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.”

Dozens of U.S. lawmakers oppose Afghan immigration freeze after Washington shooting

Published

Sixty-one members of the U.S. Congress have urged the Trump administration to reverse its decision to halt immigration processing for Afghan nationals, warning that the move unfairly targets Afghan nationals following a deadly shooting involving two National Guard members.

In a letter addressed to Secretary of State Marco Rubio and Homeland Security Secretary Kristi Noem, the lawmakers said the incident should not be used to vilify Afghans who are legally seeking entry into the United States. They stressed that Afghan applicants undergo extensive vetting involving multiple U.S. security agencies.

The letter criticized the suspension of Special Immigrant Visa processing, the termination of Temporary Protected Status for Afghanistan, and broader travel and asylum restrictions, warning that such policies endanger Afghan allies who supported U.S. forces during the war.

 “Exploiting this tragedy to sow division and inflame fear will not make America safer. Abandoning those who made the courageous choice to stand beside us signals to those we may need as allies in the future that we cannot be trusted to honor our commitments. That is a mistake we cannot afford,” the group said.

The U.S. admitted nearly 200,000 Afghan nationals in the wake of the U.S. withdrawal from Afghanistan.

Thousands of Afghans who worked with the U.S. military and their families still wait at military bases and refugee camps around the world for a small number of SIVs.

Chairman of US House intel panel criticizes Afghan evacuation vetting process

Published

Chairman of U.S. House intelligence committee, Rick Crawford, has criticized the Biden administration’s handling of Afghan admissions to the United States following the 2021 withdrawal from Afghanistan.

In a statement, Crawford said that alongside large numbers of migrants entering through the U.S. southern border, approximately 190,000 Afghan nationals were granted entry under Operation Allies Welcome after the U.S. military withdrawal. He claimed that many of those admitted lacked proper documentation and, in some cases, were allowed into the country without comprehensive biometric data being collected.

Crawford said that the United States had a duty to protect Afghans who worked alongside U.S. forces and institutions during the two-decade conflict. However, he argued that the rapid and poorly coordinated nature of the withdrawal created conditions that overwhelmed existing screening and vetting systems.

“The rushed and poorly planned withdrawal created a perfect storm,” Crawford said, asserting that it compromised the government’s ability to fully assess who was being admitted into the country.

He said that there 18,000 known or suspected terrorists in the U.S.

“Today, I look forward to getting a better understanding of the domestic counterterrorism picture, and hearing how the interagency is working to find, monitor, prosecute, and deport known or suspected terrorists that never should have entered our country to begin with,” he said.

The Biden administration has previously defended Operation Allies Welcome, stating that multiple layers of security screening were conducted in coordination with U.S. intelligence, defense, and homeland security agencies. Nonetheless, the evacuation and resettlement of Afghan nationals remains a contentious political issue, particularly amid broader debates over immigration and border security.

U.S. President Donald Trump’s administration recently ordered its diplomats worldwide to stop processing visas for Afghan nationals, effectively suspending the special immigration program for Afghans who helped the United States during its 20-year-long occupation of their home country.

The decision came after a former member of one of Afghanistan’s CIA-backed units was accused of shooting two U.S. National Guard soldiers in Washington, D.C.
