Castañeda, reported that the victims include two Colombian nationals, one Russian, and one Canadian. Additionally, two other individuals were injured due to falls, according to a statement from local authorities.

President Claudia Sheinbaum expressed concern over the incident, stating on social media that “what happened today in Teotihuacán deeply pains us.”

Federal authorities recovered a firearm, a knife, and ammunition at the scene, which remains under the protection of state police and the Guardia Nacional, according to the federal Security Cabinet.

Located about 50 kilometers from Mexico City, Teotihuacán is a major tourist destination frequently visited by both domestic and international travelers.
