Scientists find dinosaur ancestors ‘may have been tiny’

Dinosaurs are usually thought of as these giant creatures, but the results of new research released this week outline a different view and find that they might have actually started out small.

This evidence comes from newly described fossils found on Madagascar island, off the east coast of Africa, which indicates the creatures lived about 237 million years ago and stood just 10cm tall.

Scientists say the specimen may also help clarify the origins of pterosaurs, which were winged dinosaurs that ruled the skies during the time of dinosaurs.

Co-author of the research study, Christian Kammerer, from the North Carolina Museum of Natural Sciences told Science Daily this week that “there’s a general perception of dinosaurs as being giants.”

“But this new animal is very close to the divergence of dinosaurs and pterosaurs, and it’s shockingly small,” she said.

The specimen, named Kongonaphon kely, or “tiny bug slayer”, was found in 1998 in Madagascar by a team of paleontologists, led by John Flynn from the American Museum of Natural History in New York.

Dinosaurs and pterosaurs both belong to the group Ornithodira. Their origins, however, are poorly known, as few specimens from near the root of this lineage have been found.

The description and analysis of this fossil and its relatives, published on Tuesday in the journal Proceedings of the National Academy of Sciences, may help explain the origins of flight in pterosaurs, the presence of “fuzz” on the skin of both pterosaurs and dinosaurs, and other questions about these charismatic animals.

“This fossil site in southwestern Madagascar from a poorly known time interval globally has produced some amazing fossils, and this tiny specimen was jumbled in among the hundreds we’ve collected from the site over the years,” Flynn said.

“It took some time before we could focus on these bones, but once we did, it was clear we had something unique and worth a closer look. This is a great case for why field discoveries — combined with modern technology to analyze the fossils recovered — is still so important.”

“Discovery of this tiny relative of dinosaurs and pterosaurs emphasizes the importance of Madagascar’s fossil record for improving knowledge of vertebrate history during times that are poorly known in other places,” project co-leader Lovasoa Ranivoharimanana, professor and director of the vertebrate paleontology laboratory at the University of Antananarivo in Madagascar told Science Daily.

“Over two decades, our collaborative Madagascar-US teams have trained many Malagasy students in paleontological sciences, and discoveries like this helps people in Madagascar and around the world better appreciate the exceptional record of ancient life preserved in the rocks of our country.”

Afghan border forces prevent illegal entry of hundreds into Iran

Security forces at the Islam Qala border in Herat province prevented hundreds of young Afghans from illegally entering Iran.

Officials from the 207 Al-Farooq Army Corps said that around 530 people attempted over the past two days to illegally enter Iranian territory through areas of Kohsan district in Herat, but border forces detained them and transferred them back to their original areas.

Meanwhile, officials in the local administration of Herat said that due to severe cold along the illegal migration route to Iran, three Afghan migrants have lost their lives in the Kohsan district of the province, and a shepherd has also died there for the same reason.

Mohammad Yousuf Saeedi, spokesperson for the Herat governor’s office, said that some statistics and images shared on social media regarding the incident are not reliable.

According to him, further investigations are underway to determine whether any individuals have died on the other side of the border.

US pauses green card lottery program after Brown University shooting

Published

on

President Donald Trump suspended the green card lottery program on Thursday that allowed the suspect in the Brown University and MIT shootings to come to the United States.

Homeland Security Secretary Kristi Noem said in a post on the social platform X that, at Trump’s direction, she is ordering the United States Citizenship and Immigration Services to pause the program, the Associated Press reported.

“This heinous individual should never have been allowed in our country,” she said of the suspect, Portuguese national Claudio Neves Valente.

Neves Valente, 48, is suspected in the shootings at Brown University that killed two students and wounded nine others, and the killing of an MIT professor. He was found dead Thursday evening from a self-inflicted gunshot wound, officials said.

Neves Valente had studied at Brown on a student visa beginning in 2000, according to an affidavit from a Providence police detective. In 2017, he was issued a diversity immigrant visa and months later obtained legal permanent residence status, according to the affidavit. It was not immediately clear where he was between taking a leave of absence from the school in 2001 and getting the visa in 2017.

The diversity visa program makes up to 50,000 green cards available each year by lottery to people from countries that are little represented in the U.S., many of them in Africa. The lottery was created by Congress, and the move is almost certain to invite legal challenges.

Nearly 20 million people applied for the 2025 visa lottery, with more than 131,000 selected when including spouses with the winners. After winning, they must undergo vetting to win admission to the United States. Portuguese citizens won only 38 slots.

Lottery winners are invited to apply for a green card. They are interviewed at consulates and subject to the same requirements and vetting as other green-card applicants.

Trump has long opposed the diversity visa lottery. Noem’s announcement is the latest example of using tragedy to advance immigration policy goals. After an Afghan man was identified as the gunman in a fatal attack on National Guard members in November, Trump’s administration imposed sweeping rules against immigration from Afghanistan and other counties.

While pursuing mass deportation, Trump has sought to limit or eliminate avenues to legal immigration. He has not been deterred if they are enshrined in law, like the diversity visa lottery, or the Constitution, as with a right to citizenship for anyone born on U.S. soil. The Supreme Court recently agreed to hear his challenge to birthright citizenship.
